Product description
Aptus K-Boost 500 ml – potassium ripening booster for one or two tents
The final weeks of flower are short, so you don't need much product, but you do want the right one. The 500 ml bottle covers the ripening phase in one or two tents for several runs.
What's inside
Aptus K-Boost is an organo-mineral ripening booster with potassium (K) and sulphur trioxide (SO3), plus organic nitrogen and L-amino acids. Potassium supports water management, stomatal function and the build-up of starch and proteins; sulphur plays its part in ripening. The nutrients are organically chelated, fully water-soluble and leave no residue in drippers.
How far 500 ml goes
The dose is 3–5 ml per 10 L of water from week 5 to week 7 of flower; with longer-flowering plants you can use it in the last 4 weeks. At 3–5 ml per 10 L, 500 ml treats roughly 1,000 to 1,650 L of water. For a 10 L watering can you need just 3–5 ml.
Measuring tip
Amounts this small call for a syringe. Shake the bottle, add K-Boost after your base feed, and finish by checking pH and EC. Running Aptus CaMg-Boost as well? It adds weight and firmness and limits the antagonism between potassium and magnesium.
