Another first grow - NLxBB

Well I started my first grow about a week ago. I had 5 northern lights x big bud seeds that i germinated, but only 3 sprouted. thats probably all i have room for anyways though. im using a bunch of cfls for the whole grow - 4 26w cools, 2 32 w cools and 1 42w warm. for soil, i mixed up some ocean forest (50%) perlite (30%) and vermiculite (20%). right now im using 24/0 light schedule. im thinkin about goin 18/6. i know there is a lot of debate as to which is better, what have you guys had success with? or does it matter. also, two of my plants are really leaning over. they are only a few days old, so will they straighten up or should i straighten them? well here they are. any suggestions/comments would be awesome. thanks

It could be a good idea to go 18/6 your tips look a little burnt or somthing. Giving the plants a rest or night time Is a good idea most say. Just like us they need some rest daily.

hey,
your setup sounds good. I would say, that u should do 18/6. In my opinion it doesn't really makes any difference. 24/0 or 18/6. I have few grow/flowering rooms and there are 24/0 in one of them, 18/6 in the other and 12/12 in the third one... and the reason I have 24/0 is just cuz I don't have a third timer LMAO
what's up with ventilation system? is there any air circulation in your growroom?
don't straighten up your seedlings. they gonna do it themselves. in fact, be careful with your plants. they easy to damage while they so small. keep your CFL's as close as possible. then your plants will grow bushy and short. I guess 4-5 inches is perfect distance.
good luck.

for ventilation i have a fan on top pullin air and two vent holes on bottom. there are two real small fans inside to push the air around. but it stays around 87 deg with 5 of 7 lights on and door cracked. so i think im gonna stick a more powerful fan in one of the vent holes. should that be good enough. its only about 12 ft3. thanks for the help

temps should stay around 76-78 (25 deg C) right? or should it be warmer during this stage? thanks

alright. i got another fan and my temps are around 80-82. hope thats alright. dont know how to keep it any cooler without doin some ghetto cooling thing. how are they lookin so far? they are about 8-10 days old. are they small? they seem pretty small to me but i dont really know. thanks

Cooler temps can help premote female traits, so try to get the temps down.

Nothing helps promote the sex of a plant, if it's a male then it was planned to be a male the minute it germinated. The only thing that lowering the temps could do (which needs to be done CJ) is help keep your plants alive and right now that needs to be done because those plants look unhappy. Also does that say 24% for humidity? :eek: raise that humidity up to some where around 60%-65%. I'm just saying that incase that is your humidity that I see.

While it's true that Cannabis seeds do have a genetic "destiny", so to speak, enviromental condtions can alter the sex of your plants.

orangeman. what about the plants makes them look unhappy? color, size? im havin a hell of a time tryin to keep the temps down. i cant vent or draw from outside, but i do try to keep my windows open for fresh air. but that drops the humidity (humidity is around 23% where i live). so i guess i need a humidifier? any suggestions? thanks guys
