Amazing pricing for large scale growers. We've received excellent support from Symbiosys Grow Supply in Colorado and their team. Big thanks to their plant pathologist for confirming our Pythium problem and schooling us a bit on how to keep things under control!
Large order (several KG's) delivered next day in Denver, CO. Shipping was same day. Yields are up and the plants seem healthier overall, we are trying to prevent disease at this point rather than fight it after it's already a problem. So far this has been a solid philosophy for our platform.
