I'll just say this:
If Washington was growing fiber hemp that he was separating the males from, how come he wasn't working in the fields, and made a special entry about his planting at the "muddy hole by the swamp?"
Then he goes back to the muddy hole and removes the males! Do you think the "muddy hole" was a few hectares? He obviously wasn't breeding anything, as he didn't want seeds, and obviously wanted it way away from his normal hemp.
Also, the first post is a little off here. It mentions that HPS is the same spectrum as the sun, which is untrue. The spectrum of HPS is often said to be like the autumn sun (which it really isn't). Colombia is so close to the equator that it really has NO autumn, and the sun's spectrum there year-round would be much better approximated by a MH lamp.
Another question that would have to answered in the pursuit of the technique of the Gold Weed would be to know where in Colombia it was grown, as the country is quite diverse in terms of landscape, elevation and precipitation and relative humidity throughout the year.
I believe the weed harvest season in Colombia is in January.
