The amount of light greatly affects the total dry weight outcome. The more lumens you can cram into that space the more beneficial it is for the plants. With that many plants, I wouldn't go any smaller on wattage. Also, that seems like a huge undertaking for a first time grower. Are you growing soil or hydro. If hydro, you will need to add Co2, lots of air flow and steady temps between 73 and 83, any higher or lower and you'll notice stunted growth. So exhausting the heat is A HUGE key factor. Either way you go you'll also have to take precautions when it comes to plant issues such as: bugs, mildew, mold and various other things that you WILL encounter. You may want help from someone with experience, or cut the grow down to a more manageable number (6-10)- for a "First Timer."
