All sank, both contest-ers had nubs poking out. Don't know if having other junk in the pic is OK, but here's my nursery tent. 2HLG-65, a 4" in-line duct fan for an exhaust and a couple of muffin fans to move air. I have a heat mat on the outside of the tent under where the dome is
I'll only use that until they open up well
In addition to the 2 AC × Adub (contest), I had some other fems that I either haven't tried yet, or want more of.
GMO Cake , SD X AC , GG X DD, Lemon Tree S1
And since we're talking methods, I settled on this after trying lots of different methods. The cup has regulear soil for about 2/3, then the top layer is seed-starter soil that is much finer.
Clear cup split for drainage. Easy to check moisture content and roots. Opens like a clamshell for easy re-pot. Dark cup, no holes for the outside.
Don't need drainage yet, but when they do get soaked you can stick a rock or something in the bottom of the cup to raise the clear one.
