tedcun Reviewed by tedcun on . First grow - GRAPEFRUIT 250 HPS in a cupboard. 3 fem. grapefruit and 1 hindu kush ( prob. male ;) ) I've been trying to scoure the net for any info. about gf.

For Veg: Starting 24hrs for a week then reducing to /18/16 each subsequent week followed by a 36hour dark period prior to flowering Flowering: 12/12 for ~2months I'm planning on transplanting from Rating: 5
