01 / Solubility
3 lb per gallon stock tanks.
V1, V2, B1, and B2 each dissolve up to 3 lb per gallon at room temperature. Full Tilt™ goes to 2 lb/gal; Bulky B™ to 1.5 lb/gal. Headroom for injectors and large reservoirs.
FloraFlex® Nutrients · Commercial-grade powder program
A complete dry-nutrient program engineered for every stage of the grow.
Six SKUs. One straightforward feed schedule. V1 and V2 carry vegetative growth. B1 and B2 carry bloom. Bulky B™ stacks early-to-mid flower. Full Tilt™ finishes the cycle. Every product is water-soluble, fertigation-ready, and built for commercial scale.

What it is
What are FloraFlex Nutrients?
FloraFlex® Nutrients is a six-SKU, water-soluble powder fertilizer program built for commercial cultivation: V1 and V2 cover the vegetative stage, B1 and B2 cover bloom, Bulky B™ is an early-to-mid flower stimulator, and Full Tilt™ is the late-bloom ripener for the final weeks before flush.

The Program
One program. The whole cycle.
Every FloraFlex Nutrient SKU plays a defined role in a defined window. Here is how the eight-week cycle reads end-to-end, based on the published Full Tilt schedule.

Week ranges and per-gallon doses are summarized from the published FloraFlex Full Tilt feeding schedule. Always follow plant response and adjust to your target EC.
Why dry, why two-part
Built for the stock tank.
FloraFlex Nutrients is intentionally narrow: two parts in veg, two parts in bloom, and two stage-specific boosters. Every SKU ships as a dry powder, dissolves at concentrated rates, and slots cleanly into a Doser or fertigation skid.
02 / SKU stack
Two parts, two stages.
Instead of a 4–8 bottle program, the base runs on two parts in veg and two parts in bloom. Fewer pallet positions for resellers, simpler training for new room staff.
03 / Freight
Dry shipping economics.
Powder concentrates ship pounds of fertilizer in the space and weight of bottled equivalents. Stores at room temperature. Doesn't freeze in cold trucks the way bottled liquids can.
04 / Flexibility
Three regimens, one stack.
Run the standard Full Tilt schedule with preferred Cal/Mag, the No Cal/Mag Full Tilt schedule, or the Super Simple B1/B2-only schedule — the same SKU set flexes to your water source.

Feeding schedules
One stack. Three regimens.
Match the program to your water and your operation. Each schedule uses the same SKUs in a different sequence — switch between them below.
Full Tilt — with preferred Cal/Mag
The standard FloraFlex schedule. Start each feed with a low EC contribution of your preferred Cal/Mag, then mix V1+V2 in veg or B1+B2 in bloom. Bulky B is omitted in this schedule in favor of Full Tilt taking over for the late ripen window.
| Week | Cal/Mag start EC | V1 / B1 (g/gal) | V2 / B2 (g/gal) | Full Tilt (g/gal) | Target EC |
|---|---|---|---|---|---|
| Veg · Wk 1 | 0.3 | 2 | 2 | 0 | 1.6 |
| Veg · Wk 2 | 0.3 | 2 | 2 | 0 | 1.6 |

| Bloom · Wk 7 | 0 | 0 | 0 | 8 | 1.6 |
| Bloom · Wk 8 | 0 | Flush — clean pH-adjusted water only | — | ||
All gram values are per gallon. Start EC values are with your preferred Cal/Mag. Adjust ratios if you are not reaching the target EC. Always follow plant response and reduce by 0.3 g/gal per input for 2–3 days if you see tip burn. Optimal rates depend on plant variety, growing system, and environment.
No Cal/Mag Full Tilt
For growers whose raw water and base parts already supply enough calcium and magnesium. Higher base concentrations and a slightly different bloom sequence — Bulky B layers onto B1+B2 from week 2 of flower through week 5 before Full Tilt takes over for the ripen window.
| Week | Veg foliar (g/gal) | V1 / B1 (g/gal) | V2 / B2 (g/gal) | Bulky B (g/gal) | Full Tilt (g/gal) | Target EC |

All gram values are per gallon. Confirm your raw water and base parts supply adequate Ca/Mg before running this schedule. Bloom foliar values follow the published No Cal/Mag chart. Extend Week 4 of veg for longer veg times.
Super Simple — B1 + B2 only
The lowest-complexity way to run the FloraFlex program. B1 and B2 only, mixed at 5 g per gallon each across every week of veg and bloom, with a clean-water flush on week 8. No additional Cal/Mag is called for in veg or bloom on this schedule.
| Week | B1 (g/gal) | B2 (g/gal) | Target EC |
|---|---|---|---|
| Veg · Wk 1 | 5 | 5 | 3.0 |
| Veg · Wk 2 | 5 | 5 | 3.0 |

