1 Bale sunshine mix #2 or promix (3.8 cu ft)
8 cups Bone Meal - phosphorus source
4 cups Blood Meal - nitrogen source
1 1/3 cups Epsom salts - magnesium source
3-4 cups dolomite lime -calcium source & pH buffering
4 cups kelp meal.
9kg (25 lbs) bag pure worm castings
- Mix thoroughly, moisten, and let sit (uncovered) 1-2 weeks before use.
This is the mix i plan on using for my next grow. My only concern is ph. I use tap water so i know the ph of it is around 7-7.5. I know Non hydroponic soil mixes call for a ph of around 6-6.5
Will I need to buy ph down for this mix?
