So this is my first attempt at a grow journal. It'll kinda be a mix of what I've run in the past and the run I'm on now. So my homemade mylar lined flower cabinet measures 2 ft deep, 5 ft wide, and 4 ft tall. I also have a veg cab that measures 2ft x 2ft x3 ft. Also lined in mylar. The smaller of the two is my veg cabinet. So for lighting. My veg cab I run 6-23 watt cfl bulbs. 4 are 6000k and 2 are 2500k. My flower chamber is lit by a 150 watt hps and a 300 watt eq. Full spectrum led. Lights in the veg run 18/6 and in flower 12/12. Ok ventilation in the little veg chamber is achieved by a 90 mm 12v pc fan I have inline a 4 inch metal flex duct. Outside this chamber I have a homemade activated charcoal coffee can filter. Inside I use a 45mm pc fan suspended for air circulation. In the flower chamber I use a 4inch vortex fan rated at 190 cfm and a can filter I bought off ebay. I also have a small desk fan to move air in this chamber. My Temps get to about 76f in the flower chamber and the same in veg. I also have a co2 production device using citric acid and baking soda which pushes co2 into the flower chamber at about 1 bubble/sec. I know it gets vented but I figure the ingredients are cheap enough I just run it in flower to help production. I should also mention I run a separate cabinet for clones set up in a similar manner as my veg cab but only 2 23 watt cfl and a heat Matt and humidity dome. Venting the same as the veg cab. So here's a couple shots of the veg and flower cabinet. I don't have a photo of the cloning one but will get one soon.
