Green House Powder Feeding comes as a dry base nutrient — powder you mix yourself, not a bottle of ready-made liquid. That keeps freight and storage cheaper than the same volume of liquid feed, and a sealed container lasts indefinitely.
What we stock today is the Grow Nutrient, in 125g, 500g, 1kg, 2.5kg and 25kg — a trial pack through to a commercial sack. Weigh the dose instead of scooping, and dissolve it fully before the mix reaches a pump or dripper. Digital scales keep dry nutrient repeatable.
The rest of the Green House Feeding range is not currently available. See Hydroponic Nutrients for stocked alternatives.
