I noticed on the manufactured Humidity Domes the Tray they supply has groves in them such as this one.
Is it really necessary to have something like these grooves to keep the rockwool from sitting flush with the bottom of the tray?
I was planing on making this design for 5 germed seeds but didnt know if it really mattered about the groves in the bottom tray
