Fascinating lol just read thru that whole thread. If you wouldn't mind posting some updated pictures of all the feeder breedings you got going on that would be awesome
If you don't want to get them online then next option would be local pet shops. The pet shops ive gone to charge more for hornworms then online shops. I feel like the extra charge compares to shipping fees. I usually add a couple other bugs when I order hornworms to make it worth the shipping...
I had a sansi grow light and plants did well I will say from my experience I got better results from the Arcadia light which is what I'm currently using and will continue to use in the future. If the funds are available I personally would say arcadia.
