The grandaddy black is looking happy. Will be switching them to flower in a week or less. I gave them a flush and fresh nutrients. The humic acid really makes a huge difference in the uptake of nutrients. I am at about half dose on nutrients compared to what I would have to feed without it. Winter is approaching and bringing the low humidity with it. All of the humidifiers I have tried either dont work or I have to constantly refill the tank. So I decided to use my redneck engineering skills to throw this humidifier together. It holds 4 gallons of water and she pumps like a freight train. I have dubbed her the Steam Queen. I got 2 cool mist foggers that put out about 400ml per hour each and used some things I had around to make them a little float. Added an old computer fan to force the mist out through a 2 inch pipe. She won't win any beauty contests but she pumps out plenty of cool moist air. I also upgraded my exhaust to a variable speed for more added environmental control. Just going to do a little more training over the next week then try to make some buds.
