Try filling in your profile and give us a clue as to how you are growing

Owd

ok im gonna try and do that altho thought i was in non organic compost folrum will go an attempt this profile

ok ive filled in my profile dont ave the set up some u guys got but hey it works ty people profile done geez i do hope feds arnt watchin

Can you tell us how you've been potting up your plants please? Also, how old are they and at what size? What is your watering regime? I know all these questions may seem tedious, but honestly we cannot help or diagnose your problem without getting a very full picture of what the score is in your grow. And I'm afraid we also need to know what your max/min temps are, as well as your RH. And some info about the size of your grow and how it is ventilated would also be essential for a true diagnosis.
Bear with us, and answer as many questions as you can. As we get the full gen, so we'll begin to have some helpful ideas for you

ok i dont know wat rh is i am very much a learner
i ave just discovered i need more air i only ave a small desk top fan plz dont laff my nl is about2 1/2 - 3 ft my shiva is about 2 ft i water probably everyother day at the moment bout two to three pints soak the soil n ave hols for drainage to flow outwhich is very little my pots are size says d43 h 32.5 cm ok im guessing it not spidermite or you wud ave said this straight away tis only a few leaves that look unhealthy ive fed once with tomorite at 7ml per 6 pints they needed feedint but only like feeding when they flowering which i am about to do they look ok so phew avnt damaged then am always woried bout feeding cause i killed a few b4 feedin when they didnt need it this my 3rd crop

Right, well I did not really understand a word of that, but here goes:
RH = Relative Humidity. You need a temp/Rh metre in your grow room. They're very cheap and can be obtained from the UK420 shop.
Watering - it sounds like you've drastically overwatered your plants. You should not need to water more frequently than every 3 or 4 days at the most. You should water your plants until you seen runoff at the bottm. Leave the run-off for half an hour. If its still there then, throw it away. If the plant has reabsorbed it, give more water until run-through appears again. Repeat the half hour wait etc. Cannabis needs a dry/wet regime to grow properly. Keeping it wet at all times is very bad practice and risks rotting the plant's roots.

How many smaller stages did you go through whilst potting up? The pots you're in sound quite big - or did you start the plants off in the big pot?

As to more air - how big is your room? How is it ventilated? You will need serious fans, not little piddling things. A pair of RVK inlines are what is needed. One to extract via a carbon filter, and one (just a tad smaller) to inject fresh air. Then you need an oscillating fan to disturb the air within your grow area. Ventialtion is just as important as water and light. Too many people try and get by with inferior venting, but its not worth it - honsestly ventialtion is critical to your growing success.

right i potted my plants clones in seedling trays individual ones
then a bigger size then buckets now my big pots ready flowering ok ive ordered a bigger fan and ill go check out the shop is it worth buying so much equipment for two lil plants?
and room is tite?
ty for ya help tho

and the water drys up pretty quick with the lite on in there when i flower n switch to 12 12 they dont need so much water theres neva much drainage

hey up mate .look fella its really important that youv got the right gear to grow weed. i no youv only got 2lil plants but all your doing is waseting money on leccy if you havnt got the right gear to grow it properly. Dont get me wrong mucka we were all newbies at growing once but my advice to you is get your grow room up an running to perfection B4you get your plants. An if it takes 3mth to that so be it but you'll be a very happy chappy wen the time comes to reap your rewards leepy ps welcome to our wonderful site

How big is your growroom? This will effect your choice of fans. You need inline RVK's by the way, with ducting etc

I think you should reasearch thoroughly the whole issue of watering. looks like you still have not quite understood the idea of wet/dry, if you're watering every other day.

Is it worth buying equipment? Yes, if you want to grow serious cannabis. If you just want to grow ropeweed, do it any way you please!

By the way, your plants may well need more water in 12/12 as their needs are more demanding on the whole system; which is why it is important you learn to water correctly and to understand when a plant is truly thirsty.


