So I have a problem and you know sometimes when your building a super soil it takes time and patience. Ugh! something I don’t dole out very easily. I have got about 150 gallons of super soil in a three by four foot 3ft deep soil “urn” or “bathtub” ? It is going on I year, sage aging, and I want to experiment, which I always do when I have things just right . If I take about half of the soil and mix it with coco coir is this a good combination? I don,’ want to go straight coco coir but do what to see how it responds to a mixing adventure. My soil has life giving amendments to last a plant a full six months with a better way to show me if something is needed. I want to know if 50/50 is good which type coco do you suggest and should I add perlite to get a little more oxygen cushion? Also when you do use coco is a 10 gallon best for flowering size(I use 3 and 5 right now.) Also does the addition of coco allow the planter soil to heat up more and is PH harder to keep. One more thing in coco the PH is best 5.5 to 5.8? and soil 60 t0 6.6 I think so does that also change. Tell me I am crazy and I’ll agree but the show MUSY go on.
When I initially mixed my soil up, I thought that I would add in some Coco that I already had and looking back, I wish I hadn’t mixed CoCo and Peat and just done my Living soil with Peat. I would personally use your soil that is sufficiently cooked. If you are worried about Oxygen content, I would use Pumice or Lava Rock instead of perlite and toss in some Red Wiggler worms. Mixing in the Coco will leach Calcium from your current soil and you will constantly need to add additional Calcium or CalMag.
CoCo is great if you are going to feed liquid nutrients. Take some CoCo and your choice of aeration and go to town. Keep it wet and keep it fed and you will be fine. As for brands, Royal Gold is probably the best. I would stay away from the brick stuff, but if you go that way, make sure to buffer it with CalMag.
thanks for the good information Mr. Zardgreaux
I added a lot of pumis to my made soil. But I wish I had used more. It’s still heavy. I guess I’m glad I did not ad coco though.
