help advice on gro op please

Hi,
I am new to growing and attached a picture with my setup hoping for some suggestions and help with a few questions i had. I have been reading a lot on this site and was concerned with CO2 and fans. Do i need CO2 while my plants are still small and vegging and also should i position a fan in any way? I have a window in the room im growing behind the broken TV if you can see that. I have seen a few easy CO2 set ups and was just thinking of making one of those and setting it inbetween my 5 plants. Im running at 600w too. Any suggestions for improvement from what you can see is greatly appreciated. Thanks!

...Also was wondering if i could mix my AzaMax in with my nutrients and water during feeding. If anyone knows...

No you do not need CO2 just fresh air. Will CO2 promote faster growth? Yes it will but it is not NEEDED. All you need fan wise at this point is something to similate a small breeze. You just need to exchange the air in the room every 15 minutes or so IF POSSIBLE. If not just open a window from time to time and make sure your temp doesnt get over 80 degrees on top of those plants. I see your light isnt air cooled so you may want to invest in a small inline fan and some ducting to cool the light. But all in all it should work.

thanks bro you really helped me.

No problem brotha

New pic of inside of the plastic grow room from ceiling to floor.


so i have moved my gro op into the corner near the window wrapped in some nice white plastic. It is near a window and i saw someone posted about a carbon filter https://www.rollitup.org/indoor-growing/7074-easy-build-diy-carbon-filter.html
would it be beneficial to make one of these going from the window into the plastic room? also i bought a nice small little fan to throw inside too.
Thanks for the help anyone...



also, i was considering ventilation. i was reading around and saw there should be a small hole at top for air to come out of with fan up there pointing outward and a larger hole towards the bottom for air to come in. Would it work the same if i cut a door, which i did, and it is dangling from the plastic, not flush but close enough...would that work for my intake, the new air coming in. Hope someone can help me, thanks again.

right now fan is in the bottom blowing up towards my light lighty. should i run it at night? i was considering leaving that fan there and getting another to use at the top for ventilation but im not sure what to do.
