Growers Choice is proud to present the ROI-E720! 

A Next-generation high-intensity commercial horticulture LED fixture. By far, the most powerful LED grow light in its class.

The ROI-E720 has a standard ppf of 1850 umol and a "BOOST" feature that raises the output by up to 2050 umol ppf when used with the Growers Choice master controller (or similar device) for professional cultivators who demand ultimate PAR output.

With unbeatable safety, reliability, savings, and performance, the ROI-E720 is unquestionably the right choice for cultivators who demand only the best.


PPFD charts for ROI-E720 showing Photosynthetic Photon Flux Density (PPFD) values on 5' X 5' grid points. See the grids below to view the uniformity of the large form factor for a more even dispersion of light intensity. 


External Control with the Grower's Choice Master Lighting Controller

The ROI-E720 is controllable with the  Growers Choice Master Lighting Controller and is compatible with most other 0-10v digital lighting controllers. With the GC Lighting Controller, you can set the ROI-E720 to turn off and on at desired times based on a schedule, program sunrise/sunset settings, program dimming options, and set protective fail-safes to dim or turn off fixtures in the event HVAC failure.

The GC Lighting Controller allows you to customize your lighting setup by daisy-chaining up to 100 fixtures per zone. Enabling complete control of your growing environment through precise temperature readings with dual thermal probes and thermal-threshold auto dim-shutdown for additional protection.

Updated 5/1/2023:

Please note that due to the higher shipping costs and larger dimensions of some of our products, our shipping calculator may not always provide an accurate shipping estimate. In these cases, we will reach out to you with an updated shipping quote after you place your order. If you have any questions about shipping costs, please don't hesitate to contact us before placing your order. We apologize for any inconvenience and appreciate your understanding.

Seres reserves the right to notify you of any additional shipping charges. We partner with multiple vendors and locations, which can alter shipping rates. In addition, there are conditions out of our control (rural areas, fuel surcharge, multiple shipments). If this occurs, you will be contacted immediately and have the right to modify or cancel your order for a full refund. 

Address Change / Order Cancellation

If you need to change the shipping address, please get in touch with us at or call 1-877-237-3754

Once the order is shipped, we will do our best to perform an address intercept. You will be charged an Intercept Fee imposed by the shipping carrier. This fee varies from each carrier. Please note not all shipping carriers will accept address intercept changes.

If an order is canceled in transit, you are solely responsible for all shipping charges incurred by the Shipping Carrier.

Shipping charges will not be refunded.


Once an order has been shipped, we will send an email and text message on file with the tracking number. If your order is fulfilled from multiple vendors or locations, you will receive shipment confirmations with tracking for each shipment. 

In addition, you can check the status of your order through the order confirmation email or within your profile page under Track Order.

Freight (LTL)

Scheduled appointments deliver freight shipments. You are responsible for inspecting for damage incurred in transit and signing before the driver leaves. DO NOT accept the shipment if there is any damage. If your freight shipment arrives damaged, contact us immediately.

Once delivered, we cannot reimburse paid freight charges or refund products.

Some restrictions may apply; Hawaii and Alaska do not qualify for free shipping offers.

Damaged Shipment

It rarely happens, but once in a while, products are damaged during Shipping. Therefore, please scrutinize all shipments for damaged or missing items before signing for them (if required).

The shipping carrier is responsible for items damaged during Shipping, which will most often be UPS, FedEx, or USPS. 

If assistance is needed, please get in touch with us immediately. Seres cannot promise refunds or replacements if this is not done within 72 hours. 

By signing your name and accepting shipment for a Freight(LTL) order, you get no reimbursement of freight charges, order costs, or any other charges incurred.

Lead Times

Please note that there is up to a 7-day processing period for orders containing Hawthorne products.


Due to the valuable contents of many products we sell,  the carrier may need a signature upon delivery. Please understand that this is a measure our company took to ensure safe delivery and fraud protection.

Third-Party Carriers will attempt to deliver a signature-required order three times. 

Please follow up with the carrier for assistance if a missed-delivery note is received.

If assistance is needed, please get in touch with us, so we can help contact the carrier. 

Shipping costs will not be refunded for missed shipments.

Seres is not responsible for any missing, lost, or stolen items.

At this time, we do not ship to post office boxes or APO/FPO addresses.
