The small shit was just under $150. Problem is, much of that was shipping. I will usually order about anything from Amazon. They are good for ballasts and bulbs too. Ebay is a few bucks cheaper, but you need to know who to use on ebay. Anyway, these vendors on Amazon are bitches. As popular as super soil is, products are always scattered all over. I saw on an episode of the weed nerd subcool went to hydro store and bought all that shit, plus the worm castings (30-50 pounds i believe), 8 bags of soil and a 400 Lumatek ballast for $420. In your area, you should be able to do better than I did. I wanted the best worm casting I can get. I was gonna make compost bin, but I am concerned about consistency. I am not exactly sure where homeless got my castings, possibly the farm itself. Plus I need 8 bags of soil.
It will make almost 2 garbage cans of hot soil. The problem with the cement mixer is the extra time it may take. I will only be able to mix 1/2 or 1/3 batch in mixer at a time. I am going to probably start making 2,3,4 1/2 batches at a time in order to use mixer. Now I am not sure if you know, or I am sure not everyone knows, that the mix is really powerful and you put it in the bottom half(ish, depending on strain) of pot container. The top half will be your regular medium, like a ocean forest. Once the plant is big enough and the roots grow in the super soil and things get good. So anyway, using a full batch of supersoil will last you however long it would take you to go through almost 20 bags of soil. (8 bags, + worm castings, which is bag+, then all other bullshit, which is partial bag, then match all that will reg soil.)
I am pretty damn medicated at the moment so maybe I will edit all this after. lol.
Propane to kill the bugs is real good idea. That is another reason why I have been thinking of using pro-mix vs. soil. I doubt a can find more than a few bundles later on. I am very interested in doing a pro-mix / ff of side-by-side. I don;t have the blood meal and bone meal for 2 full batches though. Fuck it, I do this all the time. Once I get to the small store, my options are almost always fucked. It doesn't help me that they can order the shit. I am on computer more than they are. Anyway, let me quit rambling on and get some shit done.
