Beginning next winter, I will be using my garage to overwinter a bunch of tropical and sub-tropical fruit trees (eg lychee, mangosteen, citrus, mango) and tropical plants (eg anthuriums, heloconias). The garage is approx 12ft long, 8ft wide and 10 ft high. from april to November, the plants will be outdoors.

Thr first option, will clearly be simpler to set up but a friend has given me a second option that he thinks will provide better lighting (i.e, enable to the plants to flower and fruit more).

If people agree with his assessment, I would be willing to forgo the convenience of option 1 (either way, I will have an electrician install whichever option I go for). Please let me know what you think.

option 1- Super spectrum lighting

approximately 2000w made up of 3 super spectrum lights (1000w, 6000w, and 400w [ I already own a 600w, so I dont have the option of simply buying 2x1000w)
