Frequently Asked Questions

All Canadian orders over $99 qualify for free shipping. There are no weight exclusions or restrictions to the number of items ordered. Orders below 99$ will be charged a 15$ flat shipping fee.

We're sorry, but due to the very high cost of international shipping, we can only offer free shipping in Canada right now.

We ship most orders via UPS, Purolator, Canpar, Dicom and Canada Post. While we do our best to get orders delivered quickly, we cannot account for any delays carriers may have. However, if you let us know of a delivery that arrives outside our guaranteed window, we will gladly refund any shipping charges incurred.

Standard/Free Shipping: Packages normally arrive within 1 to 2 business days if you are located in Quebec/Ontario and 3 to 5 business days if you are located in other provinces.

Priority Shipping:

If you want your package a little bit quicker, we offer a Priority Shipping option that will get your package to you in 2-3 business days. 

Our shipping cutoff time is 11AM Eastern Time. So, any order placed after 11AM will ship out the following business day and therefore the day you place your order would not count towards the shipping times above. If you place your order on a weekend or a holiday, please consider the following business day as your first day when factoring in shipping times.

Everyone at GrowBuds is committed to making sure customers are satisfied with our products and happy with their purchases. In the event that your grow tent, LED grow light, bulbs, nutrients or other products are not what you expected, you are free to return it within 30 days of your purchase date, no questions asked. We keep things simple because we know what it’s like to be in your shoes. When we purchase from online companies, we too expect a simple return policy that does not confuse or frustrate us.

So just how can we do this? That answer is easy. GrowBuds is comprised of the highest quality products on the market. We take great pride in our merchandise and are very confident that customers will fall in love with our products just as we have. That said, we can deal with a few outliers that happen to be returned.
