Hi. I have been growing for a few years now without a regulated environment. I felt it was time to upgraded my setup with heat, hum and a better light to try push the quality of my grow. I'm about to veg a new grow and wanted to hear thoughts on my current set-up and see if anything could be improved.
4x4 grow tent
6" can max fan
sf4000 light
Humidifier
Various osculating fans
I live in a moderate climate and generally need to add humidity and heat to the garage grow to keep stable temps 80F/55RH in veg. I regulate the temps with 2 ink bird controllers. 1 for temp (heater) 1 for humidity (humidifier). This has stabilized my environment a lot, but have some concern with co2 and airflow.
In previous grows my tent ran cool because I was using fan-cooled cheap LEDs. My new SF4000 has been great at stabilizing the tent at around 80F without running the exhaust fan. In previous grows I had also kept the exhaust fan running 24/7. Since heat is less of an issue now, I connected the exhaust fan to the humidity controller to keep things creeping up too high. In doing so, my exhaust fan is running a lot less than it had previously. Instead I was thinking of connecting the fan to an interval timer. Any recommendations on how often I should run the exhaust to increase co2? Heard 15 mins every hr.
The 6" Can fan has a bit too much flow for my 4x4, even on the built in speed-controlled setting :1. I use passive air intake (6" hole at the top of tent and 4" hole which is connected to the heater) which tends to pull the tent in slightly when the fan is running. Adding more intake holes gets complicated with light sealing, so I used roped to help with this. Ideally wish I could speed control this fan even further, but heard that speed controllers are NOT compatible with brushless type motors. Anyone have experience further controlling the speed with this kind of fan? Should I add an intake fan?
Smell hasn't been a huge issue for me in the past so I have avoided adding a carbon filter. Are there reasons why I should?
Thanks for your thoughts/suggestions.
