HORTI rawK by Green Planet — 0-0-62 Potassium Bloom Bulker for Heavier Flowers

Pairs well with
HORTI rawK is Green Planet's straight-potassium flowering additive — a 0-0-62 formula you run on its own in the final stretch of bloom. Potassium is what drives sugar production, energy storage, and cell strength as flowers fill out. Plants short on it late in flower finish airy and loose; a heavy, targeted dose of potassium instead pushes dense, firm buds and sturdy stems that hold up the extra weight. Used in the last three weeks, with water only, HORTI rawK is built to squeeze maximum weight out of your harvest.

FAQ
When do I use HORTI rawK?
In the last three weeks of flowering. It's a finishing feed that fills out and firms up buds heading into harvest, allowing at least one week of flush before you cut.
Do I mix it with my other nutrients?
No. HORTI rawK runs separately, with water only. It's a standalone late-flower feed, not an additive you drop into your regular nutrient mix.
What does 0-0-62 mean?
It's the NPK ratio — zero nitrogen, zero phosphorus, and a heavy 62% potassium. It delivers a single-element hit of potassium, which is the nutrient that bulks and firms flower at the finish.
How much do I use?
1–2 g per litre of water. In soil, feed once a week; in hydro, add it to a flushed reservoir, circulate 48 hours, then flush and return to fresh nutrient.
Which size should I buy?
At 1–2 g per litre it goes a long way. The 100 g and 500 g suit a single tent or a run or two; 1 kg and 5 kg are the value sizes for regular or larger grows.
