Botanicare® Cal-Mag™ Plus is a highly fortified calcium, magnesium and iron plant supplement formulated to correct common deficiencies. Supplementing your preferred nutrient program with Cal-Mag Plus is strongly recommended when using reverse osmosis water and when growing in coco coir-based medias to compensate for natural calcium draw. Cal-Mag Plus can also be applied as a foliar spray to further enhance growth.
Diamond Nectar® accelerates nutrient absorption where mineral foods enter the plant. Diamond Nectar applies the chelating action of humic acids to nutrient rich hydroponic environments by grabbing immobile and molecularly heavy compounds. They are transported through and into plant tissues for faster growth and greater yields. Diamond Nectar supercharges your nutrients to optimize the health of your plants and the quality of your crops.

Terpinator® is the original terpene and resin enhancer. Formulated to help provide the building blocks for secondary metabolites, Terpinator® feeds to encourage increased production of terpenes to help heighten aroma and flavor. Terpinator® can be used in conjunction with General Hydroponics® nutrients or any feed regimen and is compatible with soil, hydroponics, and soilless media.
Designed to help enhance the expression of purple in capable cultivars, Purpinator® feeds to help support the increased production of flavonoids (plant pigments) and maintains a neutral plant cell pH. Like Terpinator®, Purpinator® provides the building blocks for secondary metabolites, which helps increase the production of terpenes for improved aromatics and flavors. Use alongside General Hydroponics® nutrients or any feed regimen, whether growing hydro, in soil, or with soilless media.
FloraBloom® Professional contains nutrients providing high phosphorus, potassium, magnesium and sulfur which may stimulate flower and fruit development and enhance flavor, aroma, and essential oils. Combine with FloraGro® Professional and FloraMicro® Professional.
