OK, Here's the story; I am making my own soilless potting mix for an indoor (4x4 Mylar tent with 16 plants in 3 gal black nursery pots will be under a 1000 watt HPS) SCROG grow. The screen will be 12" above the medium.
I have been an avid organic gardener all of my life and have been growing pot for 40 years, but only outside in the ground. This is my first indoor grow in containers. So I need some coaching from you guys with more experience in this area. Using what I already have around the shed, this is the mix I am planning (mothers and seedlings are vegging under CFL's and are about ready to clone so I still have a little time to tweak this mix before I actually combine the ingredients). I don't want to screw it up because I am making a large batch and bagging it for future use. Here it is;
8 cubic ft of compost (black humic compost, I bought a trailer load from a landscape supplier)
2 cubic ft of Canadian Peat Moss
40 pounds (3 or 4 cubic ft?) of worm castings (I have a total of 80 lbs)
1 cubic ft of well composted chicken manure (I have 3 cu ft total)
16 quarts of Perlite
5 lbs of pelletized Garden Lime
4 cups bone meal (I have 5 lbs)
4 cups blood meal (I have 5 lbs)
1 lb Rock Dust minerals
I would really hate to go thru all that work and have it fry or overwhelm my plants. I would like to adjust the proportions so that I don't have to buy to much more stuff.
Well, there it is. Any comments or suggestions would be greatly appreciated. Thanks in advance!
