Hades Pro Flower Booster - High-Strength Additive for Denser Flowering on Ornamentals
Best for: experienced ornamental growers wanting denser, heavier flower sites without giving up the oils and aromas that make quality flower worth growing.
Our thoughts
This is a strong, specialist additive rather than a general-purpose booster, and it's marked for ornamental plants only, not food crops. If you know what you're doing with PGR-style flowering additives, the 0-26-25 ratio and tight application window (week two or three of flower) give you real control over internode spacing and flower density. If you're new to boosters generally, this isn't the place to start experimenting.
Hades Pro Flower Booster is a high-strength synthetic flowering additive with an NPK ratio of 0-26-25, built to drive flower formation during the bloom phase. It works in a similar way to a plant growth regulator (PGR), shortening internodal distance and triggering the plant to put out more flowering sites, without cutting off the oil and terpene pathways that some harsher boosters can shut down.
It's labelled strictly for ornamental (non-edible) plants only. The manufacturer positions it as distinct from harsher synthetic PGRs specifically because it aims to increase flower weight and density while keeping oil production intact rather than trading one for the other.
How it compares
Hades Pro sits in the same high-strength "PGR-style" flowering booster category as several well-known names, and is often mentioned by growers as a comparable alternative to Green House Feeding's Fruit Machine.
- Green House Feeding Fruit Machine is the closest direct comparison, working on a similar internode-shortening, density-boosting principle.
- Advanced Nutrients Bud Factor X works differently, focused on trichome and essential oil production rather than internode compaction.
- Advanced Nutrients Overdrive is a late-flower finishing additive rather than a mid-flower structural booster, so the two products are typically used at different points in the cycle.
Hades Pro is priced in the same bracket as these established names, and the choice between them tends to come down to grower preference and prior results rather than a clear price advantage either way.
Usage guidance
Dosage
Use 1ml to 5ml per litre of water, applied during week two or three of the flowering phase.
Extra density
For additional density, it can also be used in weeks six and seven of flowering.
Compatibility
It's compatible with other nutrients and additives in your feeding schedule, but should not be used alongside other synthetic flower boosters.
Application method
Apply through the root feed rather than as a foliar spray - foliar application isn't advised once dense flower clusters have developed.
Crop restriction
For ornamental plants only - this is not intended for food crops.

Who this is for
- Experienced ornamental growers wanting denser, heavier flower sites
- Growers comparing PGR-style boosters like Fruit Machine and looking for an alternative
- Anyone growing for flower density and weight rather than leaf or vegetative growth
- Growers who understand strict dosing windows and won't stack it with other synthetic boosters
Not suitable for anyone growing edible crops, or new growers who haven't used a flowering booster before.
Our take
Hades Pro Flower Booster is a specialist tool for a specific job - denser flower sites and shorter internodal spacing during a defined window in flower, without the oil-pathway trade-off some harsher boosters bring. It's not a casual add-on, and it's priced and positioned like the established PGR-style boosters it competes with.
Particularly well suited to experienced growers who know exactly what they're trying to achieve. Worth picking up if you've used products like Fruit Machine before and want to compare results.
