Welcome to the community and congrats on purchasing your Grobo, you’re going to love it! First off let me start by saying that I too am a noob, hence the title “first grow ever”. What I have done with my setup and my grow is by no means necessary, in fact some might argue that some of it may be unnecessary, but I think we can all agree that it’s pretty bad ass .
The Grobo is an EXTREMELY capable piece of equipment. What the Grobo team has accomplished thus far is absolutely astonishing and soon with their tireless efforts and the help of this community, they will have their masterpiece! You do not NEED any of the items, additives, or beneficials, that I have added to my system/grow (except for possibly Hydroguard if the water in your unit raises above 73 degrees which is more common than not).
The questions to ask yourself are:
-What do you hope to gain from the growing process and what are your end goals?
-Is this something you are doing simply to produce great bud or is there a deeper interest than simply producing?
-How much effort would you like to put in aside from the minimum work requirements?
The machine is so capable, many get away with little to no intervention and have great results. I on the other hand find it wildly entertaining to tinker, modify, and push the limits of the Grobo and my plant. I am personally most interested in the growing process and seeing how much I can do to produce the most perfect product. I am also very fascinated by the elite/rare genetics (seeds) market. All of these have become absolute obsessions of mine, thus I have gone way overboard and I’m proud of it.
Another grower called @Hellyesshedid put in a ton of effort and came up with this incredibly comprehensive list of “extras” and their purposes, check it out here:
I would be more than happy to guide you based on my recent experience, once you receive your machine shoot me a message and I’ll assist in your setup! Should you have any other questions before then, don’t hesitate to ask!
