A-Grade All Stars is a hand-picked range of hydroponic plant boosters and additives trusted by growers for consistent results. The collection spans root stimulants like CYCO Ryzofuel, growth boosters such as HY-GEN Humiboosta, and bloom enhancers including MILLS Ultimate PK and JACKED — covering every stage from propagation through to harvest.
Why these products made the cut
Base nutrients supply the core N-P-K a plant needs, but boosters and additives are what growers use to fine-tune each growth stage — strengthening roots early, supporting steady vegetative growth, and pushing flower size and density in the final weeks. This collection brings together products the A-Grade team has tested and stands behind, rather than every additive on the market.
What's in this collection
JACKED™ — fermented plant juice bloom booster for bigger, stickier flowers and boosted terpenes, from week 3–4 of flower
HY-GEN Humiboosta™ — humic and fulvic acid Cal-Mag booster that improves nutrient uptake at every growth stage
MILLS Ultimate PK — heavyweight PK bloom booster for the final 2–4 weeks of flowering
MILLS Vitalize — silica-based fertiliser that strengthens stems and cell walls, seedling through to harvest
CYCO Ryzofuel — Tasmanian bull kelp root booster for propagation and vegetative growth in coco systems
How to choose
Early stage vs. late stage
CYCO Ryzofuel is built for propagation and vegetative growth, helping cuttings and seedlings establish strong roots, while MILLS Ultimate PK and JACKED are bloom-stage boosters applied in the final weeks of flowering to add weight, density and aroma.
All-stage support
HY-GEN Humiboosta and MILLS Vitalize can be run right through the grow — one improving nutrient uptake via humic and fulvic acids, the other adding structural silica for stronger stems.
If you're just starting out, HY-GEN Humiboosta is an easy, low-risk addition to any base nutrient program. Experienced growers often layer several All Stars together — a root booster early, silica and humic acid throughout, and a dedicated PK or FPJ booster for the final flowering push.
Every product in A-Grade All Stars has been tested in-house — if we don't use it, we don't stock it. Shop trusted brands including MILLS Nutrients, CYCO, HY-GEN and AG Nutrition, with fast Australian dispatch and expert advice from the Cheltenham team.
