will yield increase enough to off set the extra energy my minisplit will be using?
No doubt dude.
will yield increase enough to off set the extra energy my minisplit will be using?
I air cool in a sealed room. It allows me to get my lights closer, making up for the 10% loss. The biggest benefit is I direct all the hot air directly to the intake of my AC. So when the AC is running, the hot air is being dealt with immediately.
Yes, it dumps directly into the intake of my ac, it gets dealt with immediately. Otherwise heat just radiates from my hoods down onto the canopy.
You do know you're just shooting yourself in the efficiency foot to the tune of at least 10%, right? You would get noticeably better results by simply removing the glass and raising the hood- and no, doing this would absolutely not result in less lumens on your plant's leaves. Things won't be quite as hot in the room that way, either. You've just demonstrated with your vent blowing into the face of your AC that your cooling system is up to the job of cooling your grow without assistance. The only reason to run sealed and vented hoods in the first place is to dump excess heat; otherwise, it's a complete waste of light and the energy to make it. And that hurts your yield and your wallet- both to buy the excess power being wasted and the AC to cool it, but also in less money from your crop.
I agree glass less equals more useable light which equals higher yields and is better overall. However in my experience and needs I find I like the more consistent controlled temps and management of the heat. Sometimes bulbs blow to, just had my first bulb blowout ever a month or so ago, glad hot glass didn't go everywhere. I find I can get my hoods closer when air cooling which probably makes up for the 10% loss.
No, moving your hood closer is just making up for light you've spent money for and are throwing away- while still spending top dollar to cool it. The spot directly under the sealed hood will be bright, but the spot itself got a lot smaller!
This is intuitively obvious- and you've got some of the best minds on the Farm all telling you the same thing. You came here for advice, take it!
