What's the best way to get the seedlings out of the tray and into the ground? Is there a common tool used? I've only ever used trays with much larger cells, so transferring the seedlings was easy with just my fingers.
We personally use a tiny screw driver or widger while gently pulling on the seedling. Just our method!
Are your 1020 EXTRA strength trays made of #5 plastic or #6 plastic?
Our 1020 extra strength trays are made of #5 PP and are food safe and BPA free!
I need bulk peat plugs to fill trays as well
We haven't used peat plugs ourselves so I am not exactly sure which brand(s) would fit our trays. I'd reccommend maybe just purchasing a single tray and then experimenting a bit before buying more to see what best suites your needs. :)
What is the actual drain hole size and shape? Can I use a dibble board to pop the plugs loose for transplanting?
The drain hole size is 1/4". We are working on our own plug popper to work with these but that is yet to come.
