determining sex by forcing and revegging

pros - only need one light space

cons- can lose many weeks waiting for plants to revert
- can cause female plants to crack nanners (although this is usually only a problem in the first few weeks of revegging).

determining sex with clones

pros - donor plants get to continue vegging while clones determine gender
- sex is predictable in approx 3 weeks, sometimes less

cons- need to have two lit areas on different light cycles (although the clone space wont need very much wattage)

I've done it both ways but clone as a rule now... the little bit of extra work can save months if your girls don't readily revert to veg.
