LetPot Hydroponic Plant Food Nutrients

Our take on the LetPot Hydroponic Plant Food Nutrients

A two-part liquid nutrient set for LetPot hydroponic gardens, sold as two 100 ml bottles (A and B) that you dose into the water reservoir. It is a small refill-sized kit rather than a full season's supply, so heavy growers will reorder often. At $16.99 at LetPot as of November 7, 2026, it is the only new price listed, so there is no cheaper store to compare against.

Questions and answers

How much nutrient do I add per reservoir?

Dose per the LetPot garden's instructions, usually a small measured amount of A and B per liter of water. Mix A into the water first, stir, then add B.

How long do two 100 ml bottles last?

It depends on reservoir size and how often you change water. Small units typically get a few weeks to a couple of months per set; larger gardens go through it faster.

Can I use this in a non-LetPot hydroponic system?

It is formulated for LetPot gardens, but the A/B liquid approach works in most recirculating hydroponic setups. Follow your own system's dosing rates rather than LetPot's.

Is this the same as fertilizer for soil plants?

No. It is a hydroponic nutrient mix designed to dissolve in water, not a soil fertilizer. Use it in water reservoirs only.

When is the price lowest?

Only one new price is listed: $16.99 at LetPot as of November 7, 2026. Watch for multi-pack or refill bundles, which usually lower the per-bottle cost.
