Thanks for the positive vibes. I'll do my best to answer your questions.
Yield is a common question and your results will vary, even when you grow the same strain. You will get about the same yield using a seed or a clone. Over time, clones will yield more due to the time saved. (Clones can go straight to flower and save over a month of vegetative growth time) In my testing, I'm constantly pulling 1.5 - 2.5 oz per grow.
There isn't a 'best strain' to use in the Grobo One, it is up to you to decide what you like. Some cropping or topping can increase your yield by filling the entire grow chamber, but Indica, hybrid, auto or Sativa all work well.
I've tested a ton of strains to date. A couple I was impressed with were Pinapple Express by G13 Labs, Original Amnesia from Dinafem and the Chocolate Haze from Royal Queen Seeds.
Can't wait to hear what you are growing in your Grobo One!
