My 2 Aurora+ did a lot of work last year, saved a lot of time. Quickened germination times on hot peppers, cukes, tomatoes, squash, herbs, flowers, melons. In my 2 runs so far, with next generation SPROUT, I’ve seen germination times get even faster and more consistent. Basically it’s very simple, put down a pad, throw seeds on , moisten the pad, put another pad on top, moisten that, put in the lid , plug it in . With the new design it is able to handle bigger seeds , currently I have some jackfruit seeds in there. Only thing you need to monitor is moisture level, and progress of seeds. Also has the ability to put another tray on top for another germination area or daisy chain if you have more than one device. Definitely can see the thought behind the next generational improvements, and customer service is top notch, to help you be successful. Just check out on the site the list of all varieties that have benefited from their devices.
