Product description
Plagron Alga Grow 250 ml – algae-based veg nutrient for soil growers
You grow in one tent, you like to keep it organic, and you don't want a half-empty can sitting on the shelf for two years. That's where the 250 ml bottle of Plagron Alga Grow fits in. This organic base nutrient for veg (NPK 4-2-4 plus micronutrients) feeds with organic nitrogen, amino acids and proteins, while marine algae extracts help plants handle drought and temperature stress.
What 250 ml gives you
Dosed at 4 ml per litre you mix roughly 60 litres of nutrient water from this bottle. For a typical tent with four to six plants in soil, that usually covers the veg stage of one run, sometimes two if you keep veg short.
Good to know
Add the feed to every watering during veg. Lightmix users start straight away, Growmix users from week 2, because that mix is pre-fertilised. A cheap 10 ml syringe keeps dosing honest when you mix by the watering can. With 100% NATURAL soil you can skip pH and EC correction. It is meant for soil only, not hydro, so rinse any drip line you used it in.