No additional Cal/Mag is needed in veg or bloom stages on this schedule. Use the FloraFlex Nutrient Calculator to convert per-gallon dosing into stock-tank concentrations for fertigation.
FloraFlex System
Built for the Doser.
FloraFlex Nutrients is one half of a system. Powder format, high-solubility batching, and the published feeding schedules are designed to run cleanly through FloraFlex Dosers and standard fertigation skids.
01
Stock-tank ready
V1, V2, B1, and B2 dissolve up to 3 lb per gallon at room temperature. Headroom for large reservoirs and injector pods.
02
Calculator-supported
The FloraFlex Nutrient Calculator converts per-gallon mixing instructions into stock-tank concentrations and dilution ratios.
03
Doser regimens
FloraFlex publishes Doser and fertigation feeding regimens that align with each of the three published nutrient schedules.
04
Foliar friendly
The veg and bloom foliar inputs in the No Cal/Mag schedule give you a foliar layer that uses the same SKUs you already inventory.
Wholesale & reseller
Stock the whole program. Six SKUs cover the cycle.
FloraFlex Nutrients ships in 1 lb, 5 lb, and pallet quantities. Resellers stock a complete commercial feed program from six SKUs instead of a fragmented multi-bottle lineup — simpler ordering, lower freight, and the same regimen that the FloraFlex Calculator already supports.

FAQ
Buyer questions, answered.
The questions commercial cultivators and resellers ask before they place an order.
FloraFlex Nutrients is a six-SKU water-soluble powder fertilizer program covering the full grow cycle: V1 and V2 in veg, B1 and B2 in bloom, Bulky B as an early-to-mid bloom booster, and Full Tilt as a late-bloom ripener. Every product is water-soluble and built for stock-tank or per-gallon mixing.
At minimum: V1, V2, B1, and B2 — the two-part veg base and the two-part bloom base. That set alone runs the Super Simple schedule. Add Bulky B for a PK booster across early-to-mid flower and Full Tilt for a dedicated finisher in the last 1–2 weeks before flush.
V1 and V2 are the vegetative base; B1 and B2 are the bloom base. Within each stage, Part 1 carries the nitrogen-led chemistry and Part 2 carries more phosphorus and potassium. They are designed to be mixed together 1:1 by weight per FloraFlex schedules, not used as standalone single-bag feeds.
Bulky B is a PK-style stimulator that stacks onto the B1/B2 base during early-to-mid flower; FloraFlex describes it as engineered to support flowering site development. Full Tilt is a higher-P, higher-K ripener used in the last 1–2 weeks before flush. They are sequenced across bloom, not used at the same time on every schedule.
It depends on your water. FloraFlex publishes both a standard Full Tilt schedule that assumes preferred Cal/Mag added at low EC and a No Cal/Mag Full Tilt schedule for growers whose raw water and base parts already supply enough calcium and magnesium. The right path depends on your source water.
The Super Simple schedule runs B1 and B2 only at 5 grams per gallon each across both veg and bloom, with a week 8 flush. It is the lowest-complexity way to run the FloraFlex base. No additional Cal/Mag is needed in veg or bloom on this schedule.
Yes. The line is formulated as water-soluble powders intended for hydroponic and inert-substrate cultivation, including coco coir, rockwool, and recirculating systems. Match your EC target to the published schedule rather than assuming the same gram-per-gallon dose across every substrate.
At room temperature: V1, V2, B1, and B2 each dissolve up to 3 lb per gallon; Full Tilt up to 2 lb per gallon; Bulky B up to 1.5 lb per gallon. Always confirm full dissolution and check EC before feeding plants.
Targets vary by stage and by which of the three schedules you are running. The No Cal/Mag Full Tilt schedule runs roughly 2.4–3.0 EC in veg and finishes at ~1.6 EC in the final ripener week before a week 8 flush. Always follow plant response and adjust ratios if you are not hitting the EC value shown on the chart.
Yes — the line is built for it. Concentrated solubility, dry powder format, and the published Doser/fertigation schedules are why the program is positioned for commercial cultivation. Pair the lineup with the FloraFlex Nutrient Calculator to convert per-gallon dosing into stock-tank concentrations.
Same two-part logic, different format. Powder concentrates ship lighter, store at room temperature, and dissolve at much higher per-gallon strengths than ready-to-pour liquids, so per-feed cost and freight cost both drop at commercial volume. The trade-off is that you batch your own stock solutions instead of pouring a pre-mixed liquid.
