Soil & Soilless Nutrient Packages
Nutrient packages bundle the core products of a complete feeding program -- base nutrients, additives, and supplements -- into a single kit at a reduced price compared to buying each component separately. For growers starting a new feeding program or transitioning between nutrient lines, a package provides everything needed to run the system from the first feed through harvest, with compatible products from the same brand that are formulated to work together. General Hydroponics Flora Series packages, Emerald Harvest kits, and similar offerings cover the full cycle without requiring individual product selection.
What to Expect in a Nutrient Package
Most packages include a two- or three-part base nutrient (grow, bloom, and micro or A/B parts), a Cal-Mag supplement, and one or more additives (root stimulant, bloom booster, finishing product). Complete packages from General Hydroponics cover the vegetative and flowering phases with a single purchase. For growers using RO or soft water, verify that the included Cal-Mag is adequate for your water source -- RO programs often need additional calcium supplementation beyond what a standard kit includes. Package sizes range from small (sample/trial formats) through large gallons appropriate for a full season of feeding.
Selecting the Right Package
Choose a package based on your growing method (soil vs. hydroponic), water source (soft/RO vs. hard tap), and production scale. Soil packages typically use lower-EC formulas and include organic or organic-hybrid products appropriate for soil microbiology. Hydroponic packages are formulated for direct root zone delivery in inert or soilless media. Browse all nutrients or explore individual product lines from General Hydroponics.

Nutrient Packages FAQ
Is a nutrient package better than buying products individually?
Nutrient packages offer two main advantages: cost savings (brands typically discount packaged kits 10-20% versus individual product pricing) and guaranteed compatibility (all products in the kit are from the same brand and are formulated to work together without precipitation or interaction issues). The tradeoff is flexibility -- packages lock you into one brand's ecosystem, which is the right choice if you want a complete, supported feeding program. For growers who are building a custom program from multiple brands or who already have components of a system, buying individual products gives more flexibility to match components to specific requirements.
Can I use a hydroponic nutrient package in soil?
Most hydroponic base nutrients can be used in soil at reduced rates, but they are formulated for direct root-zone delivery in inert media where pH and EC are the primary variables -- they lack the organic matter and beneficial microbiology that soil-specific formulas are designed to work with. Using a hydroponic formula in living soil may suppress soil microbiology, particularly the beneficial bacterial and fungal populations that cycle organic nutrients in amended soil. For soil growing, use soil-specific or organic-compatible nutrient packages from brands like Fox Farm, Roots Organics, or General Organics rather than hydroponic-formulated products.
What size nutrient package do I need for a 4x4 tent?
For a single 4x4 tent through a full growing cycle (8-12 weeks vegetative plus 8-12 weeks flowering), a small to medium kit is typically sufficient. In coco or rockwool, a 4x4 tent with 4-9 plants may use 1-3 gallons of base nutrient concentrate per cycle depending on feeding frequency and canopy size. "Small" packages (quart sizes) are adequate for a few cycles in a single tent; "large" or "complete" packages (gallon sizes) cover multiple cycles or larger operations. General Hydroponics Flora Series kits, for example, come in small (quart) and large (gallon) formats -- the small kit covers 1-2 full cycles in a typical 4x4 tent.
