I dropped this 5 pack of Zombie Kush 5 days ago. I soaked the rockwool cubes for 24 hrs in dechlorinated filtered water before I placed the seeds in them. One of the little ladies blew right out of her cube lol. I cut a piece of rockwool off a new cube and covered up her roots. All 5 are happy and healthy.
These are under 2 125W 6400K CFLs.
