Product description
Plagron Alga Grow 500 ml – organic NPK 4-2-4 grow nutrient for soil
Two tents running, or one tent that never stands empty? The 500 ml bottle is the size for growers who already know they like feeding organically in soil. Plagron Alga Grow is an algae-based base nutrient for veg with NPK 4-2-4 and micronutrients. Organic nitrogen, amino acids and proteins drive green growth and root development, and the marine algae extracts help plants stay steady when it gets dry or hot.
How many litres you get
500 ml at 4 ml per litre gives about 125 litres of feed water. In practice that covers the veg stage of a couple of runs in a medium tent, or one run across two tents.
In practice
At this scale most growers mix a full reservoir or a 10 L can at once: that's 40 ml per fill. A measuring cup with ml marks is quicker than a syringe here. Feed at every watering in veg, from day one on Lightmix and from week 2 on Growmix. In 100% NATURAL substrates pH and EC can stay as they are. Keep the bottle closed and cool between runs, and don't worry about a light smell after mixing.
