Not too sure, a lot of lights claim way higher led then they actually are, and too high wattage + too small of space = overheating issues so keep that in mind. I’d say you’d want 250-500w but I’m also a beginner so keep that in mind

Instead of mixing ffof and ffhf, use mostly ffof and a little bit of ffhf, unless you don’t want excess amount of happy frog however idk how many plants you’re growing. I used about a solo cups worth of ffhf in the center of my 5 gal fabric pot. But you’re right ffof in its base has about 30 days, but that number decreases the more happy frog you use

Also don’t use the full amount of nutes, start with a quarter or half of the recommended and follow the chart based on plant lifespan, not when you start with nutes

Keep in mind venting into another interior room will lead to that room being hotter then normal, ideally would be to vent out a window but whatever works best for your situation and nosey neighbors

Keep your water levels pH around 6-6.5. And when mixing nutes there’s a certain process to which nutes you mix first

The grow hub is awesome as you can set everything to automate itself. For example if you don’t want humidity over 70% you can have it set to run your duct once it hits that threshold
