I have to Gardenia trees that I have in side under some 6 CFL bulbs that are 1600 lumens and true white. The lamp has some foil to help direct the light and each bulb is about 12 in above the plant.
(Haven't gotten around to buying the florescent tube ones so for now this is what I have.)

The problem is that the gardenias are not full and compact like others I have seen. I have tried fert, repotting, I might make a indoor makeshift greenhouse with a humidifier.

Everything seems to be growing so slow, any help will be appreciated:)
Or if anyone has a cheap solution to grow lights...?
