I was using Espoma last year. I found it to be a little harsh. I really think that all of the N was soluble and didnt have much of slow release N. What I mean is that the leaves would fade and curl around week #5 and it would go down-hill fairly fast from there. I was using it because it was very close to TGA's super-soil. Yes, I started off being a weed nerd.
I did a side by side with Build-a-Soil's craft blend, and the craft blend kept the leaves green until it was supposed to. I am not telling you to buy from this company, but the ingredients used are very close to what Grease told me to use. I finally feel like I can recycle my soil like I am supposed to like plant clones in it! I was buying this cheap bag soil because my recycled super-soil was burning everything. Probably PH issues or something, but I put that shit in my garden!
Here is Build-a-soil. It would be cheaper to source the amendments individually, but this is very convenient.
- Brew All Around Balanced Nutrient Tea's for Veg - Flower (1/2 - 1 Cup Per 5 gallon Bucket of Water)

Adding up all of the Approximate NPK values published for these products from the manufacturer and then dividing by the amount of parts we end up with a very nice NPK guesstimate of 3-4-2. Once we get the blend tested we will publish actual results.
