Grow Challenge

Cannabis Grow Challenge Grow Along

The Coco for Cannabis grow challenges are not competitions! Our goal is to bring new and experienced growers together in the spirit of collaboration. We welcome all growers! There is always a ton to learn when dozens of friendly growers grow along together. We love to compare different media, lights, nutrients, and strategies. Whether you are a new grower looking for guidance, or an experienced grower looking to share knowledge, we would love to grow together with you in our Cannabis Grow Challenges!

The Annual Coco for Cannabis Grow Challenge Calendar


Announcing the 2019,

Beat "The Best" Challenge!

The Beat "The Best" Challenge (BTBC) is a collaborative grow event. We have Photoperiod and Autoflower divisions and as a community we vote for one strain to be selected as “The Best”. The plan is for everyone to grow "The Best" strain along with other strains that they think might Beat the Best! Each grower will be in charge of calling their own winners and we will keep track of how "The Best" stacks up with the rest. We plan to germinate on the same day and grow together using the forum and chatroom. It will be a lot of fun - All the grows will have something in common and something unique! We hope that you grow with us in the BTBC!

Germination Date: August 15, 2019
