  1. Good evening growers, Setup: Hydro drain to waste. Going into week 1 of flower. Strain: RQS Green Crack Punch Using Shogun nutrients. Silicon Ph down to 5.8 A & B Katana roots Calmag Zenzyme Sumo boost. During veg i went up to 1.6 EC So I am starting week 1 of flower at 1.6 EC & will increase it by .2 each week. What I want to know is do i have the right idea? Thanks
  2. Hello, Looking for some advice, New to coco, about 10 days into early veg with some ICC in 2l pots estimate around 3 or 4 days til re pot up to 16L as roots just starting to show at bottom of pot. like a plonka already made a rookie mistake and only fed 24hr water for first 2 feeds, as i am now led to believe i should of at least started with a rhizo 2ml per L 0.6 EC i have been feeding every other day for first week to give the roots some growth, began feeding every day on day 7. from the start i have been feeding them 300ml and been getting 75ml to 100ml in run off so a good bit over the 25% minimum required, the clones were well established in rockwool. from day 7 plants have been on (ml per 10L) rhizo 20ml calmag 2ml superthrive 3ml zenzime 2ml Then ECd with CANNA A & B to 1.0 usually that's usually around 10ml of each PH down to 5.8 Now here comes the kicker testing the run off, consistently i have been getting readings of 0.4/0.6 EC 6.0ph, im assuming this isnt normal and is a sign the plants want more nuets as they are using up a good amount of the EC, little bit nervous of increasing the EC already as i read early veg should be around the 0.8EC mark plants look perfectly happy at the minute but i am by no means an expert........just an apprentice.... Environment sat between (25C RH 40% lights on) (21C 50% RH) lights of (18/6 cycle) i am using a blue lab truncheon and ph monitor for those wondering. Any advice much appreciated, Thanks again JB
  3. Firstly i will admit that i still have my growing L plates on as i am still a novice in the game, however once i start looking into things and taking an interest i tend to become a nerd and spend to much time researching. Granted i am trying to run before i can walk, but the subject interests me and id like to possibly test it out at some point in the future. I have been seeing a few growers running extremely High EC levels recently ( any where from 5-8EC ). To some one like me who constantly sees "less is more" and people hitting nice results from 1-1.2 EC this seems beyond ridiculous, however the results and the science speak for themselves and i can't argue with them. Some of the growers using these levels are doing so under LEDs and talk about the plants transpiration being dramatically affected by the switch to LED to the point where plants require twice the E.C level just from being used on LED alone. Apparently LEDs cause the plants to transpire less than half that of tradition CMH/HID in which case twice the nutrient EC level was needed to give the plants the correct amount of nutrition in a smaller volume of water. Another thing to note is that the strain also plays a factor in weather or not plant can take any given EC solution as it was said some plants could take 8EC upwards, where as other would not react kindly to anything over 1.6 This all massively interest me as its out of the "norm" for your average grower and is something that seems to be getting very good results interns of quality and yield. very curious to know what @GSZZ @tokenroll@Owderb@badbillybob think, sorry to tag you guys. In my short time on here you guys have been the main members to stick out and be very knowledgable so curious to know what your options are!
