Transferring Compot to S/H

[sailor]

All of my S/H plants are doing great and I am considering giving a compot of slippers a shot. (I've never tried a compot with traditional media either). I just can't quite get my head around the best way to go directly from compot to S/H. I'm thinking of transferring all of the compot plants to a 9"w x 12"l x 6"h rectangular container, with S/H holes of course. The shape is very space efficient and would lend itself really well to a plastic dome that would allow me to keep the humidity high.

I am exploring a similar technique for starting my Spring tomato seeds next month. Sprout the seeds on rockwool until about 1" tall and then move to a S/H "compot" tray.

Thoughts? Advice?

Thanks - Ed
