Bloom PHAT — Optimised P-K Flowering Booster

Bloom PHAT — Optimised Phosphorus & Potassium Flowering Booster

PHAT takes a sophisticated approach to flowering nutrition — instead of piling in enormous quantities of dissolved minerals early on, it optimises the plant's use of phosphorus and potassium (the two macros that actually matter during flowering). Promotes flower development through better utilisation rather than just brute-force supply. Fair warning: the effect is noticeable enough you'll want to tell other growers.

Why growers choose Bloom PHAT:

• Optimises PK utilisation — helps plants use the phosphorus and potassium they already have efficiently
• No brute-force mineral loading — smarter approach than just dumping PK into the reservoir
• Promotes genuine flower development — structural flower growth, not just bulking with water retention
• Dramatic visible effect — results obvious enough that growers share with mates
• Works mid-to-late flower — the window where PK optimisation delivers most impact
• Part of a complete Bloom programme — pairs with other Bloom additives for a full flowering stack

Who it's not for:

An additive, not a base nutrient — use alongside a full feeding programme. For pure PK boosting (if optimisation isn't what you're after), Buddha's Tree PK 9-18 is more concentrated. Discontinue 7-10 days before harvest. Follow label dilution; even optimising PK products can cause lockout if over-applied.
