As far as conditioning, I ran water through em first before I put the seedlings in them. I know thas prolly not the conditioning you're mentioning though. And I hear ya, but i've also seen others post their possible problems in the section that they're growing in, thas why i did that. But cool, i'll try that next time.

Since u said rockwool isnt the best, what do you suggest as a good starting medium for going into a DWC? Thanx
