Welcome to Greens Horticulture
Greens Horticulture has been supplying growers in Bristol and across the United Kingdom since 2003. As one of the longest serving and most trusted grow shops in the UK hydroponics industry, we are the grow shop of choice for thousands of indoor gardeners each and every month. Unlike other grow shops, we've built our reputation by focusing on products that produce great results time after time for our customers — not on what makes us the most profit.
We offer an industry-leading 14-day no-quibble money-back guarantee on all products, except nutrients or bags of growing media that have been opened. If, for whatever reason, you are not happy with your purchase, just return it to us and we will refund the cost of the item — no questions asked.
Order before 2pm and your parcel ships the same day, Monday to Friday, with Parcelforce or DPD Local. We email or text you the evening it leaves us, and again on the morning of delivery with an expected time. Standard UK mainland delivery is £6.95, and free on orders over £90.
