Simple. Look up the Clackamas Coot soil mix. Or look up my post from early 2019 that’s when I mixed my batch and haven’t looked back since. If you go on YouTube and type in Clackamas Coot a lot of videos and zoom meetings will pop up with his name and if you listen to it you will never go back to growing with bottled nutrients. Anything on those bottles is 98 percent water and the rest you can buy it yourself and make it at like 100 times cheaper and 100 times more concentrated. The first podcast I recommend is the 3 part series with Tad Hussey from KIS organics. Type in KISORGANICS on YouTube and it will pop up. I tried getting this mix added to the GWE tutorials but I got ignored. Reason why I want to include it is because the old Subcool RIP recipe is a lot of work to make a lot more amendments and some of the amendments used are not good as in quality or sustainability. You will have to unlearn all the unnecessary things you learned here like using PH pen ph up ph down, runoff, no cal mag, no this no that lol. I just can’t believe Nebula or Sirius won’t atleast try this mix and hopefully add it to GWE being that it’s very simple, low cost and the quality of your buds is great, but they promote kindsoil which I don’t think they are too happy with also a lot of people complain about it plus it’s really expensive. Living soil to me is a soil mix with no slow releasing fertilizers, amended with quality organics inputs and you just rely in the microbiology to do as in nature. When done with a full cycle you just reamend or not and just cut the plant at the stalk without disturbing the soil no need to throw it away because by then you have a web of mycorrhizae and microbiology alive in the soil that only gets better and better after each use. The bugs in the soil find their way there on their own a sign of healthy soil. That’s why you don’t want to use slat based chemicals made in China most likely because they will kill the soil life. If you have any more questions because I’m confusing you just ask. I would really like for more of us growers to use living soils all those other bottled nutrients are just a scam I mean if one is so great why is there so many and none can make a nutrient bottle so good that they are making billions on it feeding the world specially when they are 98 percent water and super expensive. Seriously look at your bottles look up the ingridents and you will see for yourself. A favorite here general hydroponics I’ve heard some shitty things which I will look into so I can post here. Let me know what you think...
