Well, I was going to build a watering table but decided to turn it into a grow room instead. I took my main base for a watering table and used some PVC pipes to keep it light so I can take it outside and switch from lights to sunlight if I wanted to try something different. I have two 600-watt HPS lights that I mounted but can use four 200-watt Leds as well if I need to. My thought process is That as of right now I have 10 purple haze plants and two California dreams as well and they are in two closets and are getting cramp inside. The weather here in the mountains of New Mexico at night is between 27- 47 degrees while the days are hitting around 67-73 and I am worried about putting them in my garage, So I am building a greenhouse now. My plan is to run the HPS lights during the day for 18 hours and then when they shut down have my heater on a timer to keep it Fairley warm enough so not to shock my plants until the lights turn back on. Here are some pictures of what I have done so far it is not finished yet. If anyone has dealt with cold weather and has a solution, I would love to hear it. My timing was off when I started my grow but maybe this will let me grow year-round. Here are a couple of pictures of my last grow as well.
