Discount Coupon Codes

To use any discount code, enter it into the discount field at checkout. You will find the discount field on the right-hand side of the screen. After entering the code, click on 'apply' and it will be applied to all applicable products automatically.

Note: on mobile, the discount field is hidden, so you will first have to tap on 'show order summary' at the top of the screen.

Coupon Codes For Grow Lights, Rosin Presses, Grow Tents and Trimmers

We are currently running a store-wide discount! The code is:


It gets you 5% off everything in the store, EXCEPT the following products:

  • The new Kind LED K3 Series (for K5 Series, see below)
  • HLG (Horticulture Lighting Group)
  • Optic LED
  • NugSmasher Rosin Presses
  • PurePressure Rosin Presses
  • Triminator Trimmers

The reason the code does not work for these products is that a large discount is already reflected in the listed price.


In addition to that store-wide code, we have a number of special discounts on certain brands.

All links take you to the page showing all products for the respective brands. The links will open in a new tab, so that you can keep this page open to copy and paste whichever code you need during checkout.

    Upon signing up, you will receive a 8% code for almost any product on our site (not valid for Optic, Green Sunshine, Amare, HLG, Scynce, new Kind K3 Series, Gorilla tents, Triminator trimmers, or any rosin presses, due to the already steep discounts on those items).
