Still alive!

These easy-to-use packets are the best at eliminating gnats and work really well. Have ordered it thru Amazon and Walmart and received expired product. So glad to have ordered from you-fresh stuff works best!

So I originally tried to cancel my order and try to use a different drying solution. When I found out the order already shipped I decided to keep the rack and try it.
I must say this drying rack was able to handle my 28 branches with ease. The plant was 95% trimmed before hanging. The rack hung well in a 3x3 and allowed the rack to spin for inspection. Being able to spin means it is on a single hanging point that could cause balancing issues.
Long story short, I am glad I made the decision to keep and use the rack. This was mainly influenced by the return policy requiring a restock fee. I am planning on buying more! The rack worked awesomely and is heavier than expected. I would highly recommend this for the small home grow space.
