You can do it with your set up. 20 inches is not that deep. You could go up
to 6 but cost and electrical concerns might be an issue. You can always try
doing a timed set up on the lighting also making all of the lights come on
for only 4 hours and try out something like that if it seems like too much
light. I'd go with a split of colors say a 5000 and 6700K color.
4 or 6 lights will grow the plants you like. I grow R macradra at 2
watts/gallon and some other folks do it at 2.2 to 2.5 not problems but CO2
and nutirents are in good supply.
