First time grow - checklist - input appreciated

Hello everyone,

I'm getting ready to do my first grow and want to make sure I'm not forgetting anything, yet not buying anything I don't need for my setup.

Grow Tent - Agromax Window Grow Tent - Size Small (22 x 36 x 63)

Light - Pro Grow 260 (Selective Switch)

Grow setup - Bubble Boy Four Banger DWC

Fan - Growbright 6 Inch Clip-On Fan

Carbon Filter - GrowBright 4" Tall Boy Inline Fan & Carbon Filter Combo

Timer - LEDwholesalers GYO2102 Hydroponic Grow Light 24-Hour Timer

Nutrients - General Hydroponics Flora Series QT - FloraGro, FloraBloom, and FloraMicro

Water Testing - HM Digital TDS-EZ TDS Water Quality Tester with Auto-off Function TDS-EZ - General Hydroponics GH1514 Ph Control Kit

For starting Seeds - Hydrofarm Seedling Heat Mat - General Hydroponics Rapid Rooter Tray

Misc - Pair of Rope Ratchets - 1/8" x 8' - 75lb Max Each Ratchet - 8ft Ducting

Am I missing anything?

Will the 4" Carbon filter/inline fan combo be enough?

Is it worth it to get the muffler for the 4" carbon filter/inline fan?

I want to expand to another 4 banger if the light I chose is enough - would I need to make any other changes if I do, or am I good to go?

Thanks for any input!

You mentioned some rockwool as your starting medium. Don't forget to soak your wool in a 5.0PH solution to correct the the PH of the rockwool. And what will be your growing mediuim. If this is your first grow I would not recommend hydroponics but soil. The soil is much more forgiving then hydro. Good luck.

Thank you for the input. I've changed my growing medium to soil (FoxFarm Ocean Forrest).

Anybody have an idea how loud the GrowBright 4" Tall Boy Inline Fan & Carbon Filter Combo is?

Thanks again for any input!
