Thank you for your interest in our products. We ship samples to qualified grow operations who want to try out our products. To simplify the process, we have setup these sample packs that you can order for free, just pay for shipping. We ship via UPS and rates are calculated at the time of checkout based on delivery location. Please choose the pack or packs that work for you and order them. Packages normally ship within 2-3 days of ordering. Limit 1 of each pack per customer. We reserve the right to cancel sample requests!
