You can still get Mexican commercial but its not worth it. If you have to ask yourself whether you got high or not after smoking it you might as well pop for the good stuff. I don't care what anybody says, the Mexican commercial in the 60's and 70's was a lot better than it is now.
That is not my experience. The last Mexican commercial I got was extremely good and still a bargain compared to the designer weed.
As much money in seeds these days as the bud. Instead of tossing out the males, keep one or two around. Let em hook up with a couple females and encourage the cycle of life. Make your own seeds. Folks are simply cloning anymore. Throw a branch in some rooting hormone and you have a new plant in a week.
It's applicable. Hydro growth is a fast growing business model for farmers, anybody really. You can rent warehouse space a start up a farm. I don't grow weed, but the ptinciple is the same for crop growth. I have a small hydro set up where I run a return pump out of a small fish tank. I use guppies cause they thrive in murky water. I grow lettuce and basil using the same water. Never need to turn the faucet on. Learned you can use natural honey as a rooting hormone. It works fantastic. I rooted 6 pieces of night bloomer in under a week and a half. Just throwing that out there for the plant geeks.
Didn't know about the honey, but it's been 24 years since I ran my hydroponic setup. Technology has come a long way, but farming basics are still farming basics. Many aquarist use plants for nutrient export, same principles are in play with your setup. Fish waste feeds plants, plants remove excess nutrients from water.
