Delivery, returns and FAQs

Will my order arrive in plain packaging?

Yes. Every order is sent in plain, unbranded packaging as standard.

How quickly will my order arrive?

Order standard size items by 12pm on a working day and choose Next working day at checkout, and your order will be with you the next working day. Standard delivery takes 2 to 3 working days.

Bulky items such as grow tents, large fans and 50L bags of soil go by courier in 2 to 3 working days, or on a pallet for very heavy orders. Next day is not available for these, and if your basket includes a bulky item the whole order travels with it.
