The 1.5's don't fit in those holes on the tray rack, unless you really squoosh and force them. I think it's made more for those split cubes.Correction, you place domes until seeds sprout, as soon as seedlings they come off so technically not running domes on seedlings.
I did read your thread few days ago, I did too for rock wool germination it dries too quickly sometimes.
Mega impressed with the rock wool cube holder tray, yet to see anyone use it properly though lol. I loved rock wool for germination, place seed exactly the same way in each, barely cover, one shake and some. Soil is a curse to me thinking of all the cool stuff I've run![]()
It still works to keep them off the bottom of the tray though (where they'd be closer to the heat mat, than I prefer). Allowing the roots to dangle, also keeps them from bending at 90 and getting damaged from being under the cube. Water can be left in the green tray to keep dangling roots from dying out. To feed/water, I dunk the cubes in a 1gal pitcher of nutrient solution that's 300-400ppm. I was 100% above wool within 72hrs the last run when I used this method. All survived.
