hydro

sure.. the vermiculite even adds a little available silicon, too. check out some wickedtstyx gows with the all perlite and recirculating drip irrigation system... can't grow much more effciciently than that. growdiaries.com/grower/wicked-stix -- @wicked_stix... hydro is the simples thing to do as far as the nutes... 650-750ppm mix every irrigation and you are golden. (or ebb/flow, drip whateer). i have a ppm beakdown for my soilless grow. it'll be same as for "hydro". sceenshot in any diary, just about.. my full power mix is 720ppm.. what is shown is merely a ballpark that shifts as needed based on observanaces from plant and stage of life.. generally just requires adjusing N down a bit in bloom by 5-10% . if i give any more p or k it burns the plant at any stage.

What are you gonna be doing exactly like a DTW top drip feed with those? You can begin to dabble with it with coco pretty easily and manually water.
