Veg & Bloom Booster Bundle — living fermented supplements for the full crop cycle

Bundle — Save vs Buying Separately Fermented with EM-1 Veg + Bloom Pair Living Microorganisms Handcrafted in Stockport Recycled Plastic Bottles

Two handcrafted fermented fertilisers — one for vegetative growth, one for flowering and fruiting — designed to work as a pair across the entire crop cycle. Both are fermented with the same EM-1 beneficial microbe culture, maintaining biological continuity in the root zone from transplanting to harvest. Both contain in-house grown aloe vera and humic acid. The difference is what feeds the plant at each stage.

How the system works

Veg Booster — transplant to first flower buds

  • Nitrogen-rich for leaf expansion, stem development, and root establishment
  • Mealworm frass — nitrogen + chitin for immune defence priming
  • Worm castings — beneficial microbes and humic substances
  • Scottish seaweed — natural cytokinins and auxins for cell division
  • Aloe vera, humic acid, EM-1 culture

Bloom Booster — first flower buds to harvest

  • Zero nitrogen — phosphorus and potassium for flowering and fruiting without pushing leaf growth
  • Micronised rock phosphate — fermented for 3+ months into plant-available P
  • Sulphate of potash + potassium mineral — dual K for fruit quality and sugar transport
  • Organic banana peel — potassium and organic acids
  • Aloe vera, humic acid, EM-1 culture
  • Zero nitrogen means you can apply right through to harvest

The transition point is simple: use Veg Booster weekly until you see flower buds forming, then switch to Bloom Booster weekly for the rest of the season. Both products use the same dilution rates, the same application methods, and the same EM-1 culture — the only thing that changes is the bottle.

These are supplements, not base feeds

Both the Veg and Bloom Boosters are designed to be used alongside a base Dr Forest fertiliser — not as replacements. Use them as weekly additions to your existing feeding programme to add beneficial microbes, biostimulants, and stage-specific nutrition on top of your base NPK.

Handcrafted in Stockport

Both products are fermented by hand in small batches at our workshop in Stockport, Greater Manchester. The aloe vera is grown organically in-house at Dr Forest HQ. Each batch takes a minimum of 14 weeks to produce. Supplied in recycled plastic bottles.

What's inside: ingredients & fermentation process

Shared foundation

Both products share the same biological foundation: Dr Higa's EM-1 (Effective Microorganisms — phototrophic bacteria, lactic acid bacteria, yeasts, actinomycetes, beneficial fungi), aloe vera (grown in-house, contains salicylic acid and saponins), humic acid (chelator and microbial food), molasses (microbial energy source), and Supa Cera C powder (EM ceramic). Both undergo the same two-stage fermentation: 3+ months anaerobic mineral/organic extraction, then 2 weeks EM-1 activation at 25°C+.


01

Veg Booster — Unique Ingredients

Mealworm frass: nitrogen, phosphorus, potassium, and chitin. The chitin triggers chitinase enzyme production in plants, priming immune defences against fungal pathogens and root-feeding insects. Worm castings: rich in humic substances, beneficial microorganisms, and plant growth hormones — fermented to extract these compounds into solution. Scottish seaweed: natural cytokinins, auxins, alginates, and mannitol — plant growth hormones that promote cell division, root initiation, and stress tolerance. British-sourced from the Scottish coastline.

02

Bloom Booster — Unique Ingredients

Micronised rock phosphate: natural phosphorus source dissolved through 3+ months of anaerobic fermentation into plant-available forms — the energy currency that flowering demands. Sulphate of potash: chloride-free, fast-acting potassium for sugar transport and fruit quality. Potassium mineral: slow-release potassium for sustained background supply. Organic banana peel: potassium-rich organic matter fermented with the EM-1 culture, also contributing phosphorus and organic acids. The Bloom Booster contains zero nitrogen — deliberately, so it can be used right through late bloom to harvest.

03

Why the Pair Works Better Than Either Alone

Plants have fundamentally different nutritional needs during vegetative growth and reproductive development. During the veg phase, nitrogen drives leaf expansion and stem development — the solar panels and plumbing the plant needs before it can produce fruit. During flowering, excess nitrogen diverts energy away from reproduction and delays ripening. By switching from a nitrogen-rich Veg Booster to a zero-nitrogen Bloom Booster at the right moment, you match the supplement to the plant's actual demand at each stage. The shared EM-1 culture maintains biological continuity — the same beneficial organisms colonise and persist in the root zone throughout the entire crop cycle.

