My new EC/PPM meter gets here today, and so do my fabric pots. I got a set of 3 gallon pots to stick in the hydro room. Gonna start with my garden soil I've been cooking for a 5 years. It's been in clover for 8 months now and has been amended with everything imaginable over the last few years. Perlite, vermiculite, several pounds of quartz and other crystal and rock dusts, kelp meal, blood and bone meal, epsom salts, mollasses, cover crops, myco inoculations, teas, several types of compost, no-till for three years. before the no-till I worked the base soil with sand, gypsum, chicken poo, and lime. Should be fun to see how it does indoors. I might end up with bugs at first.
