Customer Reviews
Decent coco coir, slow delivery
I ordered a few bags of coco coir and some nutrient starter kits. The product quality was solid, just what I needed for my plants. However, the delivery took closer to a week, which felt a bit long, especially since I'm used to quicker shipping from other places. The packaging was discreet, which I appreciated. Prices were competitive, but I wish they could speed up the shipping times a little.
Good quality, fast shipping
I ordered a complete grow kit for my indoor herbs. The website was easy to navigate and placing the order was straightforward. It arrived in about four days, which was quicker than I expected. Everything was well-packaged, and the grow tent and LED grow light were exactly as described. The instructions included were clear, and I had it set up without any issues. I even called customer support about a specific setting on the light, and they were very helpful and knowledgeable. Overall, a smooth experience with good quality products.
Got my new fan
Needed a new extractor fan for my grow room. Found a good one here. It came pretty fast, like three or four days. Works great, much quieter than my old one. Happy with it.
Love my new grow lights!
Just received my new LED grow lights and I'm so happy with them! My plants are already looking better. The ordering process was simple and delivery was super quick. I will definitely be buying more from here soon. Highly recommend to anyone looking for quality gear!

Are the grow tents they sell actually discreetly packaged? Don't want my nosy neighbours knowing what I'm up to lol.
Trying to figure out the best way to pay. Do they take PayPal or is it just card payments?
Anyone know how long delivery usually takes to, say, Manchester? Need some stuff kinda quick.
Hey, thinking of getting a full grow kit from these guys. Anyone know if their LED lights are legit brands or some generic knock-offs?
