🌸 Massive flowering
The PK 50-33 ratio directly targets the fruiting phase: more flower sites, denser buds, boosted final yield across your entire indoor grow.
🌊 Marine bio-stimulants
The sea water extract delivers magnesium, calcium, sulfur and rare trace elements. Spirulina adds vitamins A, B, K and antioxidant phycocyanin for vigorous plants.
💧 Perfect solubility
The powder dissolves instantly without residue, ideal for hand watering or hydroponic systems. Economical 0.3 g/L dosage lasts for weeks of use.
When should I use Massive BLOOM in the flowering cycle?
Start Massive BLOOM from the 3rd week of flowering, alongside your base PK nutrient. Keep the 0.3 g/L dosage until the last week before flushing. The bud-fattening phase is when PK 50-33 delivers its best results.
Is Massive BLOOM compatible with other Hydropassion fertilizers?Yes, Massive BLOOM is designed as a PK additive: it complements your nutrient programme without replacing it. It works in synergy with a base flowering fertilizer and pairs perfectly with the Hydropassion range (Prime Sugar, Liquid Ocean) recommended by BloomLED.
Designed in France and hand-picked by BloomLED, indoor growshop expert for 10+ years: Massive BLOOM is the PK additive most used by our customers to go from a "decent" flowering cycle to an "exceptional" one.
