Home made wooden grow boxes
I'm looking to make custom wooden grow boxes.
My usages are indoor growing of veggies...lettuce, Kale & spinach.
I've done a little research & have some questions.
1) I can use the wood (pine/cedar/etc.) & not line it with anything?
2) I'm looking to build about 4 feet long & 7 inches wide. How often/many drain holes would you recommend?
3) Drainage. What can I use for my indoor drainage pans(or water catchers)?
