Good questions! I veg to the 5th node and then right into flower, as I have done for many years. The 600w hps is always 18-24" above the tops. It is still curing (hanging), so I do not have a weight measure yet. Looks like the fimmed girl will end up at close to a lb., but the other girl will be considerably less. I'll post final weight when I get it. I document everything! Peace
