I will be discussing a method I use which I have found to be clean, organic, productive, high quality, and a very cost effective solution for growing cannabis. Super soil takes out the guess work and allows the plant to choose what nutrients it wants to take up. It is not really necessary to follow the recipe to a T.
You most likely won’t be able to source every ingredient and in most cases you will have to compensate some ingredients for others. The basic measurement to look for is a NPK ratio. Nitrogen, Phosphorus and Potassium are the main chemicals. I look in the ranges of 12 on N, up to 18 on the phosphorus( high phosphorus for flowing) and 10 on the K.
Tools you will need: Shovel with kiddi pool, or concrete mixer or tarp
A basic recipe down below can be mixed and matched with other recipes ingredients as long as you have a the NPK ratios as suggested above. They don’t need to be exact.
Start with your base soil for example I use a kiddi pool and full it mixes about 3, 20 gallon pots. I use larger pots because the roots like space to grow after being transplanted as a teen cannabis plant( about 4 nodes tall). The bigger pot will allow your plants space to grow throughout the season without chances of nutrient deficiencies.
In the kiddi pool put your base soil pro mix in first. I use about half the cube of promix. Then a big 25 or 30 lb bad of worm castings. Add about 1/3 of the bag. Next refer below to the amount of cups per pool mix. Mix all the other ingredient and mix with shovel. it will look like a big mountain. to add ingredients make a volcano in the top and add the other amendments. Like Bob Marley said “stir it up”. I like to put the top of the mix on the bottom of the three pots divided and then top. That way the hotter nutrients are at the bottom and less likely to burn plants. Make sure tour plant is about 4 nodes high before transplanting to the bigger pots of super soil. Smaller plants can’t take the nutrients. Starting seeds: I use the paper towel method: Put seeds in small wet section of paper towel do not let them dry out! Keep them moist but not drowned and In a dark place. When you see the taproot, put it root down into a hole, in a solo cup, or small pot a similar size and bury the head of the seed just below the soil and cover. Use only Pro mix plain when the seed goes into the dirt and no super soil. It won’t be until the plant has almost root bound it’s cup and have about 4 nodes before you transplant into super soil. Note: Purchase a water filter, I use tall boy filters and change the filters out each year. After you mix the soil filtered water only! If you see a deficiency with a plant you can top soil with the recipe you used or something close to it. Also for mold prevention use crushed egg shells. personally I compost all my food and it’s in my soil. I recycle the soil from the pots after the end of the season and the next year I re amend it with the recipes or something close.
