Herbs, greens and vegetables grow fast and get harvested young, so they draw on nutrients heavily through a short season. Our Liquid Plant Food is made for exactly that, in soil, countertop pod gardens or a hydroponic reservoir, one feed that covers a basil pot and a tray of lettuce without separate products for each.
In a pod garden or hydroponic reservoir the water supplies everything the plant gets, and in soil a container watered daily runs short soonest. Either way, the feed in the water is what the plant has to work with.
Our formula pairs nitrogen with phosphate and a larger share of potash, plus calcium, magnesium and micronutrients, in a balance made for edible plants in soil or in water. It is the same bottle whether the roots sit in potting mix, a pod sponge or a reservoir.
Mix at the rate on your bottle every one to two weeks for soil, or dose a pod system at the start and every two weeks by the number of pods, as the bottle directs. Shake before use, keep the solution between pH 5 and 6 as the bottle recommends, and resist overfeeding.
Why growers choose it: One edible-plant feed that works in soil, pods or hydroponics, with the dosing printed for each.

Don't use a soil-drench dilution automatically in a hydroponic reservoir. Follow the correct labeled system-specific instructions, and check pH and watering before increasing fertilizer.
leafy greens
Supports lush, healthy leaf development for fuller, better-looking greens.
new growth
Encourages fresh leaf and stem growth for actively growing herbs and edible plants.
healthy fruit
Supports healthy fruit development for productive, thriving tomato plants.

Liquid Plant Food is a complete feed for edible plants: a 4-3-6 formula with calcium, magnesium, sulfur and micronutrients, so one bottle covers what a herb or vegetable needs to grow and crop. Use 1 teaspoon (5 mL) per quart of feedwater every week or two, whether you’re growing in soil or in a hydroponic reservoir. Countertop pod systems have a simpler dose by pod count, covered below.
Fast-acting, and in hydroponics that’s the point. The nutrients are fully dissolved in the feedwater, so the roots take them up immediately; there’s no soil to hold anything in reserve, and a slow-release product has nothing to break down in. In soil it works the same way: a measured, ready-to-use dose each time you feed.
Dose by pod count: 5 mL (1 teaspoon) for 2–3 pod models, 10 mL (2 teaspoons) for 6–7 pods, and 15 mL (3 teaspoons) for 9–12 pods. Add it when you fill the reservoir, then again every two weeks. Because it carries the calcium, magnesium and micronutrients that fast-growing herbs and greens draw on, it’s a complete feed for the system rather than an add-on.
No. Liquid Plant Food carries calcium and magnesium in the formula, along with sulfur, boron, copper, iron, manganese and zinc. Calcium and magnesium are exactly what a separate Cal-Mag supplies, and growers add one because many base nutrients leave them out. This one doesn’t, so a single dose covers the base feed and the Cal-Mag together.
Run the reservoir at 5.5 to 6.0. In that range the nutrients in the formula stay dissolved and available to the roots; drift higher and some of them, iron in particular, become harder for your plant to take up. Check pH after you’ve added the feed, since the solution shifts the reading, and keep to the dose rather than adding extra to push a slow plant.
Yes. It’s formulated for edible plants: herbs, greens and vegetables in the garden, in an AeroGarden or in another hydroponic system. The 4-3-6 balance supports leafy growth and fruiting alike, so it carries a crop from seedling through harvest.
