Same product diff name

Sunritek from a overseas company same as every company making any light has much more spectrum options and purchase options.

Questioned my purchase

I appreciate Kumans for reaching out to make sure my order was correct. I ordered a odd item and understand why the reached out. I give them an "A" on customer service.

Athena IPM

Now that’s the ticket!!

After mosquitoes made their homes in one of my indoor plants, the baby mosquitoes were everywhere and uncountable. Whithin24 hours of using IPM as directed, not only where their no longer any bugs in the plants but the entire house was bug free!!

Great service

As described, fast shipping. Good product. 👍
