  1. Hi all, I wanted to purchase a nice branded, widespread shade with air cooling ability. At the time, I was unable to find anything so I made my own. I've had this for some time, but thought I'd finally share as I've installed some sensors and it's given me the chance to photo the previous work I've done to convert it. Unable to find anything, I decided I would modify my current shade to suit the 1000w double end (DE) light setup. To my surprise, it was surprisingly easy because MOST euro shades I have measured fit inside this unit. As well as recording what I've done, consider this a how-to. Before you say I bought a DE 1000w shade I had one to hand and didn't see the need to buy another shade just to wire it myself. If anyone know's of a decent branded DE shade please share, but for now, here's my how too including sensor installation for retro fitting. First, you'll need; Air cooled shade of your choice - I was extremely happy with the build quality and overall integrity of the SunSystem's shades so grabbed myself the 6 inch setup. Double ended 1000w system - measure the length of the euro shade - ensure it will fit inside. I'm using an Adjustawatt 1000w DE 400v setup. I'm hoping to replace this soon but it shouldn't matter what ballast or bulb you use. Drill / bits, sizing depending on the wire size of your setup Wire cutters Insulation tape Various sized grommets (depending on your setup) A camera - to share with your local uk420 forum Test fit the euro shade into the unit, if the length is measured correctly it will fit inside, open up and support itself within the shade. Without having to modify the end reflectors. If the euroshade does not fit, modify it best you can to be slightly wider than the overall width of the air cooled shade. There will be a ledge inside, this is what the euro shade sits on. You can then best the lamp position into the air cooled lamp, with the shades wings giving the typical V stance, they will be supported. Cutting the reflector material is easy using tin snips. Just be careful with any cut metal and ensure you use needle files to deburr edges and hoovering is a must - try and do metal drilling / filing outside (shed). Additional; I have installed three temperature/humidity sensors and a light sensor into this unit. I'm using a 7 core wire to transfer the signal, which is why I've also included a roof sensor and an external shade sensor. I am measuring inside the shade temperature/humidity to understand the system, not to use as an environmental measure. Canopy height is the main temperature to go by, this will be done separately. As well as lower tent temperature. I am using DHT11 sensors and TS2561 light sensor. Once you've collected your items, take apart fully the air-cooled shade. You'll need to re-wire the ballast to bulb loom and feed it into the light. There may be a hole already, which would save you some drilling time. Ensure when removing part of the shades reflector, you install the suitable grommet to allow for the cable to run. Heat and pressure on the wire will eventually short out. With 400v setups being common with DE units, you don't want this to happen! Use plenty of electrical tape between the wires, I opted for amalgamating tape around the lot at the end. Holes will be required for any sensors you wish to install. Make sure any temperature/humidity sensors are not directly against a surface, the airflow on surfaces is inaccurate as a measurement. 3mm hex pillars are an easy way to do this. I'm unsure the effects of air flow causing temperature variation in this setup, but until someones tried it and proven it's inaccurate then I'm hoping to gather some useful data. Lay the euro reflector down inside the unit, if all is well, it will fit and the sides will hold in place. I've tried different shades, I was unable to find one that didn't fit. Of course, the width of the euro reflector will be important as this will determine the height and central location of the lamp. Just ensure you measure it first; I'm certain most will fit. But check! Once in position, ensure all wiring is tucked out the way of air flow and confirm all wires are still secure. Plan your holes ahead of drilling. The side unit shows the wire for the tent roof sensor, the external shade sensor and the 7 core wire which has the sensor voltage and signals. Always mark up the wires if they use the same colours, I've notes wire colours for connections. I label the sensors, these will be the sensor numbers which will reference the programming code when I install them and begin to data log. Above are showing the grey 3 core wire for top of the tent sensor, 7 core wire and the largest power cable for the lamp. I placed my external shade temperature sensor near the safety catch for when the glass panel is open so I can secure it neatly. I'm sure there are options for shades with DE system's already installed, I've only found cheap units which I wouldn't personally buy. If someone already has an air cooled shade, but purchased a non-air cooled setup I hope this will be useful. The instructions are basic but clear; Be safe protecting any re-soldered wires Ensure wires are supported, not tight and use grommits when going through metal to ensure wires are not cut Do not use crimps with any high voltage wires - my personal opinion Don't coil high voltage cables Use cable ties on the wire inside the unit to ensure they don't get pulled out if knocked externally I'll post some of the data when I have begun to capture it. I'm still finishing off the main data collection system. Photos of the finished unit; Above showing location of the external shade temperature. Directing away from the light, to stop light impacting air values (potentially). There are a million places I would have put the sensor. However, of ease of installation and repeatability, I thought this location was best. Directly facing the lamp at such close contact may give me inaccruate results (unless I use top industry sensors). I'm not light expert, so I'm hoping for some feedback at light degredation at least - even if I'm unable to use as a comparitve value in other situations. The orange wire shown is the additional CFL lighting I have in the corners. White cable is for the corner fans. Showing below is the top air temperature sensor. Feedback is welcome, of course, please be nice, I'm new!
