Welcome to Horizen Hydroponics! Now Offering Free Shipping on Orders over $150!

Shipping & Returns


Horizen Hydroponics typically uses UPS Ground or USPS Priority mail to deliver products for the contiguous 48 states. For Hawaii, Alaska or international the shipping price may vary due to the methods of delivery to that area. The website will not charge shipping for international orders or orders weighing over 150 LBS. Please contact us for a quote for bulk or international orders. Also note that UPS will not deliver to a P.O. Box. Please contact us if you have any questions regarding shipping or would like a quote.

Due to the amount of internet fraud, we will only ship credit card sales to the billing address of the card holder. We also require a valid contact (phone number or E-mail address) to fulfill orders. Please call us if you would like to place an order to a different address. We apologize for any inconvenience.

*IMPORTANT: We try our best to get same day orders processed if the order arrives in time for processing. However, when selecting Next Day, 2nd Day or 3 Day shipping options, please be advised that these options are promised from the time of shipping, not from the time the order was submitted. Please understand that it takes time to process the payment, pick your order from the warehouse, properly pack it in a box, label it and get it ready for shipping. If an item is out of stock, we will contact you with an expected shipment date.

*All of our orders are shipped in plain brown boxes or generic USPS mailers.

Orders are processed Monday through Friday. Orders placed over the weekend will be received and processed on Monday.


Free shipping is for ground shipments only. Expedited shipping is available on free shipping items. The cost difference between standard ground shipping and expedited shipping will be the customer’s responsibility if requested.

Special order pricing includes a special handling fee. They are only returnable if the item arrived damaged or if the product is defective. Also, we should add that tracking information for special orders is not emailed, but is available upon request.

If no comparable product is available, we will promptly refund your money.
