NFTG Herculean Harvest
Best soil supplement for growers seeking stronger stems and enhanced flavor.
Herculean Harvest is a powerful plant supplement designed to enhance strength, structure, and flavor in your crops by increasing the availability of phosphorus and calcium within the soil food web. Its active calcium phosphate content transports essential nutrients to the plant, excluding only nitrogen and potassium. This calcium promotes robust stem development through stronger cell creation and boosts the soil's cation exchange capacity, making existing nutrients more accessible. Using this supplement is also beneficial for flushing salt buildup from potting mediums, leading to improved size, aroma, and flavor in your final harvest.

Know before you buy
Yes, this supplement is designed to be compatible with any nutrient program. It functions as a phosphorus and calcium booster rather than a complete base fertilizer.
Herculean Harvest aids in flushing excess salts from potting mediums by improving the soil's cation exchange capacity. This helps prevent nutrient lockout and keeps your growing medium clean for better root health.
By increasing the availability of phosphorus and calcium, the supplement supports healthier plant development and more efficient nutrient uptake. This often results in improved size, aroma, and flavor in the final product.
No, Herculean Harvest is specifically formulated to provide calcium and phosphorus. It does not contain nitrogen or potassium, allowing you to control those levels independently through your base nutrients.
The active ingredient is calcium phosphate derived from bone meal. This provides a quick-release source of nutrients that are readily available for your plants to uptake.
Herculean Harvest is specifically recommended for use in potting soil or soilless growing mediums. It is not designed for use in recirculating hydroponic systems, as the organic components may clog irrigation lines.
