Hi I have been very busy the last few years so not been on the site much. But I am building a 30ft long x 13 wide x 9 ft high. room for my biggest opp yet. My lights so far are (I know I need more). 3x1000w hps lights and 5x 600w hps and 4x 400w hps lights. I plan on keeping the 1000w lights up high and drop the rest lower. I am planning on buying 2x 250mm silent ducting fans that will pull air in from under the room and blow it out at the opposites top side of the room. Using both fans to force new air in an just openings with ducting to push the warmer air out the top of the room. I plan on having 3 rows totaling 99 clones 1-3 strains. I plan on veging for 3 weeks before flowering and then transplanting them in 4-5 gallon pots with a peatmoss mix with some added things. Nutes I only use biobizz bloom and grow and fish mix. Would you guys use co2 tanks in a room this size? and how much more would it yeild with the tanks? I plan on buying 4-5 more 400w hps lights to make sure the room has enough light. I will also use 4 normal fans for moving the heated air. Any tips or ideas from Experienced growers only please. Just need some ideas

Will probably go for 6-8 fans. The only reason I have the different size bulbs is each bulb has its own advantage smaller wattage gets closer with less heat for smaller plants. And bigger ligts dont get close but have that high lumes the 1k lights do more than 140000 lumes vs a 400 doing sub 50000 lumes. How much co2?? For the size of the room? And on a scale of 1-10 how much more would any average grow setup yeild with proper co2 dosages. +-. thanks
