If you wanna grow the 'dro you need to grow hyDRO.
Do It! eff soil IMO!
Get yourself a 600w instead of a 400w you will be wayyyyy happier!
grow from seed in coco. I mix mine with hydroton. water by hand the way you will with soil. But you use nutrients in your water every time you water because the coco has no nutrients in it the way soil does.
veg your plants for 1 month then switch to 12/12.
just take a look at these:
first is a sugar black rose seed from the attitude
second is an og kush seed i got from a friend of mine.
both took about 3 months from seed to harvest.
used ionic bloom and boost in coco and watered by hand.
under a 600w.
The SBR gave me about an 1 1/2 z finishing at 20" tall, the og gave me about 1 3/4 z finishing about 24".
I had 4 other plants that crop as well.
KISS-keep it simple stoner
