Do cfl lights have to be close to the plants always?

This trainwreck seedling has been under two CFL light since sprouting, on a 24 hr light schedule. It's been about three weeks and I'm now putting it under a 250 watt hps light with a schedule of 18/6. I had them in a twenty gallon storage bin with a lid, I had the CFLs ran through the top of the lid so they Hung down over them. My lights wer e always only about six or seven inches from the plants, I had four or five other seedlings in there. I was not expecting to have these results, I didn't even expect the seeds to even sprout, they did, then they took off. I'm very impressed so I think I might acquire some more seeds somehow, and start more little monsters.

I have never burn a plant with a cfl inless it was touching a leaf . From the picture you posted , that didstance is just about right. Are you sure it is not nute burn or somthing? Or heat stress?

Just back off the lights and ''suck'' the air out. Its ok to have a fan moving air, but not right at the plant,

Well Well Well.... Where the hell you been? How ya been?

Ga.

This set up was simple and cheap and i gotta very nice grow for my first indoor grow. I like using CFL's ya just need to keep an eye on the plants so they dont grow into the lights but ya need em close, but not touching them. And like i said moving air is good, but sucking the heat out gets er done man. I put the lights above then broke down card board box's planted white and just kept them tight around the plants with a cut out for a small fan to suck out heat.

I hope this helps......



LMAO, I posted, looked up and couldn't stop laughing. Iv been in snooping around, but gotta move soon so lately been busy looking for a new place to live. That freak i was living with finally moved out, lost my house, but gained my life back, lol. Good to hear/see ya, il be around,


Catch ya later bro

I backed the lights up and added a good intake , the plant is growing nicely now. The soil seems ok I'm buying fox farms to re-pot though. I think the heat built up around the light because I didn't have an intake and it burned a whole leaf off and the round leaves. It happened within a hour so I know it was the lights.[attachment=o280413]

Looks ok to me, but dont bring air in if your not taking the ''hot'' air out, thats what ya need. And the little round leaf is just not needed anymore, it feeds the seedling. Just fill the cup with roots before re potting, see my Sig for a easy re pot tip, it may help, there are pic's and real time as you see the plant lift its leaves right up after getting attacked by bugs. Harvest was nice as i finished it inside.

Intake isn't going to take heat out, only give fresh air to your plant. If anything put your intake at the bottom and pull the heat from the top. And you only need one or two CFL's for that plant at this time. More will only stress it out.

Thanks for the info. The fan is a cpu fan I have three One at the bottom blowing in, and two inside dryer ducts at the top of the box adjustable. The box is an armoire. I have 12 lights on three plants.
