Organic Supplements

In this category you will find all our organic Cal-Mags, foliar sprays, kelps, silicas, amino acids, and vitamins. There is a false perception that to boost plant growth, you need to add harsh, artificial chemicals, but that simply could not be further from the truth. Organic supplements exist for a range of applications, and some may even be more effective than their synthetic counterparts depending on their applications. Organic gardeners can grow yields just as big as the people using the specialized synthetics by taking advantage of HTG Supply’s selection of organic supplements. Shop today to find the organics your plant craves.
