I have 7 plants total in party cups. They are 7 day old with 1 set of true leaves. I have a 26watt daylight cfl for each of them but wondering should I cut all the bullshit and flip the switch to my 400 watter..

what does posts have to do with anything .. its common sense .. does the sun hurt seedlings use your brain man ... if you are not a moron and dont have your light to close you will be fine .. just because i dont play on the internet all day doesnt mean i cant grow .. take the advice or dont ..

Hey dude its all good.
Im using a 400watt an my babies are like 1 week
4 days old..An its goin ok. Just keep it 2 ft away,
then lower it a lil till you think it'll hurt the plants.
I had it 2 ft then i lowered to a ft or so, just put ur
hand above ur seedling, if its not to hot ur good.
Also try n have a fan (at least 1) blowing on ur light to
keep it cool. Good luck bro

Be afraid, be very afraid.

Heat issue. I killed all my seedlings with too much head. I had a 250 watt MH. Part of the problem, I had them in a tool shed late summer and it got very hot. The heat will kill seedlings. So, if you hang the 400 watt high and you keep the temps down, you should be okay. Just watch out for the heat. I learned the hard way.

FirstTimeGrowGuy - Like I said, thanks for the help bro.. +rep

Everyone else - I don't mean to say you dont know anything, but I rather get advice from someone who participates in the same forum as me.. Not someone that may accidentally fuck my plants up!:bigjoint:

I just lowered my cool-tube from 3 feet to 2 feet. Im going to leave it on them all night and see how they look in the morning.

Temps are 83/84F
Humidity is low <40

I want to lower it some more but am going to wait til they develop their second set of leaves:bigjoint:

Thanks guys

I use a 600w HPS light from day one and have no problems. Just make sure you keep it at least 36" from the tops of your plants for the first 2-3 weeks, and keep an eye on the temp at the canopy, keeping it under 80F.
