Hi everyone, I want to vegg in 4" rockwool, what happens when the roots stick out of the bottom of the rockwool? Do they just sit on the plastic I have the rockwool on, wouldnt that harm them? I do not want to stack cubes, or use any other medium. Just the 4" rockwool. I will move them into...

As above, anyone grown using CFLS? the red spectrum 250 watt ones i mean

From what i have learnt, if you top at the 16th or 18th node, the auxins of the plant [these are some form of growth hormone] will be redistributed to the lower nodes, but it could be any of the 14 or so nodes below. You will get colas but one of them will be the main cola. It's not the same as...

UB, awesome thread! When you say no special advantage to doing 2 colas rather than 4, does this apply vice versa too? Why do you choose to do 4 instead of 2? just cos it looks cooler :)

Dude you mean just tying my four tops down with some string? what will that do? Will it make those tops grow upright so it looks like yours? I plan to transplant into the 11ltr pot and then put them in flower right away, i dont have room for an 11ltr pot in my veg box. Can I wait til then to tie...

My friend grows CFLs with great results like yours, it's brilliant man! So yeh I'll probably leave it at least another week before flowering. I'd be happy to get those results like yours... thanks mate.

So i am gonna have to transplant into a bigger pot, i have an 11ltr i can move it into. I think that should be ok, what kind of yields did you get with the 7.5ltr pots? I have a hps for flowering btw.

That lime green colour is the same everywhere... I am pretty sure it was all dark green before, but who can remember what anything was like a week ago :)

Those look awesome man, congratulations! I wish mine look like that at the end, i'd be very happy! What size pots do you keep those in? is that coco? I was wondering if i could flower in 5 litre pots cos i have them in that size now and i dont fancy transplanting.

Excellent, thanks mate! Well it's exactly 3 weeks old now from seed and it's vegging under cfl lighting. I plan on flowering in a week or so under a hps. So, you reckon it will survive, cool :) At which node do you usually top? i employed uncle ben's topping technique [badly]... I had another...

no help???? :(

Shit sry... i added the pics in the original post. Yeh I think i have over done the stress factor... take a look pls, thanks

Hi, A week ago I topped my plant at the second true node. By mistake I cut off one of the tiny side branches by the stem in the process, so instead of growing back 4 tops it started growing 3 :( I decided to top again at the node below. The result is in the pics taken today. It only has 4...

Cheers all! Gave some more Veg ferts mixed with bloom ferts, havent seen any increase in yellowing. Should be ok till the finish now hope hope hope! :)

Without an EC meter I was giving 7ml Ionic Bloom per litre, as it says on the bottle. But it also says the EC should be 1.5 for Passive Hydro systems. I checked the Ec and it was 2.5ms. So I have brought it down to 1.5ms, I have taken into account my tap water EC which is 0.6ms. So basically, I...

When lights come on i will check properly for mites but I am quite positive it is not that sort of problem. Still one can never be sure.

Thanks for everyones replies! The N deficiency seems most liekly. Yes it is a bit early for it though. I gave it some veg ferts 2 nights ago and I have not seen any further yellowing. I cut the bloom nutes dosage about a week ago, because I started using an EC meter. So now it has EC and PH...

This plant has been grown 12/12 from seed since 1 month and 5 days ago. It showed female hairs about 2 to 3 weeks ago. Yellow leaves are now at the bottom and seemed to be moving up through the plant. I gave it some formulex for nitrogen yesterday, though it is vegging nute - incase it was a...

Deos anybody use Cellmax Growcubes? I would like to discuss watering and various other issues regarding them. Thanks.

In order to avoid nutrient and salt build ups in the bottom of a pot I have been advised to flush weekly with PH'd water until water drains from the holes at the bottom of the pot. I only water once or twice a week as it is, and I never water enough for drainage to occur. I think if I watered...
