Product description
Aptus P-Boost 500 ml – phosphorus booster for early flower in one or two tents
The switch to 12/12 is when your plants start setting flowers and their phosphorus demand goes up. With 500 ml of P-Boost you cover that early-flower window in one or two tents for several runs.
How far 500 ml goes
Aptus recommends 3–5 ml per 10 L of water from the start of budding until week 6 of flower; experienced growers raise the dose step by step. At that rate, 500 ml treats about 1,000 to 1,650 L of water, or 3–5 ml per 10 L watering can.
What's inside
Aptus P-Boost is a highly concentrated, organo-mineral phosphorus booster with organic phosphorus and organic nitrogen, chelated with L-amino acids for high bioavailability. It supports flower formation and development in the first weeks of flower. Its organic acids lower the pH of your nutrient water, so it doubles as a mild pH down, and it's 100% water-soluble with no residue in your lines.
Small-scale tip
Because P-Boost lowers pH, you may need less pH down than usual, so measure after adding it rather than before. A syringe gives you accurate small doses. If you also use Aptus CaMg-Boost, add one product, dilute and mix before adding the other.
