Grenade is a three-bottle range with a clear purpose: controlling plant structure. BLACK is a natural plant growth regulator that tightens internode spacing without the synthetic PGRs that have no place in a crop you intend to consume.
- BLACK: The natural PGR for controlling stretch and tightening internodes - see all flowering boosters.
- GREEN: The companion nutrient for use through the growth stages.
- White MSA: Max Silicon Additive in 250ml and 1L, supplying mono-silicic acid for stronger cell walls - browse all silicon additives.
Why choose Grenade?
Stretch control without synthetic PGRs. Plants that double in height at flip end up with sites too far from the light to finish. A natural regulator keeps the canopy tight and even, and the silicon additive gives the stems the strength to hold what they grow.
