Is there a question here? Seeking critique?
I tell you what i see:
You started out by posting a well filled out support ticket. Thats awesome! The guys on here will be able to help you out with issues better because of that.
Your using happy frog. Also excellent. This means you wont need any nuted for first several weeks(4 or so. But this varies)
Fabric pots are also a excellent choice. 5 gal size should be good. These will help keep you from using too much water. In my experience i can get a little bigger plant to grow in fabric vs clay pots.
Environment looks good for this stage of grow. As the grow progresses your gonna want to start creeping that humidity down some. Google a vpd chart for cannabis.
PH could come up a bit, i like 6.5 to 6.8.
Looks like a decent light. Im a LED guy so ill keep most of my thiughts to myself just because its not something im up to speed on. I will say its not going to be enough to flower out 7 healthy plants efficiently. My guess would be 4 tops but like i said i havent used that light so maybe @dbrn32 can contribute here.
6… get a tds meter and learn how to use it. It will come in handy. Maybe not on first grow just because of info overload but a skill that a good grower should have.
That ac is for the whole garage yes???
Those are my thoughts. Overall looks like your off to a good start. Better than most.
Water is your best freind and worst enemy. Too much is bad and not enough is bad, however too much is worse than not enough. (Wow that was a real stoner way to word that huh?).
Patience, patience, patience. You will make mistakes. Dont let them get you down, the best growers on here foul up plants all the time. Whenbyou make a mistake come here and tell everybody exactly what you have done and they will help you out and quick. We are on this thing around the clock!
Last but not least, remember god gave us weed so we could heal ourselves mentally and physically. Every time a mistake gets you down, burn one and smile about it. This is the most fun you can have growing anything… except maybe children but they are the reason most of us started smokin in the first place. Lol
Damn, sorry for such a long post… im so high rite now…
