Got a fine mesh home supply filter rig, then a anti-backflow valve, then a pressure reducer (15 psi) then a single station programmable timer, then a hose going over and down to the fertilizer injector rig mounted on a board then going down and out to the 1/2" low pressure lines and the long drip tubes at just under ground level.
I will learn as I go, I suspect, but there is lots & lots of info on the net about this stuff.
All those tomato plants are actually sucker clones from the first 3 plants I bought early last spring --- yes, sucker cloning works and you can even sucker clone determinate varieties as long as you take a fresh sucker from before they grow their terminal set of blossoms.
Hybrids will lose their vigor once cloned 2-3 times in a row, which is why (along with the better taste) "disease improved" heirloom tomatoes are so very popular among us hobby type tomato growers.
You can sucker clone and take seeds from an heirloom variety endlessly (intentionally picking from the strongest best tasting plants that you have grown -- the ones that best fit the environment you live in) and some of the best of the heirloom varieties have disease resistances that have been bred into them over the years.
Flavor is why heirloom varieties are still out there going strong after the 50 years or so of hybrid mania ..... I will be planting some 1910-1930s varieties right along with stuff the pioneers moved across the country that originated in Europe (3 steps from Africa and the Middle East via Italy and France).
Cherokee Purple is one I will grow on the shady side of the back yard in 2020 (origin, NC mountains) along with Black Krim (Crimean Russian origins, supposedly). These do well in partial shade as most tomatoes do not like it too shady.
I will also grow Arkansas Traveler out in the hot full sun, a heat setting friendly very good tasting but smaller sized numerically prolific domestic environmentally tuned take on another old world class classic.
Huge, big tomato for a big sandwich slice, I will do Mortgage Lifter and Beefsteak and I will also do its very round (improved shape) daughter, Delicious, a Chicago World's Fair winner from WW1 era. These are "not for volume production for the freezer" maters as you only get 1-2 really big ones and then a handful of runts off of a vine. I get so tired of finding lots of mid sized tomatoes that when they run to the runt they get sorta useless. My poor soil contributes to this runt problem, I think.

When I throw a runt off of this one, it will still be pretty good sized.