  4. Hello there Looking for some advice please. I am about to start my third hydro grow in a Wilma 8 pot system bought in 2011. Previously and pretty successfully I had followed a feed chart in the Growell catalogue. This time round and following reading a couple of articles on importance of staying on top of EC I have made a rather impulsive purchase of a Bluelab Truncheon, however back home and ‘out of the box’, I have a couple of questions… Firstly, the Wilma involves completely weekly reservoir change. Following a daily EC reading is it basically a case of adjusting basic nutrients (Samurai G&B in this case) or water in the reservoir as necessary, or would other aspects of the feed regime need adjusting maybe daily? Secondly, particularly into flowering, moving plants off the top of the reservoir for water/ nutes etc is highly disruptive once a week let alone throughout the week, assuming a daily EC check and necessary adjustments of water and nutes, is it usually possible to manage all this through the small(ish) hole where the dripper pipe feeds into the reservoir or will plants need to be moved around more than usual within the usual weekly res change? Basically, how do you guys using a Wilma get on with using EC wands like Bluelab and managing nutrients thereafter? Obviously, I want the best for the plants and would like to understand this technology but is it practical for use with my old Wilma or should I just stick with the feed chart? Any thoughts much appreciated! YP
  5. Hi all. Ive just bought a Bluelab EC Truncheon and would like any aditional info in using it and general info on EC. Im in Hydro with AN GMB nutes and a small Voodoo Juice not going to use boosters i want to keep it simple. Ive alreay read about using the nutea at a lower strength and build up as they can be abit strong but with an EC meter ill be able to monitor it properlt for once, so here is the info ive gathered from browsing the forums. If anyone can add/correct anything or give knowledge the thanks in advance. ---------- Small plant needs 400-600ppm, bigger plant 700-800 and heavy flower needs 900-1200 max. if, as your tank levels drop, the e.c level rises, = too much fert if, as the tank level drops, the e.c drops, = not enough ferts 13/6 - w1 - pop bean - mix 1f 1r ---------- Small plant needs 400-600ppm, bigger plant 700-800 and heavy flower needs 900-1200 max. if, as your tank levels drop, the e.c level rises, = too much fert if, as the tank level drops, the e.c drops, = not enough ferts --------- Advanced Nutrients use EC scale 700 eg 2.4EC x 500 = 1200ppm (500 scale) or 1200ppm / 500 = 2.4EC 2.4EC x 700 = 1680ppm (700 scale) or 1680ppm / 700 = 2.4EC ---------------- General Grow Regime Example Vegetive feeding 0.6-1.2 EC Flower 1.2-1.6 EC Flowering formula for 8 weeks using Sensi bloom A+B, Big bud and Overdrive. Medium Feeding:- Week 1:-Add equal parts of sensi bloom A+B to reach 1.2EC Week 2:-Add equal parts of sensi bloom A+B to reach 1.3EC Week3:-Add equal parts of sensi bloom A+B to reach 1.2EC, then top off with Big Bud until a reading of 1.4EC is reached. Week4:-Add equal parts of sensi bloom A+B to reach 1.1EC then top off with Big Bud until a reading of 1.5 is reached. Week5:-Add equal parts of sensi bloom A+B to reach 1.1e.c then top off with Big Bud until a reading of 1.6EC is reached. Week6:-Add 2.5mls per litre of Overdrive, then top off with equal parts of Sensi Bloom A+B until a reading of 1.6EC is reached. Week7:-Add 2.5mls per litre of Overdrive, then add equal parts of Sensi bloom A+B until a reading of 1.4EC is reached. ----------- Does this all make sense???
  6. Hi All Starting to get back into this after a LONG time out and buying absolute rubbish to smoke! My memory is very hazy tbh so been watching a few Vids etc. I have roots just poking out of RRiot cubes and looking transplant into 3" cubes. What EC do i need, just looked at this video and he states 400PPM, is that not about 0.6? That seems high to me?? Plus his PH seems low, should it not be 5.8, should he not of soaked them for longer and let it 'level off' as we know RW increases PH. Also surely he should of trimmed them roots, would they not rot off at that length? I am SO looking forward to this guys, i've missed my own looked after and cared for smoke, i have some nice Gelato!! I also might add a tiny bit of Nitrozyme as well to the soak mix. Cheers guys and so glad to be back on here, i look forward to replies and the great chat, god i have MISSED this place......... VIDEO -

  8. Hello, I’m just wondering in the ‘Ecotechnics Evolution Digital Fan Speed Controller’ works with the new EC fans or not? If so does it work with pretty much all fans? Cheers
  9. Do I need an EC pen as necessity? What is it for? Can someone point me towards a guide pls? I'm about to start my first coco gro...
