Product description
Plagron Alga Grow 1 L – organic base nutrient for the veg stage in soil
For most home growers the litre is the sweet spot: enough to stop reordering every run, small enough to use up while it's fresh. Plagron Alga Grow is an organic, algae-based grow feed with NPK 4-2-4 and micronutrients. Organic nitrogen, amino acids and proteins support fast green growth and a strong root system, while marine algae extracts help your plants through dry spells and temperature swings.
One litre, 250 litres of feed
At 4 ml per litre (1:250) a full bottle turns into roughly 250 litres of nutrient water. Depending on pot size and plant count, that keeps a small grow room or a pair of tents fed through veg for several runs.
Why growers stick with it
It is simple. One feed, one dose, added to every watering during veg. On Lightmix you begin straight away, on Growmix from week 2. Growing in 100% NATURAL substrates means no pH or EC adjusting. A dosing cup is fine at this size, but mark 4 ml and 40 ml on it once and you'll never need to think about it again. The product is for soil only; if you run it through drip lines, flush them afterwards.
