Seaweeds | Kelps

Kelp has long been prized by gardeners for its powerful micronutrient content and natural plant hormones. Kelp can come in many forms, but overall is a great, all purpose supplement to boost growth and provide a range of micronutrients, vitamins, and minerals. Kelps can come either from kelp farms or harvested naturally from the ocean, either way it makes a great fertilizer. HTG Supply carries kelp from top brands like Age Old, Maxicrop, General Organics, Roots Organics, and more! Shop today and put that green seaweed to work.
