I wasn’t able to get any pictures, but when I was over at KnowESys HQ last week meeting with the guys, I got a sneak peak at the next generation Grobot, and let’s just say I think it’s a winner. The new one is considerably smaller and more square-ish than the original.
Not that the original model is any kind of a slouch, though! Mine has been working very well for months now and I have some pretty great data to show for it. Unfortunately, the actual grow has evolved so much, I haven’t been able to consistently measure the same thing for any length of time, so I’m hoping things will stabilize a little in the months to come.
I have to say, I’m not thrilled with these bucket-shaped bulkheads. They’re kind of a pain to install, and if you use E6000 instead of gasket maker, they are not coming off again ever with conventional tools. Also, the hoses slip off fairly easily and seem too thin to adequately circulate the nutrient solution.
