Well my plants are all 3 weeks into Veg & about 14" - 20" tall. I want to find out if they are male or female so I took some clippings that had at least 3 nodes on them & stuck each one in it's own plastic cup in about 1" of water pH 6.5. Then I put them about 6" away from my T-5 & CFL's on a 12 / 12 cycle. Did I do it right ? If I did...about how long till they will show sex signs ? This is my 1st go at this so any tips on it are very welcome. Thanx !!!
