FrostyBuds Soil Lab
Grow like the growers you already trust.
Pick a style below — living soil, coco autos, veganic, super soil, guano blends — and get that grower's system: the base mix, the exact recipe with measurements, and the feeding rhythm.
Simple 5-ingredient living soil — the water-only classic
Build the nutrition into the soil up front with dry organic amendments and let microbes feed the plant. Water only (plus top-dress at flower) — no bottles, no pH pens.
The shopping list
- Promix HP (peat base with perlite)
- Earthworm castings
- Gaia Green 4-4-4 (All Purpose)
- Gaia Green 2-8-4 (Power Bloom)
- Mykos (mycorrhizae) at every transplant
Feeding rhythm
Plain water the whole run. One bloom top-dress around day 30 of flower. That's the entire schedule.
Starter pot (1.5 gal)
- ▸1.125 gal Promix HP
- ▸0.375 gal earthworm castings
- ▸4.5 Tbsp Gaia Green 4-4-4
- ▸Coat root ball + hole with Mykos
Final pot (5 gal)
- ▸2.625 gal Promix HP
- ▸0.875 gal worm castings
- ▸5.25 Tbsp Gaia Green 4-4-4
- ▸5.25 Tbsp Gaia Green 2-8-4
- ▸Coat with Mykos at transplant
Bloom top-dress (~day 30 from flip)
- ▸20 Tbsp worm castings
- ▸5 Tbsp Gaia Green 2-8-4
- ▸Scratch into the top inch, water in

- ✦Bloom top-dress (~day 30 of flower): 4 Tbsp castings + 1 Tbsp 2-8-4 per gallon of pot size
Why growers love it
- + Cheapest ongoing cost — no bottled nutrients
- + Very forgiving; hard to overfeed
- + Microbe-driven flavor and aroma
Eyes open
- – Slower to correct if a deficiency appears
- – Mixing day takes effort up front

What actually drives growth
Soil science, decoded.
Aeration is non-negotiable
Roots breathe. 20–30% perlite, pumice, or rice hulls keeps oxygen in the root zone — most 'overwatering' is really under-aeration.
Worm castings are the microbe engine
Beyond gentle NPK, castings inoculate soil with the biology that cycles nutrients. Nearly every great recipe leans on them.
Match N, P, K sources to the stage
Veg wants nitrogen (alfalfa, blood meal, high-N guano). Flower wants phosphorus and potassium (bone/fish bone meal, rock phosphate, kelp, langbeinite).
Calcium & magnesium prevent lockouts
Dolomite lime buffers pH and feeds Ca/Mg; gypsum adds Ca and S without moving pH. Under LEDs, Cal-Mag hunger is the #1 mystery ailment.
Microbes are the flavor secret
Mycorrhizae extend roots; diverse soil biology is linked to richer terpene and aroma profiles. Feed the microbes (humics, teas) and they feed the plant.
Organic vs. synthetic is a real fork
Salts grow fast but demand pH/EC discipline and can mute subtle flavors. Living soil is slower to steer but self-regulating — and most flavor-chasers land there.
