Ok so I am one year into growing. I have done pretty well, I know I can do better!! Starting to really try and tweak my environment for optimal conditions. Learning about VPD, temperature vs humidity relativity, ideal temps in flower with high co2 levels, etc. I have completed 4 harvests running a variety of strains from clone genetics I was given from my mentor last year. They are all very good yielding and quality genetics. I have an average DRY yield throughout all 4 grows of .85g per watt. All the strains finish super frosty and the medicine is very potent. So i have been happy with my results but know I can do better. Also, I had one cycle that yielded me less than the other 3 because it was run in the middle of summer and I battled some temp issues. I run seperate veg & flower rooms. The focus of this thread is my flower room.
Here is my current setup:
sealed room 10ft x 15ft - 7 ft ceilings
6000w HPS - 8" cooled Raptor hoods - 2 inline 720cfm fans
25k BTU window unit A/C
70 pint dehu
injected co2 @ 1500ppm lights on
3 - 16" Oscillating wall mount fans just above canopy
lights on temp 78-84 F (high and low, 82 average)
Lights off temp 66-70 F (high and low, 68 average)
Lights on humidity 25-40 % (high and low, 32 average) WAY TOO LOW!!!
Lights off humidity 60-75 % (high and low, 68 average) SLIGHTLY HIGH!!!
So now that i am learned about VPD i can see my humidity is not ideal. I recently purchased a 6 gallon evap humidifier i am running lights on, and then i started running the dehu only at lights off. My humidity levels are better but still not ideal. I am keeping the humidity more consistent for sure, right around 60-65% lights off and 40-45% lights on. Thinking i need another type of dehu?? I also plan to upgrade my AC to a mini split system with dual zones for my veg room and flower room in the next 6 months. I have been reading about ultrasonic humidifiers, foggers, swamp coolers, etc. So before I make any other upgrades/changes I wanted to get some input and/or suggestions on what moves I should make so I'm not spending money twice OR making conditions worse!! Specifically interested in swamp coolers as they seem to lower temp too (???) so maybe I wouldn't have to go with a mini split and just stick with the 25k BTU window AC if i used one of those? I like the idea of mini split because of efficiency and better temp control, reliability. These window AC's could crap out at any time...
Any help is much appreciated!!
