Organic Fertilizers
Organic fertilizers that feed your plants and support healthier soil Organic fertilizers do more than supply nutrients. They also help support soil biology, build organic matter, and improve soil structure over time — creating a growing environment that can improve season after season. Because nutrients are released gradually as materials break down, organic fertilizers often provide a steadier feeding pattern with less burn risk than fast-acting synthetic options. Whether you're...

Water Soluble Fertilizers
Water-soluble fertilizers for soil, hydroponics, foliar spray, and drip irrigation Water-soluble fertilizers dissolve completely in water and are designed for direct delivery to plant roots or leaves — without waiting for soil microbial breakdown. Whether you're looking for a water-soluble fertilizer for vegetables, a complete nutrient program for hydroponics, a foliar spray to correct a deficiency mid-season, or a reliable fertigation product for drip irrigation, every product in this...

Hydroponics Nutrients
Hydroponic growing gives you precise control over every nutrient your plants receive — but that precision only works if you start with the right fertilizers. Greenway Biotech's hydroponic nutrient lineup covers everything you need: crop-specific base fertilizers formulated for your exact plant, calcium and magnesium supplements to prevent deficiencies, chelated micronutrients that stay available across a wide pH range, and bloom boosters to maximize fruit quality and yield. All products ...

Tomatoes & Vegetables
Fertilizers for tomatoes, peppers, eggplant, squash, and every fruiting vegetable in your garden or hydroponic system. Fruiting crops carry heavy nutrient demands: phosphorus for root establishment and fruit set, high potassium through ripening, and steady calcium and magnesium to prevent blossom end rot. This collection pairs our crop-specific Tomato Fertilizer 4-18-38 with the supporting nutrients a complete program needs — Calcium Nitrate, Cal-Mag Plus, Epsom Salt, and chelated micronutrie...

Lettuce & Leafy Greens
Nitrogen-forward nutrition for lettuce, kale, spinach, chard, and every leafy crop where the harvest is the foliage itself. Leafy greens want steady available nitrogen, adequate calcium to prevent tip burn, and magnesium for deep leaf color — without the heavy phosphorus and potassium that fruiting formulas carry. This collection centers on Lettuce Fertilizer 8-15-36 for hydroponic and soil programs, backed by Calcium Nitrate and Cal-Mag Plus for tip burn prevention, and fast organic nitrogen...

Strawberries & Berries
Complete nutrition for strawberries, blueberries, raspberries, and bramble fruits — crops that reward the right fertility program with visibly sweeter, heavier harvests. Strawberry Fertilizer 8-12-32 delivers the high-potassium profile berries want through fruiting, while the acid-loving members of the family (blueberries especially) draw on Elemental Sulfur, Cottonseed Meal, and Ferrous Sulfate to hold soil pH in their preferred range. Boron matters more for berries than almost any other gar...
-
Pepper & Herbs
Balanced, potassium-rich nutrition for peppers, basil, cilantro, and culinary herbs. Peppers set more fruit and ripen with stronger flavor when potassium stays high through the season, while herbs respond to moderate, even feeding that builds oil content without forcing weak growth. Pepper and Herb Fertilizer 11-11-40 anchors this collection with a full chelated micronutrient package, supported by Calcium Nitrate for structure, Epsom Salt for magnesium, and Monopotassium Phosphate for bloom a...
-
Cucumbers & Vines
High-potassium feeding programs for cucumbers, zucchini, melons, and every vining crop that sets fruit fast and keeps producing. Vine crops are heavy feeders with a distinctive preference: they're chloride-sensitive, which is why this collection leans on Potassium Sulfate and Sulfate of Potash Magnesia rather than muriate sources. Cucumber Fertilizer 8-16-36 anchors the program with chelated micronutrients for soil, foliar, and hydroponic use, while Calcium Nitrate and Epsom Salt keep cal...
