One Bottle, One Measure, Through the Whole of Veg
Ionic Hydro Grow is a single-part base nutrient for hydroponic systems in soft water areas, formulated for the vegetative stage. Every element the plant needs during veg is already balanced in the bottle, so there is no A and B to weigh against each other and no sequence to get wrong when you mix a tank. It works across recirculating and run-to-waste systems and in inert media such as clay pebbles and rockwool. Stocked in 1 litre, 5 litre and 20 litre sizes.
Key Benefits
- Single-part simplicity - one bottle and one measurement per reservoir, which is far harder to get wrong.
- Soft water formulation - built for supplies that carry little background calcium and magnesium.
- Veg balanced - a nitrogen-led ratio aimed at strong leaf, stem and root development.
- Works across systems - suitable for recirculating tanks, run-to-waste and inert media.
- Three sizes - 1 litre, 5 litre and 20 litre to suit anything from a tent to a large room.
The Trouble with Mixing Two-Part Feeds
Two-part feeds are kept apart for a reason. Tip the concentrates together and the calcium in one meets the sulphates and phosphates in the other, and you get a chalky precipitate that settles on the tank floor instead of reaching the roots. It is an easy mistake in a hurry, and the plant pays for it a fortnight later. A one-part feed removes that failure mode entirely.
How to Use
- Fill the reservoir with fresh water and note the starting EC.
- Add Ionic Hydro Grow to circulating water and stir it through.
- Check EC, then adjust pH once the solution has settled.
- Feed through the vegetative stage, refreshing the reservoir rather than endlessly topping up.
- Change to a bloom formulation as flowering starts.
