I'm in! Nice build going on. I love it when a skilled trades person gets into growing. The grow rooms are so well done. I'd love to be able to build a room like that. You've made the right choice going with DBHBB for sure. I do HVAC for a living so if you need help there, I'm here. Only observation I can make right now is on your comment about using a portable AC. It looks like your room is going to be sealed? Sealed would be the way to go but until you can afford a mini split you'll have to have a way to bring in air when you run the portable. Those exhaust room air to the outside so you need to bring air to avoid exhausting all the air out of your room. I'm guessing you know this but just wanted to point it out just in case. Welcome to the high brix gang and here's to your little buddy getting better...., what strains will you be starting out with?
