Optimum lumens and time for 5 citrus plants
Hi, I'm pretty new to gardening and growing under lights. I recently got a 6 bulb 4 foot grow light. You can either have 2, 4, or 6 of the lights on at a time. They are ~54 watts each and each output ~5000 lumens.
I currently have 5 citrus trees. Only one of them has any buds on it, and actually has probably about 50. It has one golf ball sized lemon and a new one just started forming today. This one is a meyer lemon tree. I have a persian lime tree and another meyer that are the same size with no buds. These three trees are about a foot to a foot and a half tall. I also have two small trees, another meyer and persian lime. They are maybe half a foot to a foot tall. I also have small Arabica and Musa under these lights. They are probably half a foot each.
I'm trying to get the best results. How long should I leave the lights on daily and how many lights?
