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.


Discount Coupon Codes

We are running a store-wide discount to celebrate the start of 2019! 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)
  • Sasquash Rosin Presses
  • NugSmasher Rosin Presses

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.

Brand Discount Coupon Code
NextLight 15% off next15
Black Dog LED * 10% off black10
Lush Lighting 10% off lush10
California Lightworks ** 12% off cali12
Kind K5 Series 15% off kind15

* Discount NOT applicable to the Phytomax-2 200 (only PM-2 400 - PM-2 1000).

** Discount ONLY applicable to the SolarSystem Series.

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.


Generally, our best coupon codes are distributed exclusively through the Grow Light Central email newsletter. If you would like to sign up, use the signup form in the footer of this webpage.

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

You will also receive exclusive new codes regularly via email. Most of these discounts are only available to our newsletter subscribers.
