Frequently Asked Questions

What makes this fertilizer hydroponic-specific?

It's designed exclusively for hydroponic culture, unlike a general-purpose formula adapted for hydroponic use. It's described as a classic formula ideal for most hydroponic crops.

What crops is this formula especially suited for?

It's especially effective for most hydroponic crops, especially tomatoes, cucumbers, and lettuce. Those three crops are named specifically in its intended use.

Why does the buffering matter in a hydroponic system?

It's buffered to help maintain correct working solution pH, which matters more in hydroponics than soil since there's no soil chemistry to naturally moderate pH swings. That buffering keeps nutrient availability consistent across the reservoir.

What water types work with this formula?

It's effective for all water types. Its basicity of 215 lbs. CCE with no urea gives it a moderate, broadly compatible technical profile.

What size is this listing?

This listing is a 25lb bag, sized for commercial hydroponic operations feeding tomatoes, cucumbers, or lettuce at scale. Its basicity of 215 lbs. CCE fits a buffered feeding program run continuously across a growing cycle.

How and when should this fertilizer be used?

Mix it into the hydroponic reservoir as your ongoing feed throughout the crop cycle, since its buffering is designed to hold working solution pH steady over continuous use rather than as an occasional correction. It's suited to season-long feeding of tomatoes, cucumbers, and lettuce regardless of source water type.
