Key to Life Key to Kelp Pairs Seaweed With Real Potassium
Most kelp powders are gentle trace-element inputs, and this one is built differently on purpose. The guaranteed analysis is 1% nitrogen and 13% soluble potash, with the potassium coming from kelp and potassium hydroxide. The kelp itself is Ascophyllum nodosum, the North Atlantic brown seaweed used across most quality extracts. It ships as a dry, water-soluble powder, so nothing you pay for is water. For root drenches, hydro and aero reservoirs, and foliar sprays, the rate is 1/2 to 1 tsp per gallon. As a top-dress, Key to Life calls for 1 tsp per gallon of soil, scratched in and watered through. Compost teas take a lighter hand, at 1/4 to 1 tsp per gallon. Start at the bottom of the range in early veg and climb as the plants size up. Because the potassium arrives partly as a hydroxide, the mix runs alkaline. Check pH after it dissolves and bring it back down before feeding. Foliar passes go on early in the light cycle, and the flowers should stay dry once they have set.
A High-Potassium Kelp Fertilizer for Heat, Drought and Heavy Bloom
Key to Life positions this as the jar to reach for when a hot week or a dry spell starts curling leaf edges. Potassium drives water regulation through the stomata, so extra K plus seaweed during those stretches makes practical sense. It runs from the rooting stage right through fruit and flower, and it works in soil, coco and hydro alike. Keep an eye on the total potassium you are feeding. Stacking it on top of a heavy PK booster in late bloom can push EC higher than the plants need. Unlike a straight seaweed extract, this one moves the numbers on your meter, so log the reading after mixing. The small jar suits a tent or two, and the mid-size jar carries a small room through a full run. The bags are for commercial rooms mixing batch tanks. Store it sealed and dry, since soluble kelp powders cake when they sit in a humid mixing area.
