A moment of your time if you will

Wow! I was going to say that they looked stretched - move the light closer! But it looks like everybody else already said that.

So, I will just add this: Make a little "reflective wall" around them (to hold the light in). It may seem obviouse, but the more light that leaks out and lights up the room means that less light is going to your plants. Don't over water or over feed - read up on this, you will be glad you did (these are the two most common mistakes made by beginners).

You can use 400watt system from start to finish. Start with a metal halide. I kept mine about 20 inches away, but you can adjust it. You'll know if she is getting too hot. I believe you can do this with a 600watt system also. I think it's 36". I also use 2 2' shop lights with grow bulbs in and have them mounted vertical and rotate the plant every day for even lighting. Just a thought

Thanks I built a little reflective wall out of the whitest thing i had to hand, which was an essay i wrote last year about the social effects of convergant media technologies. yay.

I think it looks better, i will think about getting some of that plastic stuff, and putting the bigger light in when npower get rid of the pre pay meter, cause it costs a fortune!

wow, what a response, thanks everybody.... some good advice there, i'm getting the feeling i should moove the light a bit closer in!

I will do that, I've got a 600w HPS and 600w MH but they are hot and i'm sure would burn the plants from over a foot away. This light is only noticeably warm on your hand till about 3 inches away, which is about where it is but the leaves are starting to curl slihtly which i think means they are getting too hot?

I did just water, but perhaps i am overwatering, i shall cut down!

I think the plants are about 10 days older give or take.


Thanks again everybody

put the hps on them. just get a small fan and keep blowing on the light. keep the hps approx 18 inches above them.
good ventilation is key to a good crop.

Yeah, i have to get a new fan, i had one that i got for 8 quid from a guy at the rag market, and it burnt out in about 3 days! no good! I will get new one, would you say it is necessary that i have a fan removing air too? There is a hole in the ceeling directly above the plants that goes to the attic, cause the air up there is cooler it creates a bit of circulation, i kind of hoped that would suffice

the light is more than enough for now...
like everybody said, move it closer!! and when it's time to transplant to bigger pots, bury the streched stem a little.
i've gone all the way from seed with just cfls, and i've just cut down my baby today. i think the results are dissent.
Keep on, and let us know how they're doing!

So its a few days later, i lowered the light some and made the sides of my grow area more reflective, also replaced the fan with one that works. They are grow more out than up now, which is good. But still slowly, i guess that this is because there is not as much light as there could be??? Also i was wondering about humidity, what effect does low or high humidity have on plants?? Thanks Al

As far as i know, humidity prevents plants from losing too much water (plants try to decrease the leaf surface area to lower the water loss which also reduces the photosynthetic leaf area). Humidity also helps to form strong roots, which is essential for seedlings.

A relatively low humidity is especially good in flowering stage, for healthy and potent flowers. Molds and other fungi are less active at low humidity, lower humidity during flowering stage ensures healthy buds with no mold or anything. Also, plants are said to secrete more resin to decrease water loss when the environment is low in humidity.

The ideal humidity levels (according to what i could sum up from the internet):

Germination Stage: 90-100%
Seedling Stage: 70-90%
Vegetative Stage: 60-70%
Flowering Stage: 40-60%

they're looking good!!!
be careful though, with the watering schedule!! You don't want to overwater...

Cheers man...

They look quite nice. If that CFL is the only one you have, i guess it's now time to add some more of that or switch to those 600W HIDs. Be very careful with the HIDs though, you saw what happened to my little ones when i switched from CFLs to 150W HIDs. Put the HIDs at least two feet away at first, then gradually go closer up to 15-20 inches.

Good luck.
