i am germing 50 or so seeds i have and i want to put them right to 12/12 to force sex then back to veg ,is this possable?
It is, but you could cause a rampant hermaphrodite spawn. With 50 seedlings I'd start them all off at 18/6 for a few weeks, pick the best two or three and keep em as mothers, then just 12/12 everything else. You'll get a good pull from it.
