My room is 7ft high 5 ft long and 2 feet wide. I have my plants lined up right next to each other, only 2. I cut a whole in the wall and placed the fan there pushing fresh air into the room. Is this enough ventilation to supply 2 plants with the proper amount of Co2? I keep my room at 50% humidity and 72-75 degrees F.

I also planted my 2 plants in 3 gallon buckets with drilled holes for drainage. I water once a week and feed with GROW BIG by fox farms. My soil is also fox farms OCEAN FOREST. I spray my plants with carbonated water once or twice a day and my plants remain 6-7 inches tall after a month and dark green leaves which are pointing to the light. :lol:

Can someone help me with any tips to improve my plants? Also, is 6-7 inches tall good after 4 weeks under a 4ft flourescent light?
