I'm using coco/super soil for the most part and it seems to really hold moisture well so that helps too.
I've actually been over watering even.
Using 3 gal smart pots.
I've been mixing up one gallon a week of additives and then they get plain water when needed. When I give additives they get L-Amino's, carbs, enzymes, terpinator, CalMag+ every once in a while, and sometimes I even add a drop of organic dish soap too as a surfactant.
Those products would be Dark Energy, Hi-Brix molasses, Cannazym, Terpinator, Botanicare CalMag+, and full circle dish soap but I hear dawn is best. Next grow I'm planning to swap the Dark Energy for some Big Bud. Wasn't joking when I said I might try the PBP as well, just wish
@TheYokel would shed some light on which medium to use. On top of that I have been using a three part foliage spray. Optic Foliar Watts, Rev, and Transport. The transport alone is good Vs mold and bugs. I also used a liquid Iron and Zinc suppliment as well as a fish and kelp nute that also has some molasses in it, but only used these two things one time to jump start my plants before the roots really got going into that super soil. I like the whole organic thing, and the idea of less is more, but I've already done that and wanted to try some more stuff. Actually I think all of that is still organic too, except for the foliar spray. It might be organic too I don't know. Terpinator has given better results than I expected. Out of all the products I've used current and in the past, I would give Terpinator the #1 spot, best product I have used. I forgot I also use some Epsom salts every now and then. Compost brew as well. I did use some Microbe Life Plus-C, now that product I might call bs on. It may have helped but it was $16.95 plus shipping and tax, for a 16 Oz bottle, and even I used nearly the whole bottle the first feeding I used it. I over watered like crazy though. For soil it calls for 2-3 Oz per gallon. It's only a 16 Oz bottle. I think I mixed 4 gallons the first time I used it. Thinking I would need to feed each of the six 3 gallon smart pots with super soil about 1/2 gal each. Then mixing up another gallon for the hempy bucket style grow, actually a bato bucket, and also this other batch was to feed a plant in a 3 gal smart pot without super soil, just a coco coir mix. Both the bato bucket and the plant in just a coco coir mix also each got 1/2 gallon. Needless to say I flooded the tent. Didn't realize at the time just how much water coco holds on to, so after a week went by and I went to give their additives they didn't need as much water as I thought they needed because I was more so use to my last grow where I could just water once a week till I saw water pool up in the saucers and then within 10 minutes or so the soil would drink that up and the pooled up liquid would be gone. Not the case when it comes to coco. The coco has been remaining more saturated and wont drink up like soil such as Pro Mix HP has for me in the past. It's been working well giving the additives as only one gallon for all of them to share once a week, they don't need much when using super soil, maybe that super soil and coco is the key to why I can get away with only giving such small amounts of the extras. I'm trying to kind of see how much stuff I can use on one grow this time, see which things might take it to the next level. Run as much as possible without over doing it, and still trying to stay on the organic side. All while not having to ph anything or ever check ppm not even once. And mixing additives is cake, one gallon a week with no headache of checking or adjusting ph. With super soil I could give nothing but water the entire grow and get good results if I want to.