  2. I currently use 600w hps digital ballast systems. 9 plants to 1x 600w hps, 1 to 1.5msq. 20ltr soil. I wish to convert to LED. I have browsed KING LED 3000W lights due to their cost. A typical HPS at 600w is aprox 90k lumens. Looking at the specs of a 3000w King LED fixture it gives the lumen output as aprox 24k. Can anyone help me with this disparity? I really wish to switch to LED but want King LED prices..but 24k lumens sounds wrong for 3kw of LED light? Any advices and experiences sought. Thank you
  3. Hi, I am fighting heat at the moment and with regard to air cooled lights and was wondering if anyone has experience with this. Is there is a big benefit to cooling the lights down via a dedicated fan vs using the exhaust fan I already have? Cheers
  4. im new to this, can anyone advise me if i will get a reasonable yeild using a 600w dual spec bulb for 6 plants. they are in 10l pots in plagron batmix, around 18-20 inches in height and ready to go into flower. i only have that one light at the moment and wondered if i could get through this first grow with that alone. i plan on using some canna terra flores neutrients for flowering stage. sorry if this seems a stupid question im just learning
  5. Hi all I am looking to purchase a cheap LED for a tiny veg cab with limited height, around 90cm, its a small room and I currently have a 125w CFL in it. Enrionment is okay but I want higher wattage to cover 9 young plants and be able to raise my light up somewhat. I also know the LED will create some nice bushiness having used a bigger one before, and then I can really pump them in flower under a 600w digi hps in a parabolic. Thing is, being a Yorkshireman I am a tight arse, but I also know I do not need the advanced platinum sun shines out of the crystal backside of my creation series of light, just something with a max draw power of 300w from my socket, something equivalent to 300-450w of MH or HPS light. My imaginary budget is between £40-65. Can it be done? I know the tech is getting better all the time, and prices are coming down as more competitors come on the scene. Does anybody have a joyful story to tell of getting a bargain LED that literally just needs to 'do the job' nothing extra special. Ive considered HPS but even a smaller one will run too hot in there, and because of the space of the loft, flower room and veg cab do not want nor need to take on another ballast if I can avoid. Would ideally like to acheive 30w per plant so 9 x 30w somewhere around 300w of true wattage, but no more from its draw. I have done lots of searching myself, so just wondered if anybody else knows anything.
  6. Hi! I went away at the weekend and I think my electricity stopped for 12 hours. I was planning on harvesting today and I noticed my timer was 12 hours out. So the plants got full light during the dark hours for 1 / 2 days! Do you think this would have any negative effects on my crops? Or is it so close to harvest now that it does not matter anymore. Thanks for any knowledge!
  7. Hey all. I have recently just built a veg room in my loft, adjoining onto my main room. Dimensions: 1.7m long, 0.85m deep, 1.2m tall. Solid room made of beams and loft paneling, insulated with 50mm poly boards and then fully mylared. I Will be putting a 4 inch output fan in to vent out and leave door ajar to bring air in with an small desk fan to oscillate around, this will be done next week. Ive just fitted a 300w CFL with reflector in as I just had it doing nothing and as I speak running some tests with 3 hemp seeds just as a practice, As I am a newb to doing. I will be aiming to crack open my 5 Kalashnikovas (GHS) soon, and a choice of 1 or 2 others. I have a red diesel and Honeysuckle which keep taking my fancy. My temp is averaging at 24 degree, highest this week so far 25.7 and lowest is 23.1, light on 24.7. My light is as high as will go, around 1m high, with the 3 hemps on the floor. I soaked seeds for 30 min while I saturated coco in small pots with some root stim and let that just drain and soak in in the meantime. then just stuck the seeds 1cm into each pot. Took 3 days for them to rise which was yesterday and since that they have grown 4 inches. Now I know these are hemp seeds and they might grow differently I dont know that much, but 4 inch seems a lot to me. Could the stretch be having the CFL light up at 1m? All 3 pots already have a big root coming out of the bottom and im just giving them small amounts of Growers ark rootstim and first feed, little and otfen to keep moist. Im confident this environment is good enough to crack my Kalashnikovas soon. Is yet to be vented but I am installing a small 4 inch fan next week. But is the CFL good enough at that height as Im a bit surprised at the stretch of the testers im running. My actual area is only one half of the room, as it is long and narrow. Im aiming to be able to house 8 to 9 young plants when im confident over time in there in a 60x60cm deep garland tray. Would I be better switching to a cooler bulb in the hotter months as I feel all that CFL is a warm old thing. And if so, what are the best bulbs for that space? A lot of questions I know, but I love this site and trust you all to be as helpful as we always are. Thanks lots.!
