I desided to go full CGE. Got ride of the intake fan and added Co2 tanks hooked up to my fans. It's on a timer 15 on 15 off during lights on. Keeping ppm around 900. Needed to add a dehumidifier sence humidity got above 75% at times.The heat is pulled out of the room with a 4" booster fan and exits the room thru a fillter sence it is taking kushy air from the room. Lights are still cooled with closed loop. But exoust is now set to turn on when temps it above 85.
Flower room is in week 3 and about 18-24 inch tall just finished trimming leaves to let light in. This will be the last time I tuch them till harvest. Got res ppm under check so no more burn. Veg room is staying at 75 deg. And 70% RH.
Think I took clones to erly so had a bitch of a time keeping them. But in the end I only lost 1. First 1 in over a year. Good thing I take 24 for the 17 I wanted. Setting up a mother room that will hold 2 mothers in DWC using T5 lighting. And natural air so around 80 degrees and 30% RH with 300 ppm of Co2. This is in my house.
Not looking to get the full 1g per watt sence I made some big mistakes in start of this grow but damn sure gonna try next. Next week clones are going into my perveg system for a few weeks while I try and finish my 1200w veg room. If not I added a T5 4'x6 bulb light that will at least let them veg to a decent size befor placing under 2400w MH for a week then switch to HPS and flower.
Well that's all I got for now. Wish me luck and happy growing. I'll try and post weekly photos but got called out of town for work so maybe every 2 weeks.
