And what "Magical" method did you use to get the three to germinate?
Your experience sounds like my attempt at Aero. Should have used seeds I knew would be okay. But I wasted my Sky Wardens. Started with 6, 5 sprouted. Out of the five, 3 were male (one of which grew to 4 feet while the others were less than 2 - pulled it to collect pollen.). Put it in a DWC setup in my wardrobe..... it died, or I should say I killed it. Don't know how, but I did. Then the two females, left in the aero setup died as well. Absolutely nothing changed, so I have no idea why they did okay in veg and just simply died in flower. Needless to say, I am going back to coco for the time being!