  8. Hi all, I'm new on the forum and the growing world so bare with me please I was trying to find a better section where to post this but I couldn't seem to find one, so here it is. (Moderators feel free to move around, or please PM me before removing as it'll be a quite long one ). So, a bit of background. I've been a smoker/lover for about 20 years, then for unknown reasons I started having bad reactions to (I think) THC so I had to quit Now, this all CBD world is exploding all around, did a bit of research about medical strains and, as where I leave it's impossible to find anything but crap, I decided to give it a go and try and grow my own. Problem is I don't really know if these weaker strains will cause me the same problems when "consumed" So I'd like to stay on the cheap and upgrade further on in case of success. I've ordered some Sweet Nurse Auto CBD 5-10% THC/10-15% CBD and CBD Critical Cure 5% THC/8.5% CBD (and I also received a whole bunch (10/12) of high THC seeds), started buying some of the needed equipment and I'm "building" my tent (80x90x150cm, I used electrical pipes for the structure and I'll cover it with cardboard using emergency blankets as reflective material on the inside). As for lights I went for LED and I got a cheap COB 300w one off ebay (not sure if linking is allowed https://goo.gl/ugPPM6 ) Now the questions: I've been reading about fans and filters but I've seen on youtube some pretty experienced growers having good results without and saying that for air circulation it's enough to open the tent once/twice a day (https://youtu.be/lt-KNNAY80g min 4.14) And adding 1/2 small conventional fans for airflow. What's your take on that? This leads to opening the tent, from my understanding it's ok to open the tent given you respect the light cycle (hence you open it when the light is on and keep it close, especially during flowering, when the light is off). Is that right? Ventilation when the tent in closed. I was thinking to add a line of small holes close to the bottom on one side (where I'd put my fan so that it would kinda pull fresh air in from there) and the same on the top to the opposite side (from where the warm air is supposed to get out). Would that do? Also, shall I worry about the light leaking in from those holes or, making them small enough (say 6 holes 10mm), the amount of light will be irrelevant? Finally, last but not least, I'd like to go as "organic" as possible, avoiding chemical nutes (even because they require flushing and water is kind of an issue on the island where I leave). I do make my own compost (coffee ground, tea leaves, egg shells and all the veg waste from salad, greens, fruit etc...), would you use it when potting? What else you suggest to use as an aid? I think that's about it for the moment, be assured I'll be back bothering you guys with more questions once I'll start! I can't wait!!! I'll probably start with one because of the very small tent, most probably I'll go with the Sweet Nurse which is stated to be ready in 8 weeks from germination! Peace
  9. my mate has a 2.4x1.2x2.0 grow tent which he is running 2 x 1000w lights is to much or ok.
  10. So there's magistrates guidelines saying a personal grow is 9 plants per person with no more than 24 in one location before those guidelines supposedly change but it says nothing about how much light is used!!!! 9 x 1 plant 1000w scrogs would surely be taking the piss will domestic uk electricity suppliers notice that kind of thing ? even if you are paying for it, or is it they are not bothered as long as your filling their coffers ? So how much is too much for a perpetual personal grow in the average uk household ?
  11. hello again guys decided to get a 400w hps for my 90x90x185 tent currently got 4 autos in there under 250w hps would it be okay to put 5-6 plants under the 400w hps ? in 11 liter pots proberly try aut again see if i get any mre than 1 oz a plant unelss you guys think 5-6 photo plants would be better yeild thanks in advance guys
  12. Hey all. HUGH, PUGH,BARNEY,CUTHBERT,DIBBLE and GRUBB are now 10 days old. Has anyone tried placing the reflective film over the top of the pots? Covering the soil and reflecting the light back UP through the canopy? Will that aid Photosynthesis, or just confuse and disorientate them? Tried googling it.... And how to spell disorientate.
  13. Am currently looking into swapping current setup to The Gavita Pro-Lines E-series All In One Light Unit. with The master controller unit to suit.. Has anyone had any experience with the Gavita Setup? How did you get on? Digital Ballasts have been a concern for myself, as Many Years ago when I was looking originally to use them, they were throwing out magnificent rf to the point my radio didn't work (old fashioned I know )... but it knocked the frequency for the television out, so I felt it to be wise, to switch back to the magnetic ballasts. I'm aware of the cost difference and Overall performance showing that digital outperforms magnetic, It's just the radio frequency causing my delay Also is there much Light penetration difference between the 400v bulbs in the Gavita, in comparison with sunmaster or Sylvania? Technology always Evolves and its been a while, so I'm hoping maybe.. they have sorted the frequencies out? anyone care to clarify?
