Grenade Black

Grenade Black is an advanced hybrid organo-mineral flowering additive, naturally formulated to maximise healthy & heavy yielding harvests. It’s a new vision “Super PK” combining the benefits of high quality minerals with amino acids, phytohormones & other biological co-factors.

Grenade Black increases plant energy levels (ATP) & optimised sulphur content enhances secondary metabolite production. Grenade Black combines a bulk building & ripening product in one, applied at a concentrated dose rate saving you time & money!

Dose Rate: 0.2ml – 0.4ml per litre. (weeks 5, 6 & 7 of the flowering cycle).