04

Living Fermentation vs Sterile Fertiliser

Both products arrive containing active, living microorganisms. Conventional liquid fertilisers are sterile chemical solutions — they feed the plant but do nothing for the soil biology. These fermented supplements inoculate the root zone with beneficial bacteria, yeasts, and fungi while simultaneously delivering mineral nutrition and biostimulant compounds. Each weekly application reinforces the microbial workforce in the soil, building disease suppression, nutrient cycling, and organic matter breakdown capacity over the season.

How to use: the full-season fermented programme

Both products — same rates, same methods

Veg Booster and Bloom Booster use identical dilution rates and application methods. The only thing that changes when you switch is the bottle.

Application rates — both products

Foliar spray

Rate: 5–10 ml per litre of water  |  Frequency: Weekly

Strain through a fine sieve or muslin before adding to a sprayer. Apply as a fine mist to both leaf surfaces in early morning or late evening.

Root drench

Rate: 5–20 ml per litre of water  |  Frequency: Weekly

Dilute and pour directly around the root zone. This is the preferred method for delivering the beneficial microorganisms to the soil. No straining required for watering can application.

The seasonal programme

Phase 1 — Vegetative growth (Veg Booster)

Start: After transplanting or once seedlings are established  |  End: When flower buds first appear

Apply Veg Booster weekly alongside your base fertiliser (Veg 4-4-4, All-Purpose 6-6-6, or crop-specific). The nitrogen, chitin, and seaweed hormones support rapid leaf and root development. The EM-1 culture begins colonising the root zone from the first application.

Phase 2 — Flowering and fruiting (Bloom Booster)

Start: When flower buds first appear  |  End: Harvest

Switch to Bloom Booster weekly alongside your base fertiliser. The zero-nitrogen formula delivers phosphorus and potassium for flowering and fruit development without pushing unwanted leaf growth. Because it contains no nitrogen, you can continue applying right through to harvest — no need to stop early. The same EM-1 culture is maintained in the root zone, ensuring biological continuity.

This is a fermented product — both bottles smell strong

The sour, yeasty odour is completely normal and indicates active microbial cultures. It dissipates rapidly after dilution. Shake both bottles vigorously before each use.

The complete programme

Base feed: Dr Forest granular fertiliser (Veg 4-4-4, Tomato 3-4-6, Rose 5-3-5, etc.) applied as directed. Weekly supplement: Veg Booster during vegetative growth → Bloom Booster from flowering onwards. Fortnightly biostimulant: Add Seaweed Powder for additional growth hormones and alginates. Fruiting calcium: Add Cal-Mino chelated calcium from fruit set onwards. This four-layer system covers mineral nutrition, living biology, biostimulants, and calcium delivery across the entire crop cycle.

Frequently asked questions

One bottle of Veg Booster and one bottle of Bloom Booster — both fermented with EM-1 beneficial microorganisms. Choose your size: 250ml+250ml, 500ml+500ml, or 1000ml+1000ml.
When you see the first flower buds forming. This is the transition point — the plant is shifting from vegetative growth to reproductive development. Switch bottles and continue the same weekly application schedule.
Both are available individually. But they are designed as a pair — different ingredients matched to different growth stages. Using both gives your plants the right nutrition at the right time, with biological continuity from the same EM-1 culture throughout. The bundle saves versus buying separately.
No. Both products are supplements — they add microbes, biostimulants, and stage-specific nutrition on top of a base feed. Use alongside a Dr Forest base fertiliser (Veg 4-4-4, All-Purpose 6-6-6, Tomato 3-4-6, etc.) for complete mineral nutrition.
Nitrogen pushes vegetative growth — leaf and stem development. During flowering and fruiting, excess nitrogen diverts energy away from reproduction, delays ripening, and dilutes fruit sugars. The zero-nitrogen Bloom Booster delivers phosphorus and potassium without any of these side effects, and can be used right through to harvest without needing to stop early.
Both are fermented products containing active microbial cultures. The sour, yeasty smell is normal and indicates a healthy fermentation. The odour dissipates rapidly after dilution and application.
For root drench with a watering can — no. For foliar spraying — yes, strain through a fine sieve or muslin to prevent sprayer nozzle blockages. Both products are pre-strained through 200 micron during bottling.
Cool place, out of direct sunlight. Do not freeze or exceed 35°C. The bottles may produce gas from ongoing microbial activity — open carefully. Use within 6 months for best results. Shake vigorously before each use.
Yes. Both products are supplied in recycled plastic bottles.
