Hello all! I am attempting to grow a Kaffir Lime Tree from seed. I am germinating 7 seeds right now wrapped in a wet, folded paper towel, enclosed in a ziplock bag. After 3 days, it appears that the roots are starting to pop out of most of the seeds. So it is time to drop these suckers into some soil pretty soon.

My question to you is: can I put them in a regular burpee self watering tray until they are ready for a larger container out in my greenhouse in a few months? The typical instructions I read on the Google machine says to sow them directly into a 4" pot. I don't have 4" pots, nor do I want to use these indoors b/c of space constraints.

Is there something about needing a deep container for the early stages of this lime tree that preclude me from using the normal seed starter trays?
