The grapefruit is grown under 4 foot fluoro in veg 64 watts total. In flower I have 300 watts HID and 200 watts cfl. A very simple set up. The plant that cola came off of will probably be 1/4 lb, and I run 4-6 plants perpetually in flower.
Outdoor grapefruit female and her intended sexual partner, a male Captain Jack from a local breeder, homebrew420. Both started to flower about a week ago.
Outdoor grapefruit, flowering for about two weeks. Male Captain Jack for pollen. First male I ever flowered out in 15 years. Fun because its different and I can't wait to make a cross.
