Get Your Soil
Potting soil is one of the few recurring purchases you’ll make as a home grower. Soil is extremely valuable to you and your cannabis plants and ought not be underestimated. Ask any farmer who makes wine and grows grapes about the importance of soil quality.
There are many well known “cannabis friendly soils” to choose from, but if you order online, you’ll pay a hefty amount just for shipping. Try to locate your soil from your local garden shop, hydroponics store, grow store, or even hardware store. If you are fortunate enough to get soil like Happy Frog or Ocean Forest from Fox Farms, then you must not add any additional fertilizer for at least 4 weeks. These soils have plenty of nutrients already. However, if the soil is being reused for a second or third cycle, you don’t need to withhold fertilizations.
Cannabis friendly potting soils have all kinds of neat ingredients like peat moss, forest humus, gypsum, perlite, vermiculite, dolomite, coco fiber, worm castings, bat guano, alfalfa meal, crab meal, fishbone meal, kelp meal, oyster shell, humic acid, mycorrhizal fungi and other soil microbes and beneficial soil bacteria. The ingredient list on any soil package always lists ingredients according to which is used most, down to what is used the least. Minerals often found in the soil include calcium, nitrogen, manganese, sulphur, phosphorus and potassium.
Cannabis potting soil options…
Depending on where you live and what is available, here are a few recommended cannabis friendly potting soils. I personally use Fox Farms Ocean Forest and Happy Frog to sprout seeds or plant clones without any problems. If you’re cost-conscious, usually the Happy Frog bags will cost the same as Ocean Forest, but Happy Frog contains more soil. Happy Frog bags often come in 2 cu. ft. bags, whereas Ocean Forest comes in 1.5 cu. ft. bags. Fox Farms also offers a seed starter potting soil. Their Light Warrior is specifically for sprouting seeds. I don’t bother with it. Just another “gardeners choice” matter!4
4 Cannabis Potting Soil Brands: Big Roots, Fox Farms, Roots Organics and ProMix
Fox Farms Light Warrior (for planting seeds)
Fox Farms Ocean Forest 1.5 cu ft
Fox Farms Ocean Forest 12 quart (much smaller than 1.5 cu ft)
Fox Farms Happy Frog 2 cu ft
Fox Farms Happy Frog 12 quart (much smaller than 2 cu ft)
I do not recommend using Miracle Grow time release potting soil, as it releases N (nitrogen) for too long. You don’t want lots of N in the FLOWER phase.
If you can’t find any of the above potting soils locally, you could order them online using the links found here. Or you can ask your local stores for their recommended organic-based potting soil for fruits, flowers, and vegetables. In this case, yes, you’ll definitely want to add perlite to your potting soil. You can always add perlite to any of the above soils too. Perlite helps to keep your soil well aerated. A small 2 quart bag of perlite would be a smart addition to any bag of soil. If you have the space for it, upgrade and save a significant amount of money with a 120 quart bag of perlite.
