Product description
Supreme PK Booster 5 L – P, K and iron for denser flowers from mid-bloom
Want more weight in the second half of flower, in a couple of tents or a medium grow? Supreme PK Booster is a flowering stimulator with phosphorus, potassium and iron, plus a carbon molecule that, according to the manufacturer, stimulates photosynthesis. The 5 L can is the entry size of the range.
What each element does
Phosphorus supports cell division and the formation of flowers and fruits. Potassium improves resilience and how efficiently the plant uses water. Iron supports chlorophyll, so leaves keep working while the flowers fill out. Together they help build heavier, tighter flowers.
How far 5 L goes
At just 1 ml per litre, the can makes 5,000 litres of bloom feed. A tent that drinks around 250 litres between week 4 and harvest uses a quarter litre per run, so 5 L lasts many cycles, even split over two or three tents.
Good to know
Because you'll keep this can for a while, store it closed, cool and out of the light, and shake it well every time before use. Add 1 ml per litre with every watering from the 4th week of flower, on top of your base nutrients. Check EC and pH after mixing. In soil it pairs with Supreme Terra Bloom, in coco with Supreme Coco A+B.
