Cab V2 - Rnd 1.1 - Critical

Put (Barney's Farm - Critical Kush) seed in paper towel/ziplock bag, in seedling tray on top of heating mat set to 81F. Seed cracked open and tiny root after 3 days. Moving to rockwool shortly, then into DWC once roots appear through rockwool. Going to grow alongside Fruit Punch clone! ------ SO, after 3 days in the rockwool, no sprout. Opened it to see that the root has rotted off. No idea why, but it was in a domed seedling tray on a heat mat set to 82f. Am germinating seeds for my indoor garden right now, and most of those popped with no problems. Hoping the seed was just a dud - have another soaking in water now. The second seed (Barney's Farm - Critical Kush) cracked open after 2 days, tiny root visible but not out, placed in paper towel. 4 days later, still no change, root rotted off. so confused. ------- Trying Royal Queen Seeds - Critical next. Placed in glass of water. wish me luck. After 2 days in water, no change. Put in rockwool - after 3 days, we have a sprout!!
