View attachment 1466061hay GK I just started my first grow with cfls and i am using 3 of them on one baby now shes about 2 weeks old and i got all of the lights above them because my setup is in an old computer shell what do you think would be good for me to do get some more lights for the sides? and can you bud them with cfls? please hit me back i just started using this sight because my friend B16 told me about it i would like to show you a pic of what i am working with this was like 5 days ago haha:leaf:

hey king,
you can keep adding lights as you wish, but remember more lights = more heat.
try to reflect the light around inside the computer shell with mylar or similar
with cfl's you want the foliage as close as possible to the actual bulb without it touching

i wouldnt recommend cfl's for flowering because the buds are usually more airy, less dense because they are stretching alot for the light.... but as far as potency is concerned, there's nothing lost :)

I grow and harvest w/nothing but CFLs, large and small. As far as bud beening airy is bs.. I move my CFLs around alot during flowering. Last grow I was burning actual wattage btw, +1200 watts, over +70,000 lumen. All my bud's nuggest hard, tasty and kicks-butt, check my grow journal. I will always grow w/CFLs

I was at lowe's the other night looking at the lights and they have this light that screws into a standard base but has three articulated (flexible) arms for lights! like 20 bucks but it's capital not nutes or power! So like you could literally have three bulbs or six if you use doublers per one of these using cfl's!

You can tell if the CFL is to close by the plants leaf tips, they will dry and brown abit, just move it back another inch. I try to get as close as 2-3 inches, but any closer the heat may burn the folage. Now when I got the bud or cola's close to the CFL, they just get fatter and fatter. Move your CFLs during flowering each day, trust me, it will make a hell of a difference....

So I'm reading to switch the light color between veg and flowering, that makes sense but is there any harm in burning both kinds of light the whole time? I.E. I have 6 27w 6500K bulbs and 4 42w 2700K lights. I was originally going to use the 6500s for just veg and then switch to only 2700 for flowering. But my question is can I just light all 10 bulbs without suffering any ill effect in either stage?

Specifics: 3 plants in a 4x2x6 space, evenly distributed bulbs. Soil grow. Standard growing, no Scrog or SOG yet. Probably Raspberry Cough if the strain makes much of a difference.

And question two: reading this I assume it is but to double check, is that enough light?

Wow. Read the whole thing....feel knowledgable. :) 2-1 ratio is. How you wanna mix your lights hardwire. 2-1 6500 for veg and 2-1 2700 for flower

Sorry to come out of nowhere but i have a question that i cant find the answer to anywhere...im growing a few different strands of autos in my new grow tent using cfl and my room is starting to get hot(not cause the cfl just the temp outside). would putting on my AC in my room kill my plants or does my tent keep the heat.???

try it. keep the heat? not sure what that means, i think what you mean is, if the room my tent is in has an air cond, will the tent exchange the hotter air inside w the conditioned air outside the tent... is that right? the answer to the tent excange is quite simple, a fan is very important. my friend when i tell u that 75 degrees should be the temp that u can acheive, i am telling no lies. then YOU control the enviro not the otherway around. I think your ac + a 120 cfm fan will do for a start and you can see if it makes a diff.. let me kno

How many plants in 3 litre pots would you have under a 250w red sped in a reflector and 250w blue spec cfl in the side? How many weeks would you veg for as well?

with the 250w CFl you're only gettin at the max 20,000 lumens so 40k 10k per plant keep the light about 5-6 inches from the top. you could do 4. veg till 18' then flower

Agreed, I use CFL's and solid white 5 gallon buckets for the sake of light retention/reflection all around the babies. Seems to do much better than the same amount of light hanging all around in a larger grow area or room. Light retention is one of MY key factors with cfl's and they work great for small enclosures. Depending upon your setup, the buckets give great reflection and allow for the vertical movement needed with light proximity... if needed you could probably cut off the bottom of a bucket and use it (the bucket) as a light reflector in the case of smaller vegging plants. What can I say, I love buckets and cfl's lol. When using buckets make sure you coat the outside with something much darker to keep the light from leaking through.

I use reflectors on my larger spiral CFLs, but for the most part cuz I have a small grow closet, the flat white painted walls are really my CFL reflective fixture. I have many 23watt, 42watt and 55watt CFLs on a cfl splitter w/o any reflector fixture and I get awesome results anyway. Moving the lights each day really helps as well, getting the lumens as close as possible to those colas.....

I'm currently burning 1280watts, 83,000 lumen in a grow closet of 12 sqft for 4 feminized plants, 3 Colombian Gold, 1 Blue Widow using a diy aero-hydro grow set-up, this grow is my 1st re-grow attempt, about a week or so from the cut.....

What this guys is saying, without composing a complete idea - is that you have to have lights for the UNDERGROWTH. Growing by CFL's is tricky - they have a 360 degree light radius so its very hard to FOCUS the light on certain areas. What this man is telling you all to do, is to make sure you have lights not only above the plant for height growth, but also on the sides or the plant will not be as healthy as it could be.
