@jackMgood Hey man, yes, I kicked some serious tail with it, three crops last year. Works awesomely and amazingly well!
I finished my thread in the Organics section called A Garden of Goodies, it describes what I did.
Basically, I mixed it myself with a base soil at strengths between 35 and 75%. I also did a test with their prebagged water only soil cut to 90% strength.
My belief is that 75% works great, and it may be possible to mix your batch at 100% without overdosing autos....with the following caveat:
Mixing directions say to use compost, worm castings, or both. I believe an auto grower needs to favor compost. I.e. don't use all castings since the growth cycle is so short, it will make the Nitrogen too rich. This is what I found with the prebagged at 90%, a bit too much N for one plant, but not too bad. Two plants actually, looked real dark green. So my feeling is that you need to emphasize the compost element over castings.
Apart from that, I would also say DON'T start your seeds in that. I started in one gallon containers for ten-fifteen days, then I bury them in 3s or 5s. You can use an airpot or a fabric pot for starting. If you just bury it, the roots will grow right through the fabric. This way, no transplant shock.
But yeah, I really think their product is awesome. You will save a lot of money compared to bottle nutes, will save time and get nice fragrant, smooth buds. Heavy and dense as well.
For base soil I used Oregon's Only [HASHTAG]#4[/HASHTAG], peat and coco and light amendment. It's a light mix, maybe 300 ppm, nowhere near as strong as Roots or
OF. Has a little worm castings in it already so I tried to account for that when calculating how much compost to add. In the end, eyeballing was applicable. Would recommend to you take notes of what you mix so you can either repeat or modify your recipe. Lol. But yeah, I'm hooked on their product and would never go back to bottles. No calmag probs at all under Led, you'll just want to ph your water a bit with something mild like earth juice down (citric acid). Phosphoric acid ph down is too rough on the microherd. The soil will buffer for you, within reason but not to an infinite degree, so yes, you should adjust to somewhere between 6 and 7, doesn't need to be exact.
I still did a couple "custom" waterings per plant cycle with fulvic, carbs, mycorrhizae, and dilute bone meal liquid or coconut. I'm not entirely convinced this was necessary though.
I did add a bit of biobizz bloom as well in a couple cases where it was needed at 35% strength soil, but when added to 75% was overkill, so I'm confident soil at 75% strength is a good number for most autos. If I were going to use a completely nute-less base soil such as Promix, then I'd shoot for 80 or 85% strength, and just emphasize compost over castings as I've said. Or, run it 100%, I'm just not sure it's really necessary.
Hope that all helps, it's a kickass product :smoking:
