ok where to start? i guess ill list my equipment. 2x4 flood table with 2 air stones, lumatek 600 with mh/hps bulbs. bluelab guardian trimeter, air cooled hood and much more! ive killed 20 sweettooth seedlings and 10 ak 48s. i was really bummed when i killed the first 20 st seedlings so after more research i contitioned the rockwool by rinsing it for a looong time then soking it in ph'ed water over night. i germed seeds in paper towel with 100% sucess then put them into the cubes then into a dome with a seedling mat. im thinking maybe i transfered them into my system to quick? the roots were just starting to show threw the bottom. but when i got home from work they all fell over help me RIU!!!!!
