A Marijuana Soil Mix
Ok, there’s been some basic questions lately about growing out some indoor plants using soil. Imparticulary what a good soil mix would be. Asking a person what the best soil mix is happens to be like asking what the best tasting wine is. Every grower has their flavor.
Cannabis grows poorly in soil that is heavily compacted, high in PH, and has poor drainage. With that in mind, you want a moderat PH around 6.7, deep wide holes outside, and lighter fluffier soil indoors/in pots. With that in mind, here’s a soil recipe with proven success. Lets assume were’re going to be growing in a grow bed for this recipe.
Organic potting soil – any brand is fine but i can recommend “Happy Frog” as i have worked with this. If you can find a higher grade soil with coco in it this will be prefered. Your going to need anywhere from 8-10 bags of soil.
Worm Castings. a staple of any soil mix. very easy to produce and a great sustainable solution for food scraps in any household. Worms are your friends. Get as much worm casting as you can. Add anywhere from 5-10lb’s or so…or more!
3/4 cup Azomite for trace elements – not essential to the grow, but will set you apart.
Epson Salt – 1cup should surfice. Add more if deficiency occurrs in flower. i highly doubt it will but if it does, mix a diluted foliar feed.
Bone Meal – 3lbs blood meal
Dolomite Lime – 1 cup
Humic acids are highly recommended. Apply as recommended. usually a couple tablespoons.
Bat guano – 5lbs or so.
a couple 5 gal scoops of perlite.
REmember to let soil dry out prior to watering. Watering is key. A good rule of thumb is try to touch the plants less and keep notes of what you are doing. If you don’t know what you did to mess things up, how will you know how to fix it????