  10. Hello everyone, thanks for approving me! <3 I was searching as a guest last night for answers, but i was unsuccesful.. If a thread with this question already exists, PLEASE point me to it so i can educate myself. I also tried to ask a few questions on the Growdiaries site, but that limits you to 280 Characters and that is not even remotely enough to explain the (ill call it mini problem) im having. I am 9 weeks into my very first grow. After some extensive research on ADHD, I chose one of the exotics, a landrace heirloom sativa, Dr. Grinspoon as the one i want to grow, thinking the end result will help my other half to be motivated and productive during the day. (But thats not the question.) Following all Advanced Nutrients calculators online and guide sites specifically made for Advanced nutrients and growing in coco. The recommended amounts per litre are somewhat reasonable when you look at them, i mean its only reasonable to have 4ml A&B per litre of water during late flower right? Well my TDS pen says otherwise. From what ive gathered, Early seedlings like to be at a range of 300-500EC Early and mid veg it likes to be at a range of 1.1-1.5 and early and late bloom it likes to sit at 1.7-2 (average numbers ive gathered over many different sites and forums) That is understandable and easy to follow. The problem comes here: Even though i am on week 9, because of some complications dring early seedling phase, my Dr.G didnt develop very fast, so i am currently using nute strength for week 3 of veg. The recommended amount of nutes at this stage is 3ml(A&B) of sensi grow and 1.5ml of vitamin-B52 per litre. That brings my 1 litre of water all the way up to 2.2 and im not even at full recommended dosage, or not yet using any supplements that ill have to be using during flowering. That panicks me a little and i dont really want to give that to my G as i already stressed it plenty during early veg with transplanting it into a massive pot with poor drainage. What i do is, i add all the recommended amounts, and then i add 250ml of extra bottled water (using still bottled water from the supermarket that reads at 0.18) to bring the EC down to 1.7-1.9 which Doc seems to be okay with. My question is: Is this right? i mean when i add that 250ml extra water to dilute the feed, the recommended measurements stop being per litre and begin being per 1.25 litre. Is that right thing to do? what happens when i reach full recommended strength and it skyrockets the EC all the way up to 3 (and i know it will considering the nubers im having right now). Do i still keep diluting it with more fresh water until i reach the recommended EC? Or do i keep the feed measurements at 1 litre ignoring the EC levels? I already burned the plant when i had the poor drainage situation and the EC rose up to 5 and i had to transplant it to fresh medium so it wouldnt continue dying. Doesnt diluting the feed made with the recommended amounts also lowers the strength, making the feed weaker than what is the recommended? Any Info would be very much appreciated, and again, i was searching all night to find this answer, and its been bothering me for the last few weeks, If an answer or a similar topic exists already and i missed it PLEASE point me to it so i can read and gather info Thanks for reading and sorry if its too long.
