dada, check out cidly aquabar for a small area grow. Im not sure the dimensions of your cab but they make 24 inch ones that would probably work well. You can build a frame using 2x2 lumber and attach them whatever distance apart you like. Id recommend having them 4 to 6 inches between lights and you can adjust light intensity easily enough by unplugging a few bars. They will do custom spec for no additional charge. I have some plants under these right now and they are doing well. I am using this LED pattern, repeating, 660red, 6500k white, 2700k white. I paid $30 each USD for the 24inch ones plus shipping this spring. I would recommend you use about 30w/sqft for flowering and about 15-20w/sqft for veg. I also got a few lights with a more red in them specifically for flowering, but I havent used them yet. Those are 660red, 660red, 450blue, 620red repeating. I have an apollo2 400 and I wouldnt suggest using it in a small area grow with limited vertical adjustment space, Too much light will stunt your plants and keep them VERY short. If you have any questions just give me a holler and Ill try to help.
