I think future grobos should have the locks on the side and not the top to make sure the door stay secured. It also would be cool if the back wall on the left or right corner had a measuring stick design since it’s clear and it would be nice to see what your height of your plant is. Then you can compare it to other grows and know when to start training. i had some other ideas but this is ok for now.
Also a fun idea would be grobo contest where we get multiple groups of growbo owners and all of them would pic the same strain and start their grow on the same day to see who can get the biggest yield.