  11. What do you guys reckon is the best environment controller for hyperfans?
  12. Hi, I'm starting my second DWC grow (5 plants in one big pot) and one of the things I hated was lifting the lid and checking the PH/EC (especially when the plants grew big). I was thinking to get a Hanna or Bluelab Guardian/combo meter type setup where I could leave the probes in continuously to make my life easy. I was wondering if the probes can be left entirely submerged (including some of the cable that goes back to the meter) or is it just the tip of the electrodes that can be submerged. I cant find any info on how these things are installed and would be grateful for any advice from someone who's is in know. Manufacturers always show the setup on the left, whilst I just want to dunk it in the drink like on the right....if you guys do it like the setup on the left, how do you ensure that only the end of the sensor is submerged (I always fill up to slightly different levels and also as the plants drink the levels lower). I don't feel brave enough to permanently install them by cutting holes in the side of the basin. +-------------------------------+ +-------------------------------------+ | | | | | | | | | METER | | METER | | | | | | | | | | | | | +-------------------------------+ +-------------------------------------+ \--- | | \- \ - | \ ----- | / | -----/ \ | \ -\ | / | -- / / \ | / | | | | / \ +----|-------+ / / | | | / | \ | | | / | | | \ / \--------------+----+--+----+-------------------------------------------|-----------------------------------| | | | \ / \ | | | / | | | \ | \ | | / / | | | | | \ | | / / | | | +---|-------+ / \ | | | | | | | | | | / \ | | +----+-+----+ / | | | | | | \ +--+ | | / | | | / \ | | | | | | / \ +-+ / | | |--------------------------------------------------------------------------------------/ Cheers
  13. Afternoon everyone, I’m after some advice and wondering if anyone can help me out with R.O units and which is best to go for. My background e.c is 0.7 so water is terrible and I’m thinking it’s worth the investment now to be able to work with clean water and really give the plants a proper feeding instead of loads of unknown crap. My local hydro shop wants silly money for a unit so been looking online but there’s so many to choose from 3/4/5/6 stage which will be suitable? I’m guessing just a bog standard 3 stage will be fine but if anyone has experience with them I’d be grateful. Cheers
  14. I’m currently on week 2 of flower with 6 stardawg girls. I’ve been using canna nutrients from the start and have been following the guide Almost exactly, I’m currently feeding at EC 1.7 but I’m reading that this is too high?? They seem to be happy but now I’m worried about bumping the EC up which is what the guide says to do as you get further into flower. Any tips or advise would be much appreciated
  15. Morning all a quick question regarding ec I got a bluelab truncheon yesterday and tested my tap water it’s coming out at 0.7/0.8 now with it being so high when I start my dwc which will be in a oxypot Xl so 70litre res what should I be aiming for as a start point. My understanding is to stay on the lower end of the scale when it comes to feeding in dwc. I’m using AN Sensi Grow A+B and will be addingn some voodoo juice as I’ve read some good things about it. So Do I only mix feed in and make it up to say 0.9 which is only 0.1 of added grow or go upto 1.0 which still doesn’t seem a lot at only 0.2 of food. Cheers in advance
  16. Hi Everyone, I am new here so firstly I would like to say hi to everyone and that I look forward to what I hope will be a long journey here on this forum. I have never grown before and I am currently prepping for my first, I will be germinating this weekend. I have just been calibrating my new pH & EC readers (both are Essentials) and getting base readings for our water. Here's where things are getting a little strange, we have an undersink reverse osmosis filter (we've had this for some time now as I don't want the tap water for obvious reasons, I have however replaced all the filters a few days ago to get the best of the best for my girls-to-be) and I know manufacturer (iSpring Water Systems) specification is that water pH should come out at 7.4, it came out at 8 which is fine for myself and will just have to use a lot of down, but the EC reading has come out at 0.8, which even as a virgin grower I know is waaaay higher than the majorities. I know that during filtration some ionised minerals are added (calcium, magnesium, sodium & potassium), but this has thrown me off completely as I now have no idea where I'm at with nutrients. My plan was to start the seedlings off with around 0.5-0.6 EC (assuming a base of 0.2) as I am growing in coco, so 0.8 is already higher than that without any nutes added. Should I just treat this as my base? Should I use normal tap water? I really am lost and have no idea how to even find the answer. Any help or general beginners advice would be hugely appreciated. I'm so excited to be joining this wonderful community and can't wait to progress, happy growing!
  17. Hi all,, a couple of quick questions for you? 1, Does your EC have an effect on the temp of you res water? What i mean by this is, does the water in your res warm quicker/easier if the EC in your water is higher? 2, What temp is ideal for a res? Ive modded my wilma so the roots dont go into the res in the thought that i may be able to get away with slightly higher res temps if the roots are in it. Lights off im at 19c and lights on it climbs upto 22c. Ive tried everything to bring res temps down and really dont wanna have to buy a chiller. Thanks in advance...
