High nitrate nitrogen, low potential acidity fertilizer. Enhanced magnesium and sulfur levels can reduce the need for epsom salts. Good for use when cool, dark growing conditions are prevalent and no additional calcium is required. The additional level of micronutrients provides necessary elements absent from most commercially made peat-lite potting media.
For use on: Great for all crops, especially poinsettias and geraniums, tropicals like hibiscus.

The ideal fertilizer for encouraging overall healthy plant growth, a strong root system, and rapid development of all plants. Its high phosphorus content encourages rapid root generation which eliminates transplant shock when used as a transplanting solution.

You've always been told to finish strong. This formula is ideally formulated for this purpose to provide your plants with a very low nitrogen, high phosphorus and very high potassium content to keep the whole plant happy to the end of its crop cycle.

Get ready for a serious boost of available phosphorus. The primary goal of this formula is to assist in shutting down the strong vegetative growth stage of the plant and stimulate a switch to the reproductive or flowering phase of plant and flower development.

An improvement on the classic "Part A" formula for general vegetative growing. This redesigned blend is built with purely soluble and available nutrients to allow the grower maximum flexibility. Specific balance of macro, secondary and micronutrients delivers an efficient combination of nutrients suitable for many different growing environments and crop types.

This combination of nutrients will lower pH over time while including the extra soluble calcium, magnesium and the right balance of micronutrients.

For the Purest in you. This one part nutrient blend is designed for crops grown in very low alkalinity waters such as reverse osmosis (RO) water, rainwater, and distilled water. Formulated utilizing the innovative raw materials to reduce pH crash while delivering all the nutrients essential for vigorous plant growth.

Greenhouse grade: fully water soluble nitrogen, potassium and calcium fertilizer.