  14. Hey, So I am on my second grow and I have been getting really high recently..... Anyways because of time restrictions I only usually get to my plants at lights off. My tent is in my room and my radiators are on all night so my lights on is 6am-6pm, This is to minimise temp fluctuations, at about 6:30 each night I open the tent at dark to water them. Now because I have been really high i just assumed that opening the tent for 5-10 mins at dark to feed them wouldnt be an issue. Ive been doing this for 5 weeks now!!! My question is, Should I be preparing for my plants to hermie anytime now? so far though I dont see any hermies. (touch wood). AND I've stopped opening tent at dark now btw
  15. Ok so i'm going to starting my 2nd grow soon. Last time I used 600w lights and had a rather successful 1st grow but I think I overdone it on power considering I only grew 3 plants and don't intend to grow much more than that. So my question is as follows, I want to downgrade to the lowest possible light wattage whilst sticking with HID lighting, Ideally 250w since i'll be paying for the electric myself this time round but i'm not 100% sure if it'll do the job hence why I ask you lovely people.
  16. Hello all, I wanted to ask at what stage during flower do my plants need the most light to maximise yield? I currently veg under between 300w-450w hps but I'm ready to go to flower soon and will using two 600w lights. The reason I ask is I want to obviously yield as much as possible whilst keeping the lighting costs in check. I know some people the moment they go to 12/12 go straight to the bigger powerful lights but I just thought are the needed straight away? Could I just use a single 600w for the first couple weeks and then bring in more lights when the flowering really starts to kick in? I'm in a dr120 with 2 century digital ballasts that can be set to either 300w, 450w, 600w and super lumens. Cheers

  19. Hi, getting good yield and effects, but simply failing to get any smell from the buds. Have grown NL, ruderalis indica, ak48 and power africa, got a strawberry blue half way in flower now and hoping to get some smell from the cured bud this time. Growing as SOG under 150w of cfl in 3gal of soil, temps between 20 and 25, humidity I can't get lower than 63% and harvesting after 20% amber trichromes, flushed 10 days or so. Drying for 4 days in 70% humidity then paper bag for a day and curing in jars. Any ideas? Cheers.
  20. Hi, I just took the plunge and purchased one of these <spam removed> Normally I hang my light using 2 easy rollers but bit worried about hanging this using those. It's quite heavy. Can anyone suggest a better way of hanging to ensure its sturdy. This is to be hung in a 1x1x2 Budbox. Thanks
  21. High again guys, My yoyo light hangers just arrived, and considering how simple the idea of them is I'm thinking it's probably just me being retarded... When I pull the black string to the required length, then tighten the bolt again - the black string will still retract? As my reflector hasn't arrived yet I can't test them with it.. The pack came with no instructions, 2 screw in hooks and 2 little hook/bolt's presumably for attaching to the roof and reflector.. Anyone else had this issue? I've maybe been sent faulty ones?
  22. Ok so I've decided to get a room going for my own personal use I'll be using soil and I'm just looking for some help and info, I've got some mates who grow an have offered advice but also I'd like to get an outside opinion on this. I've got myself a walkin closet in my main bedroom I'll attach a pic, it's 5ftx3ft with a door for entry, I've got a lighting unit which is a 400w adjust a wing and a 8" Rhino filter from my brother. I need to know what's the best extractor to put with this. Also I was thinking of running the duckt pipe into the attic above an putting the fan up in there for the outtake? I'll give more details after ive had some help from what seems to be a great forum. Thanx for reading people. O this room is now empty

  24. Hi all. This gonna be my first grow, Im gona use a 250w Dual Agro CFL (6400k/2700k) with a CFL reflector from the top of the box. For the side, im gona use 4x20w cheap 6400k CFL for veg and 4x20w 2700k for flowering. The box size is 40x80x200 I want grow 2 or 3 plants. this lightning system could work?
  25. Hi Guys Sorry if I'm posting to many threads but help My Big Buddah cheese plants have reached the top of my tent, we'll the lights so I've been reading all day and I've bent the tops of the plants in-between the nodes so their at 90 degrees. They are about two weeks into flower and wondering if it is going to affect the main top cola bud production? I'm not new to growing well I've grown for a few years but only just experimenting more with my lady's and first time my plants have stretched that heigh into my light as Last time I just bought a new bigger tent lmao
