Greetings and salutations all!
I'm an (old) newbie prepping my first grow with some questions (as you'll see!).
First, what are people using as sources of, I believe it is, boric acid or just boron (found in Borax?), as well as zinc? What are the application rates per cubic foot of base mix?
For boron as Borax, I have found agricultural/lawn application rates (1 tbsp. / 100 sq. ft, 1 tbsp. / gallon water applied at 1 fluid ounce / plant) if less than 1 ppm in soil test. (Yes, I should get a soil test done, but it isn't in the budget just yet.) Any thoughts on/experience with application rates /cu.ft base mix? Maybe something like 1/4 tsp.? Would that be safe? Also, there seem to be plants that don't require it. Does our beloved herb even require it? I'm thinking yes on this.
As for zinc, that should be covered by kelp, no? Dr. Duke says so, but it gives zinc for fucus vesiculosus (bladderwrack/kelp) not for our preferred ascophyllum nodosum. Dr. Duke draws a blank on ascophyllum nodosum.
Apologies if I have missed this info somewhere here in ICmag World. I try to do my research before asking, and I hope that my questions can be of help to others!