  18. ph

    Ok, the new problem... My PH is a bit low for my feed. So that is going to be adjusted. However, for those who asked in a previous thread what the PH and EC were, well I splashed out and bought myself a crissy prezzie of an EC and PH meter, they arrived today. I have tried el-cheap-o route, splashed out on a couple of middle of the range meters that were about the £35 mark each. Normally about £99 the pair, got then on deal via a trader that I have used several times for substantial purchases and got them both for £69.99. So these are not your £20 grow shop cheap as chips, ok for a grow meters. The PH meter was easy to set up, there is an option to set the alternative end standards of 4.0 and 10.0 on the PH scale, I just went with the Neutral PH 7 standard for now. The EC meter was pretty much same sort of deal, I happened to have bought, quite by accident a month or so back, EC28 buffer... Single button push calibration... Couldn't ask for more. OK now, those people asking what my water EC and PH is. This is a current state that IS GOING TO BE CORRECTED. Feed mix... PH 4.3 EC 1.3 Separate Water (for all uses, including adding more water to the pot when dry between feeds) PH 4.8 (Originally I set the PH to 7 for a baseline, was aiming for PH5 when PH was too high) EC 1.0 The water I used to water and other things like spraying was aimed at being PH 5 as I needed to drop the PH of the water in the pot as it was a bit high, the test paper system I used was pretty good guide and PH had risen to above 7. So now I can make the required changes to the current feed mix, readjust the water back to PH of 7.
  19. Hi, Does anyone know of a good summary like a table of sorts maybe, that covers all the combinations of PH/EC behaviour, perhaps something like: EC PH PLANT IS DOING stable stable <chilling> down down <needs more nutes> etc etc I keep reading like tit-bits here and there but is there an authoritative reference? I'm in hydro if that makes any difference. Appreciate any info/links Thanks,
  20.

  21. Right quick question tap water ec is 0.9 and i know people say start bloom at 1.2 ec but my plants been vegging a good 7 weeks from clone and feeding on ionic grow at ec of 2.1 that was including background of 0.9 so 1.2 worth of grow add to tap water ec , now they just starting 3rd week in flower so empty res and filled with water same ec 0.9 added bloom upto 1.9 should i go higher or will that be ok? Thanks barney

  23. Hi All After some help/advice please. Been using a Bluelab truncheon for a while now and the one i have now is just over 12 months old. I always have looked after my kit and always checked this against calibration fluid and if reading low cleaned with Jif etc. But today i tested in the calibration soulition (2.8E.C) and im getting a high reading of 3.4....... Anyone know what to do if these read too high....????... Thanks
  24. Hi ya guys, This will probably get merged, but thought I'd give it a go anyway. I've posted this on the end of the coco thread too. just wondering what people do with seedling and early veg, I always seam to struggle with this bit, suffering from super slow growth and last time yellowing of the bottom leaves, are you watering them little and often or, flood and drain from day one and let them dry out or what? Cheers guys Atb✌
  25. I left my friend to take care of my friends because I wanted to go on holiday for a week. So the temperatures were too big, I know that. And he once forgot to put the water pumps back to the tray after lowering down the ph, which I asked him to do. Next day he returned when lights turned on. and Three plants were completely dead. Like their leaves were all hanging. He obviously understood it was the water which girls wasnt receiving. and turned pumps back on. They survived, and the others have suffered as well as I now see when I returned. All the lower parts of leaves are yellowing. Although there are so many leaves, maybe the plant tries to get rid of them naturally. Those who where effected the most by water shortage, the lower leaves completely dried off. And I have nutrient burns as couple of times when water was lowering in its quantity EC rised to 1.8-2.0 I've emptied the tank and refilled with EC 1.4... and today is EC 1.6... Too much again... It is a fourth week of flowering. Could it be that, because of the stress they received, they just drink water and dont want to uptake any nutrients? Why EC is rising so fast? PH is rising was aswell, but at least there is ph down for it...
