HTG Supply Portland

HTG Supply is your go-to growing store in Maine. We carry hydroponic and indoor growing supplies from industry-leading brands at affordable prices for a great value. Whether you are a new or experienced grower, we have products for every skill level. Our supplies can be used for many types of plants at any stage of their development, making us a one-stop shop for your growing needs.

By Appointment Only

To Our Valued Growers,

We are sad to inform you of the difficult decision we have made to close our HTG Supply Portland public storefront. Your patronage and loyalty have been greatly appreciated, and we are sincerely grateful for the trust you have placed in us. Our Portland location will remain on Rand Road to continue supplying equipment and replenishables to our commercial clients by appointment.

For hobbyist growers: We want to assure you that our commitment to serving your growing needs does not end here. Our online store will remain available to you, where you can order the supplies that you need from the comfort of your own home. We offer the best selection and pricing online, and we will be launching an all-new website this fall that will provide an even better shopping experience.

For commercial growers: Our dedicated commercial division account managers are here to assist you remotely or on-site with the same unmatched special pricing, service and support you have enjoyed previously. For assistance with your commercial account, or to schedule an appointment, please reach out to us via phone at (207) 899-4387, or email at [email protected].

Again, we want to express our deepest appreciation for your loyalty and support. It has been an honor to serve you and your home gardens, and we will cherish the memories and relationships we have built with you at our Portland store.
