I wanted to mention my previous grow using this tent. Its 32"x32"x60". The light is a Mars Hydro 192x3 Reflector Series. I've had it about a year and itd been 100% reliable. And my last grow with this setup gave me 174 grams of Dragon's Blood! Now the biggest plant was only 24" tall, but she gave me 3 ounces ( 84 grams ) ! The light is so big there is only about 6" from each edge of the light to the tent walls! It fill the tent with light, no shadows! I'd like 4 more of these older lights ( not the 5 watt model ) I'd put all 4 in my 4'x4'x6.5' tent!! I'm serious, I think with the right soil or medium, and pot size, I could get 1 gram per watt in that small space. The true wattage of this light is 345 watts.
Point being, all these plants should turn out pretty well as this is the same soil also as I used last grow. And so far, it looks like smooth sailing.
and yes, I'm excited about this grow! Been 40 years since I've tasted Central/South American weed!
