Good old recipes from Overgrow 1.0:
Start by pouring a gallon of potting mix onto a potting bench. Add 1 tablespoon each of blood meal for nitrogen, kelp for trace elements, and greensand for potassium; then add 2 tablespoons of bone meal for phosphorus. Mix it all together and you're ready to plant.
Basically Organic mix with ProMix HP as a base. The ratios used for mixing are 50 Litres of Promix combined with with 25-35% wormcastings, 15% Shrimp compost, 750 ml of Bat guano and a cup of Bone & Blone meals. This renders aboot 85-95 Litres of grow mix.
Vic High's Super Soil Mix:
- 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.
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.
- Seabird guano
BOG'S - Feeding and Mix
I use Wal-Mart Continuous Feeding formula potting soil with 5-10% perlite added for aeration and drainage. I add 2 cups of bone and blood meal to every 10 gallons of soil. I feed Pure Blend grow in veg and I transplant 3 times. Starting in 1 qt pots then 2 gallon pots then 4 gallon pots.
I transplant to 4 gallon pots when going to flowering. At this time I give a strong dose of foxfarm bloom liquid bat guano product, 2/3 cup to a gallon. This is a one time heavy nitrogen feed as transplanted and going into high light flowering room. (all HPS 35 watts/sq.ft.)
Often I let them flower until sexed before the final transplant and nitrogen treatment. It doesn't burn them and they shoot in the first 2 weeks of flowering a lot. Capturing this growth "shoot" as I call it is the key to big buds IMHO. Health and vigor is maintained by lots of continued rooting through flower.
I also use some CO2 in flowering and some superthrive once or twice while in flower at a very weak rate. In flower I feed the first half of flowering with Pure Blend Bloom which has half strength nitrogen compared to their vegging formula. Then the second half of flowering I use Earth juice Bloom to feed as it has no nitrogen and my pots still have some.
SubCool taught me to premix my earth juice bloom 20 hours in advance to reduce its acidity and this has helped me feed more without burning them.
