Well you know just stoner thoughts I've had all summer while I mowed my lawn and now that it's fall it's time for a little testing before spring.
I have a pretty decent looking yard with bermuda turf, but I would love to have a lawn like a putting green for my kids to play on, or even have an area I could turn into a grass tennis court with a little TIO2 and a net (that's the dream).
Lately I've been less into gram per watt and more into gram per hour of my time, which has led me to the use of autopots. I'm digging the concept, though their valve scares me, and all their black plastic isn't great for keeping temps down in a confined space. The concept is similar to the rain gutter gardens which use a netpot hanging out of a 5 gall bucket to wick up the water as needed. As roots suck up moisture the water level drops and a float valve like in your toilet opens allowing water in from a reservoir. Basically both gravity powered, subsurface fed, self watering systems.
I'm thinking about grading an area completely flat with the top 6" being perlite under this layer would be rain gutters with a 1/2" perforated hose (rain bird) running though it that would be connected to a control bucket at one end. Another perforated hose would be at the bottom of the perlite layer and dalylight to drain the perlite when it rains. I'm thinking This would basically give you a hydroponic planting bed to do whatever you wanted including bentgrass.
However, my favorite plant has taught me you have to crawl before you can walk. So step 1 is to see if I can grow bent grass with this method in a controlled environment (basement).
I am setting up a few small scale tests with differing depths of perlite. However, I have no idea what to use for a solution. The only thing I have run across is the Hoagland’s nutrient solution in
this paper http://www.jhbiotech.com/docs/Humic-Acids-on-BentGrass.pdf. I'm an engineer not a chemist. I need nutes that I can buy or produce without a great deal of skill or capital investment.
Anyone got a suggestion? or a wild ass guess for that matter? If not I'm going to try normal Veg solution at 1/4 strength and hope for the best.
