Foop Organic Liquid Compost is a liquid plant food made from fish manure, fish emulsion, sea kelp, volcanic ash, and mycorrhizal fungi, supplying nitrogen, phosphorus, potassium, calcium, magnesium, and silica in one application. It's used to feed plants directly and support long term soil fertility for vegetable gardens, hydroponic systems, houseplants, and outdoor landscaping.
This product suits gardeners looking for a complete organic nutrient source rather than a single nutrient fertilizer. One honest note up front: as a fish based formula, it carries a noticeable earthy, marine scent during and after application, which is part of the natural ingredient profile rather than a sign of anything wrong with the product.

Best Suited for Establishing New Transplants and Feeding Plants Under Stress
If you're replanting or transplanting during hot summer months, this liquid compost is formulated to help plants establish root growth quickly when they're most vulnerable to heat stress. It works across indoor and outdoor settings, including hydroponic systems, giving you flexibility whether you're feeding container vegetables, garden beds, or houseplants.
Because it's a liquid concentrate, you apply it through regular watering or spraying rather than working it into soil, which makes it a fit for ongoing feeding schedules rather than a one time soil amendment. If a strong scent in your immediate growing area is a concern, outdoor use will generally suit this product better than tight indoor spaces.
What to Expect from Foop Organic Liquid Compost in Real Use
Across reported use, this liquid compost performs well for plant health and growth, particularly for vegetables, hydroponic setups, houseplants, and transplants needing to establish roots under heat stress. Owners describe noticeable improvement in plant vigor and growth, including over extended use periods on houseplants lasting more than a year.
It's credited with helping revive plants that had struggled after replanting or exposure to harsh summer temperatures. The most consistent point of feedback involves scent. Because the formula includes fish manure and fish emulsion, it carries a strong, lingering smell during and shortly after application, with several owners specifically noting it's better suited to outdoor use than near indoor living spaces.
Package size also comes up, with some owners noting the smaller quart size feels limited for their needs relative to how much product a full feeding schedule requires.

Frequently Asked Questions
Why does this fertilizer smell so strong, and does the smell go away?
The scent comes from its fish manure and fish emulsion content, which are key sources of the nitrogen and complete nutrient profile the product delivers. The smell is strongest immediately after application and can linger in enclosed or covered outdoor spaces for several hours.
If scent is a concern, applying it in open outdoor areas rather than near covered patios or indoor spaces, and watering it into soil rather than leaving it on surfaces, will reduce how noticeable it is over time.
Is this fertilizer suitable for use on indoor houseplants?
It can be used on indoor plants, and several owners report strong long term growth results doing exactly that. However, because of the fish based scent, applying it in a well ventilated area or temporarily moving plants outdoors during application and for a few hours afterward will make the experience more pleasant indoors. If strong smells in your living space are a dealbreaker, reserving this product for outdoor or garage grown plants is a reasonable alternative.
Does this fertilizer work for hydroponic growing systems?
Yes. As a liquid concentrate with a complete nutrient profile, it integrates into a hydroponic feeding routine to supply nitrogen, phosphorus, potassium, calcium, magnesium, and silica directly to plants without soil. This makes it suitable for hydroponic vegetable growing where consistent nutrient delivery through the water system is essential for plant development.
