  • Plant Success King Crab increases yields, maximizes phosphorous uptake, and adds life to the root zone. The active microbes in King Crab were specifically selected to enhance root zone performance during the vegetative stage and increase yields in the flowering stage. With 275 million organisms per mL, these microbes enhance absorption of phosphorous and micronutrients, which is key to higher yields and quality flowers.
  • Rock Rootinator fortifies plants against negative environmental stress and helps bring sick plants back to health with its updated version of the classic root boosting Super Charge Root Tonic. This new, concentrated formulation complements your current feed for healthy root systems, protection from negative environmental impacts, and assimilation of nutrients for maximum effect. Rock Rootinator grows bright white roots, thick healthy stalks, and lush green vegetation.
  • Roots Organics Terp Tea Bloom Booster adds a strategic fertility input for your garden. This proprietary ratio of potent ingredients supplements flowering plants in the later stages of development, enhancing blossom vigor. The result of extensive research and development, Roots Organics Terp Tea Bloom Booster helps bring the ratio of potassium and other primary macronutrients into your targeted range to provide Soluble Potash supplementation that boosts harvest quality and yields. Beneficial bacteria are added to enhance availability of plant nutrients and to help plants to resist stress.
  • Roots Organics Terp Tea Microbe Charge delivers beneficial bacteria, mycorrhizal fungi, and a nutrient charge to support vigorous root systems in heavy-feeding, high-yield plants. Recommended for both large and small-scale gardens, this high-quality supplement is simple, effective, and allowed for use in organic crop production. This formula functions as a direct application or, ideally, it can be brewed into a potent tea. Use Terp Tea Microbe Charge as a base amendment to enhance microbial activity, as a part of your regular fertilizer regime, or as a controlled point supplement to enhance plant vigor. This micronized inoculant can be used to amend any potting soil.

To date, since Hydrofarm’s December 2020 IPO, the company continues to roll out impressive products and build strategic partnerships in support of growers. Last month, the company debuted the new Phantom PHOTOBIO TX and T linear LED top lights and announced a new Canadian distribution alliance with Advanced Nutrients through Eddi’s Wholesale, one of the largest wholesale garden suppliers in Canada.
