Is Rockwool better to grow with than Soil like Miracle-Grow? Say for instance if I was never to add nutrients to my plant, just let it grow. Which media would be better to grow in. Soil or rockwool.
However, I did buy the Grow/ Micro/ Bloom Combo pack from Advanced Nutrients.com. If I use these nutrients with rockwool with 2 plants inna 4 x 4 foot closet how often should I add nutrients?? everytime I water??
the question is do you want to grow with soil or hydroponics??
if it's you first grow imo, i would start with soil. it eliminates the need for adding nutrients just add water for the whole grow. here's Vic's recipe it's been used a zillion times with great success
best of luck.
Vic's Super Soil Recipe.
Revised Recipe, after several failures due to bad manure sources, I now use the following recipe. Results have been excellent and the clones seem to take off right away instead of having a slow growing settling in period.
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
1 tsp fritted trace elements
4 cups kelp meal.
9kg (25 lbs) bag pure worm castings
- Mix thoroughly, moisten, and let sit 1-2 weeks before use.
Substitutions
- The original recipe was a success, but I simply needed to experiment. In addition, sometimes not all ingredients were always available. Therefore, here are some possible additions and/or substitutions:
Blood & Bone Meal - when trying to cut costs
Kelp Meal - contains over 62 trace minerals. Good supplement for reducing the manure content to speed availability of soil.
Worm castings - excellent source of micro nutrients.
Bat guano - excellent for top dressing a week into flowering.
