    they are healthy looking plants. look mostly indica. heres the thing grow veggie mode till they are a foot tall depends on strain and everything but you are almost there. then when you flower the plant can double and sometimes triple in height during the flowering process. so if you stretch it in veggie mode when you flower it wont support itself and you will have a battle of keeping the plant upright and its not easy even if you have a fan stretching it will cause more harm then good. how tall are your plants now?

    thanks for replying. umm the one on the left is about 3 1/2 weeks old and its like 6in tall and the other on on the right is 6in also. and about flowering it. i have kinda small grow space and if it doubles and somtimes triples in size i can fit a 3 foot tall plant.

    The longer you leave it in veg, the taller it will gorw without streatching. When it is one foot tall then start to flower. I prefer to let them get a bit older as then they are mature when you start to flower. Plants would normally be mature when they flower as opposed to force flowering. Indica plants will normally stay a lot shorter. I have some that are 6 months old now and they are about 2 feet. They are my moms, so I just keep them in veg and clone them. Even with CFLs they will grow, normally they would strecth more under CFLs. What is your light cycle set to? If it is a 24 hours light and no darkness, then they will also not stretch as much. If you have it on an 18/6 schedule they will stretcha little more. Why do you want to stretch them anyways? Aside from not being able to hold themselves up when they bud, it will not increase yield, and infact due to the stress they suffer from stretching to search for light, it can actually decrease yield.

    I would push the lights up a couple inches and watch them take off. Outside the sun isn't laying on top of plants thats why they get so big and bushy and tall.

    Don't worry about you'r not being as tall as everyone elses. Don't put your CFLs higher. The reason the sun is not right up on the plants is the planet would burn. The sun produces about 5000 Lumens per square foot and it is constant from the tops of the trees to the bottom. It is already so dispersed by the time the light reaches here a few extra meters doesn't matter. With articifial lights the Lumen output drops exponentially. there is a reason everyone keeps their lights as close as they can, it's for maximum light on theplants. CFLs are not the best lights in the world, so moving them further away if you don't have to is not a good idea. Taller plants are not necessarily better. I grow a lot of my plants very short. I start my clones flowering at about 6" to 8" tall in a SOG. You'r plant will get a lot bigger in flowering. Don't rush it, just enjoy the growing experience.

    I see your containers are not very large, are there any roots coming out of the bottom holes yet? It is possible that you are root bound or close too. If you run out of space for roots to expand you will have to water more often and it will stunt the growth of plants. You can always move to larger pots, if wouldn't hurt to do that too.

    Why would you want the plant to be more taller if it is growing a nice way,You will regret it my friend if you higher the lights when it comes to harvest.The closer you can get the internode's on the plant the higher the yeild when the internodes join you will end up with one big cola.I think that the lights that you may be useing is not strong enougth for the plant.I say this because of the lenth of time that you have been growing and the size of the plant.I would also top the plant this will give you 2 colas instead of the one.

    I think your root bound....I have some clones that weren't growing very tall either so I transplanted to bigger pots and they took off...don't put your CFLs anymore than 6 inches away from your plants.

    thanks guys you are all putting good ideas in my head. i dont think its the lights. i grow under two 42w (150w) and five 26w (100w) cfls. i think the older one is just a weird strain and seed. yeah no roots really coming out the bottom yet. how will i know if it is root bound. what are the sighns of root bound plants? here is a little pic of my lights and plants while lights were off.

    6" seems a lot especially with CFLs. Try about 2" aways. Just far enough so the plants don't burn is Perfect.

    Usually you will see the roots coming out the bottom holes a little. You can always take the plant carefully out the container to check. At this point in tim you might be root bound. It is a very common thing to happen. These plants grow extremelly fast and a lot of people get root bound with out knowing it. If you are not root bound and you plant into a larger container it is okay and won't hurt. I like to get my plant root bound before I transplant. I veg mine for a lot longer than most people and like to have a tight root ball before I transplant, as bad as being root bound sounds, I found out a long time agon that in the long run, especially if you are keeping plants for a long time, actually helps. I know this sounds strange and yes it does stress the plant a bit, but when you get root bound, you develop a very complex root system. Being root bound is bad if you are just going to veg and flower asap like most people, but again, i don't. It does actually make the plant stronger in the long run when you get just slightly root bound before transplant.

    Again just go to a larger container and it can't hurt. It you want a better light, try to get some T5 High Outputs. I used to 2 four foot T5HO for veging and they work great, I use 6 three foot T5HOs now and 8X for flowering. It's a great setup. I use Sunblaster High output T5s.

    Nice little set-up. Defcon is right and I agree with him. I keep my floro's very close to the plant (2-6 inches), I never move them anymore than 6 in. away from them.

    I definitly believe your rootbound. try transplanting.

    Tell us how you made out.

    hello.

    my babys are 17 days old. they look pretty. but the first is 9 cm tall and the second is 7 cm tall. i transplanted the first from the party cup it was two days ago. and yesterday the second. they grew with a 105 watt cfl 6500k. and today i turned on two 85w cfl 2700k. the three bulbs have 13750 lumens output and are about 3-5 inches away from the babys. are they too short? the pots i transplanted them are 3 gallons and maybe their final pot cause of limited space. strains are samsara alquimista for the taller and samsara spicy white devil for the shorter.. temps are about 25-29 celcius. 24 hour lights on

    tell me what to you think.. especially for the height issue... thank you!
