  1. A friend of mine wanted to grow, but it would have to be a stealth grow. I have several questions...

    What is the earliest/reliable way to tell which plants are males and which are females and, how many CFLs should he use to veg 10 seedlings to this time?

    Please nobody tell me about how much he should switch to HPS, he doesn't have that kind of money... so back my question is, what is the earliest/reliable way to tell the sex of the plants? and how many CFLs?
  2. plants can show sex in 4-5 weeks, depending on strain and soil conditions. you can put them into flower at 12inches or 5 weeks, i suppose whatever comes first. the more cfls you can put in, the better. have no idea what type of space youre using, so couldnt answer your cfl question.
  3. another way to tell sex if u dont want to spend 4 or 5 weeks waiting is to take a small clone and seperate it from the other plants and put it under 12/12 lighting. after that it should show flowers and u don't have to wait to flower the whole plant.
