What is it?

Grenade Black is a natural hardener, developed from scratch as an alternative to chemical based PGR’s. Grenade Black won’t mutate your crop, it will accentuate it naturally.

When do I use it?

Used primarily in weeks 5,6 & 7 of the flowering phase (can be used from week 3 at 0.2ml/L and always double dosed in weeks 6/7 at 0.4ml/L). It has an NPK of 3-9-19.

Tell me more!

Grenade Black is not "just a PK", it is much more than that. You would have to combine several other products on your shelves to achieve what Grenade Black contains.

Unlike a synthetic-based hardener (chemical PGR) Grenade Black won’t regulate smells, flavour or taste. It will however increase what is naturally available within the plants genetic potential and make it the best version of itself.  

Grenade Black has a small EC value if 0.2. So if you follow a feed chart, it's recommend you add it in first, before your base nutrients and other additives.

You can use it with any other nutrient brands, and alongside their boost products, e.g Canna boost, Dutch Pro Explode etc. We only recommend that if you want to run your PK alongside Grenade Black that you simply keep an eye on your plants. If you see any leaf curl or tip burn then simply pull back on your current PK and let Grenade Black do it’s thing. You will only see this if the genetics of the plant won’t take both. Most genetics will, but to be safe keep an eye on your plants. Don’t panic, Grenade has a stress reliever built into it and you will see your plants right themselves.
