Great job.

Welcome to the forum @alexford I think you will like this place 
Yesterday. I finally got a nice day in the grow room. A few more days like this and I should see some nice growth.
This was towards the last 2 weeks of my grow. I like it cooler for my ladies during that time. The vent was actually directly connected to the air flow from the central air so it helped drop the humidity and temp.
I know this is an older thread, and I didn’t go through all of it so this may be a repeat.
My water has all kinds of crap in it. Amazon RO BUDDY Has made my life so much better. We even use it for most of our consumption needs.
I have a friend who grows in a cabinet, he only has about 40" height, then 6’ x 18", he grows some killer weed.
Incredible shot above the 50th parallel!! 
I started with a closet I lined with space blankets and a grow light…it worked. I have upgraded to a tent with a filter, better lights, and this year I added a heater so I can grow all year. We all started somewhere. I actually still use the closet for starting my plants, so it isn’t a waste.
Outstanding…
I’ve seen hella worse…
At least you’re not using… (HaHaHa) “Miracle Grow”…
