If you are using peat moss, you need lime in the mix. Peat moss is wicked acidic. Lime will take care of that.
D'Oh, good thing I asked! I'll skip the peat moss then, and use the left-over potting soil I already have & mix in perlite & vermiculite. Fourth or fifth grow and I find I still need to improvise

BTW the grow cab is a converted Home depot wardrobe, the floor space is just under 2 foot square, but height-wise I have a good 5' for the plants to grow!

Hopefully 2 litre pots will be...adequate!
