Very prompt delivery of an excellent product.
The 50 lb bag of CuSO4 fine crystals is what I needed for my aquatic weed control, and the product that arrived is exactly as advertised. The price for the product hasn't gone up, which is appreciated, though the shipping has.
Excellent communication and fast shipping. Would purchase from again.
The copper sulfate came in faster than expected and in good condition, if I even need more I will definitely buy it from here
Fast shipment. Great product.
I appreciate the emails with order confirmation and shipping information including tracking number!
Made a 20% solution for the roof. Sprayed with garden sprayer. Working very well. Some moss turned black in just a few hours. Easy to make solution from the crystals.
Quick accurate well packaged delivery. Won’t hesitate to use Seed World again.
Ordered product from Seed World and received it on time with no problems. Definitely would order from them again.
Just what the doctor ordered
I bought 50 lbs this time, arrived UPS in a timely manner and will be using this for root growth control, I’ve used it in the past and mixed it with root x foaming root killer. Seems to work well.
On time and packaged well. Thank you
Got what I wanted and the service and delivery were very god. thank you!
