You have a sweet list here. Sounds like my ideal room.
I have a few things I would like to note:
Portable AC- many have a dehumidifier built in so you may not need that.
Happy Frog- I use Roots 707 for a base, add earth worm castings, perlite, vermiculite, etc. FFOF would work great of course as well. I would get Fox Farm Light warrior for seed starting unless you are using rapid rooters, or rockwool, etc... I have never used happy frog, and sounds like reaver knows about it.......
Flourescent fixtures- flourescent tube fixtures (48") can usually be found used or free(except for the bulbs), take a look around.
Bag pots- drain fast, definitely need something to catch water when it comes out. I got those things you put under house plants from the dollar store (1 dollar for 2-5 of them depending on size)
Nutrients: Didn't see a new nutrient line in there (saw the happy frog, maybe you already have them): when I started my grow I purchased a shit ton of nutrients..... SOme I haven't even opened yet.... Just wanted to have everything from the start.
6" inline fan/ carbon filter- Is this the fan you are going to use to cool the light as well? THose cheap inline fans won't do anything when cooling 2k, but would be excellent cold air intake and exhausts fans. remember cross flow.
Standing oscilating fans: mount them on the ceiling take up less floor space
Sounds sweet garens bro. This is my first grow, with all the right stuff. previously, I never put a whole lot of money/ time/ effort into it, but expected good results, didnt happen...... but now..... tables have turned....... It all makes a difference.... I tried to keep my budget under what I thought I could yield off the first run, even though none of this is getting sold, it will pay off when I don't have to buy a half ounce a week
Are you building your actual grow room or have a room, or tent?
