Yeah, that and most cash croppers don't let it go long enough. The only thing that holds up well to hot and humid conditions are pure sativas, which nobody grows for money outside of the tropics.
The trouble is, no pure sativa flowers under 100 days with most going over 120, they require 1000 watts plus to even begin to grow flower clusters (much less do well), are VERY low yielding and nutrient sensitive, and you can't keep them under ten feet tall no matter what you do.
But if ever you wanted to smoke a joint at 8 in the the morning and still be high as fuck at 5 PM, pure sativas are the best bet.
