i see how your patients are demanding an organic grow, again use the roots organic, i go through the largest clinic and providers in WA st, and in the back amongst disgarded flood tables, and other stuff that makes me wish they would have a garage(haha) sale! there are stashes of empty RO bags.
when i go for clones, there is ordinarily around 75 - 100 to chose from, if that tells you anything. but i think the use the RO for rooting plants, and mix their own for the bigguns.
while growing this crop in the RO, be working on your own soild mix, its also nice to have the raw materials around. for instance, i have rockwool slabs/blocks, and cubes that i can cut up for clonning, or recent, filling 3 gal pots for flowering in, peat and pearlite 50/50 for a seedling bed, coco and pearlite(65/35) for a nice "organic" soiless mix to keep mothers, or to use in ebb and flow for vegging, then to tranfer into soil for flowering, peat/wormcasts/pearlite(40/30/30) as a top soil or to scatter in arounf the roots while repotting.
use vermiculite/pearlire(50/50) for cuts, or at the bottom of pots like afghans and such whom like prefer, bottom feeding.
be careful with the worcasts, do not use more the 1/20 into your mix. eart juice nutrients have all the things you are looking for;
earth juice - grow is blood meal, steamed bone meal, bat guano, sulfate of potash, sea kelp, and molasses.
EJ catalyst, is oat bran, sea kelp, wheat malt, molasses, and yeast(conditions/fluffs soil, attracts moisture to the roots and builds an environment for microorganisms to thrive in, which is a laaarge part of "organic" growing. you must have those micro organisms, your patients might not understand, that "organic" in this sense should be defined, as
using a living medium.
these nutes are extremely sensitive, i spray my orchids with them, and jamacain bat guano, in a 1/3 solution, and have never burned one flower, and they are notoriously touchy...
i do add a cup or more of organicare - pure granular bloom per 10-12 gallons of soil
it is organic and consists of;
composted poultry litter, fish meal, sulfate of potash, and seaweed. 6% calcium, and 25 humic acid.
i dont see how they can certify some of these things as organic, like the peat moss which cannot be, seaweed, kelp, bat guano, fish emulsion(farm raised id guess ;( ) feather meal, they are harvested from the earth wild so no guarentees can be made, they are hopefully the most pure form of the product, cleansed of harmful impurities and then used. gathered hopefully in a timely, thoughtfull way, unlike hydroton and pearlite which are stip mined, but i can not imagine planting anything in soil w/o pearlite... maybe teracotta pieces, or styraphome... but id rather pearlite.