What are you asking? I do not understand.

my room is only about 2m by 1m not very big at all and a sloping roof dont help

That's fekkin huge compared to mine M8. I grow in a wardrobe that is 2Ft x 1Ft 10Ins!!
Your room is going to take quite a lot of vetilation and lighting. To light 2 SqM is no mean task; at a minimum of 50W per Sq Ft, your area is going to take 1800W. Minimum. Venting will require some heavy kit too, a 10 incher to extract and a 6 incher to bring air in, I would say, as minimum requirements.
I would try and build something smaller to be honest. Seriously, unless you need to grow about 40 plants each time.

hmmm my weed is not that bad not the best out there but hey thats why im ere but i was lookin at carbon filters n they like 300 quid ok so im lookin at the rh meters temps etc yes sometimes they do need more water when they in flower in the bigger stages my weed is just small im sure i cud improbve this im sure the john innes will make a diff n when i order sum the gd feeds u got on this site wud an extractor fan do the same job as a carbo filter just aaswell?

i was under the impression it was 100 w per square meter? guess im wrong

and i can only just fit two plants in in flower tried three n it dint work to well u must flower smaller than me?

I have 4 plants in 2Ft x 1Ft10Ins M8, as you can see In my Diary, clickety click
In the space you've got, I would be growing around 35 - 45 plants, easy, maybe more. When I had a 1SqM tent, I had 15 - 20 plants in, with space enough to spare. All in 6.5L square pots, and all finishing at around 3 feet tall, or taller if sativas, and yielding between 1 and 2 ounces each, or maybe a bit more - it all depends on the strain being grown.

You can use 100W per SqFt, but its very hard to control the heat IME. 50W per SqFt is recommended as a low optimum; 75W is good, but again, heat can be a factor. In setting up a grow I would always start at 50W pre SqFt, then maybe increase as I develop the grow and learn what it needs and how the heat situation is being handled.

1mx2m=18sqft

So 50w/sqft=900w

So your choice really

2x400's would be fine but 2x600's would be better providing you can control temps

ok so i started in seed pots moved to a bigger size then buckets now my big pot ready for flowering so i dont ave to repot during flower which made sense to me i been in tha chat room getting sum pretty gd advice i been told to ask jools when he back bout a td160 fan i need ive also got a bigger oscilator on tha way and im gonna ave a word with my electrician mate bout another light thanx all so much for ya time ty

yer i needa temp measurer cant wait to try my new improved yield mmmm my moth is watering

If your room is 2x1m then a td160 aint big enough for the intake never mind the exhaust so not good advice i'm afraid

You will need at least a 6" out and a 5" in

Owd

Indeed.
MSLazy, I really think you should ponder building a smaller grow area within your available space, it would make your grow a much easier one to handle and get a grip on. Large grow spaces are, IME, more difficult to control. And as you are only growing 2 plants, you really don't need all that space IMHO.

I just wanted to comment on this. You will definately need a carbon filter and an extraction fan. You need the fan to extract the air through the carbon filter and prevent any smell from escaping and putting your grow at risk of being discovered.

It really is very important to contain the smells, you are asking to be busted otherwise

ok another lite is being sorted another 400 watt take my room to 800w my roof is slopped which makes growing more rather difficult my nl touches the ceiling at normal height i cant beleive i can get 30 40 plants in my lil room ok i guess im not gonna get away with a td160 so im looking pondering asking and still clue less can i start flowering then from bout a ft to end up bout three ft then? im thinkin smaller maybe be a better way for me? and i also ave an idea bout carbon filters but i dont wanna spend 300 any ideas? mslazy

Have a look in the 420 shop

here! budget filters.

ok thats a gd un i can neva find anything online 38 pound dont sound to bad doesnt ave fans tho that i can find

hmmm thinkin the 60 quid looks better n lasts longer than the single use ones i was told to get a 4 in intake fan n 6 in outlet fan does the rvk do the same thing anything in the shop?

do i need two rvks?
one for inlet one for outlet?

buts its all too technical the chat room is cool tho

eloooo anyone there give me a link on tha site for training my plants to keep small i cant find wat im looking for im gonna flower my babies smaller so any info surroundeing that will help ty sorry to be a pain

sea of green doesnt bring up anything

Maybe search for SCReen Of Green (SCROG)?
