Grodan Improved
Uniblock GR40, 8" x 8" x 4"

Grodan partnered with the Wageningen University and Research facility in The Netherlands and top growers throughout North America to identify the optimal stone wool substrate and irrigation strategies for specialty crops. The result of months of scientific research and trials is Grodan Gro-Blocks Improved with Grodan’s Advanced Wetting Agent. 

These leading-edge blocks have the optimal fiber structure and physical properties for crop uniformity, more even Water Content (WC) and Electrical Conductivity (EC) distribution throughout the entire block, and the greatest steering capabilities available. Water distribution is more uniform throughout the entire block which is the basis for a well-defined root system with higher capacities for water and nutrient uptake to produce robust and vigorous crops.

New and improved wetting agent and hydrophilic technology greatly enhances the water characteristics of Grodan Gro-Blocks Improved giving even better water distribution over the height of the block. This results in greater plant development and steerability and more efficient use of water and nutrients.

Optimized wool structure allows for faster rooting-in and nutrient solution replenishment, all while the Gro-Block Improved maintains its structure, firmness, and rigidity throughout the growing process.

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 support@seresag.com 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.

Tracking

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.

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.
