DrBinocanswered grow question 5 years ago I can't give you all the advice you'll need but as a fellow newbie I can say the pH meter you have was awful for me. The pH kit you have comes with drops you can use that are just as good - but I ended up buying a better one from a local grow shop. Also some of the fans you have are battery powered - maybe not intentional, and the medium/soil seems expensive - probably can get it cheaper locally? Also depending on how you're starting you might not need it all day 1.
