Hello all, I have actually not ordered my Grobo YET , but the only thing stopping me is one concern. I saw that the Grobo Premium runs on nutrient bottles like other boxes . Is a good cannabis grow absolutely dependant on having those nutrient bottles filled? If so , I am kind of concerned about what if Grobo did go belly up, or somehow lose capability to produce them, would I then be stuck with a 2300.00 dollar paperweight?

My common sense kind of tells me that it shouldn’t be THAT hard to find out what goes in the bottles and refill them with stuff ordered from a third party , or even buy the nutrient bottles from another company. So is this the case? Will I be able to run this thing and have good grows no matter what? Cause if so, I will place my order for one today and will be on here talking about my first grow very soon. Thank you in advance for any help, sincerely, a total newbie to growing.

The truth is that Grobo feels the ingredients of the bottles are proprietary and ONLY suggest using their products to avoid “clogging” of the feed lines. I thought about this too when I purchased but worst case scenario you can add your own nutrients weekly and run the machine that way by bypassing their dosing.

Grobo has stated that if the company closes they will still have a business model selling nutrients. I wouldnt be too worried about it.


Hey @Jc1,

I’ve responded to your support ticket too.


Check out this article Bjorn our CEO wrote recently.
It’s not rocket science, all plants want nitrogen, phosphorus and potassium.



Honestly I am now gravitating towards a super closet, same price tag, ungodly difference in space so I can grow plenty, seems it would be tall enough for autoflower sativa strains with some training, hydro root feed all I have to do is buy nutes anywhere and add them to my water ( Which it actually does for me ) it comes with a drying tent and a cloning station and dual grow chambers built into it for a continuous cycle, I am seriously hard pressed why I wouldn’t pick the SC .
