Help, Led lighting for Mini mother bonsai box

Hey guys I'm in the process of designing a grow box for my mother bonsai plants and was wondering if anyone could help me figure out the wattage I would need. The box is going to be 2'x2'x3' and I'm wanting to put 4 mothers in 1 gallon square pots. What led lighting would you recommend for slow steady growth? Other ideas are welcome and appreciated. Thanks in advance.

Sorry even though I searched the forum on the search engine I didn't realize there was a specific place to post this kind of question. Could I get an admin to close this please? Thanks
