Beanstalk makes dry, water-soluble salt fertilisers rather than pre-diluted bottles. You mix them yourself, which means you are not paying to ship water and you have direct control over the NPK ratio at every stage. For growers comfortable with a set of scales and an EC meter, it is the cheapest way to feed a room properly.
The range
- V-Basis (14-4-12) – the nursery and vegetative base. High nitrogen for leaf and structure.
- Absolute Flower (11-3-17) – the flowering base, shifted toward potassium.
- K-Boost (1-0-31) – almost pure potassium, added late in flower for bulk and ripening. See flowering boosters.
- CA-Fortify (12-0-0) – calcium and nitrogen, for coco and RO water. See CalMag supplements.
- One Pot Pack – a pre-measured set sized for a 15L pot, which is the easiest way to try the system.
Why dry salts?
| Dry salts | Bottled liquids | |
|---|---|---|
| Cost per litre of feed | Very low | Higher – you are shipping water |
| Shelf life | Years, sealed and dry | Limited once opened |
| Control | Complete – you set the ratio | Fixed by the manufacturer |
| Effort | Weighing and dissolving | Pour and go |
| Storage | Compact | Bulky |
What you need to run them
Accurate scales and an EC meter, not optional. Dry salts are concentrated and there is no dilution buffer – weigh, dissolve fully in warm water, then check EC before it goes near a plant. See pH and EC management and beakers, jugs and syringes.
Dissolve each component separately before combining, and add calcium last – calcium and phosphate salts will precipitate out if they meet in concentrated form, exactly as they do in a two-part liquid feed.
Who it suits
Growers running more than one tent, anyone tracking EC rather than following a chart, and people who have got tired of paying courier rates on water. If you want a simpler route, a bottled nutrient starter kit or a standard base nutrient will get you to the same place with less arithmetic.
