Actually, on one of them I do have glass on the light, because of the way my filter is set up. I get better heat control sucking through the light fixture, although I'm thinking of reconfiguring that one now that we're heading into cooler months. The other is a bare bulb, but I don't notice a significant difference in yield.
I do keep the glass sparkling clean and replace the bulb every other run, which I think helps.
I guess I'm surprised, considering how much you clearly know about growing. I would never have thought I'm pulling heavier weights than you. I guess it's just luck on my part, and good strains maybe.
I never really thought much about it. I guess I just figured most good growers are going to be in that range most of the time. I don't put a lot of stock in yield, because I just know that at the end of every run, however much happens to be there is going to be enough. I like to guess at it every run, and then I get a kick out of seeing how close my guess is.
I keep telling my wife, "One of these days, we're gonna hit 3 pounds. One of these days. I'm telling ya." I feel like some old man waving his cane or something. I want to do it once just for the sake of doing it, but if I never do, it's all good. Production is somewhat important because money is part of the reason we do it, but what matters most is premium quality. We're trying to isolate premium medical strains. I just want to grow the best weed, the kind that when people smoke it they talk about it whenever they're telling stories. I just want to know that people who buy my stuff think they got the best they could get; then I know I did my job.
