Just be careful of your runoff. The tray will fill a bit quicker.

I suppose you could use rocks for the FINAL pot you are going to use, BUT, as I learned, these rocks have a certain pH. Being at the bottom of your medium, it wont matter as much, but the roots will bind there and feed around them, thus creating maybe a problem you dont need.
Hehe, I thought rocks would be a problem if I had to transplant but I planted the seeds directly in 13L pots.Sometimes transplanting stops growth for some days (shock) and I had limited time for veggin, so, since I've got even the trace elements to feed them, I chose not to transplant.Rocks help with the drainage and I use them with every plant I grow.

Anyway something came up and I had to leave.I'm in my hometown now.I will update on Monday, I should have the ph kit until then.:jointsmile:
