I have a question?
My humidity is still around 50%.
Should I get a dehumidifier? I can get oner very easy.
Humidity is a concern once the buds start really packing on because of bud rot/mold. Looking around id say 50% is good. That is what I ran the whole time with no problems I think the Jorge video said high as he would go is 60% but let see what everyone else thinks

I have a question?
My humidity is still around 50%.
Should I get a dehumidifier? I can get oner very easy.
I flower my ladies at 50% humidity and do not have any powdery mildew or bud rot which I attribute to my Oscillating fans and exhaust/inlet fans. I have the ability to run a lower RH but I choose not to for several reasons. The first is a heat concern, especially during the summer months. My dehumidfier exhausts heat into the room. It would take a major modification to get the exhaust out and not to mention the added filter for odor. This is a constraint more than a choice, I know, but I can run cool enough at 40% if I wish.
The second reason I don't go below 50% Rh is that plants transpire much more at lower humidity levels. For hydro that means bigger swings in ppm with smaller resevoirs and having to add back more water more frequently. Even when I am running at 40 gallons in the res. I notice larger swings in ppm with lower Rh.
I would rather the plant use the water in it's cells and cell walls than stress it constantly by making it work harder to cool itself. There are other ways to stress a plant for more trich production that don't stunt growth as well. One that is beneficial is simply "light intensity". Getting your lights closer to the tops increases the trich production in response to the increased intensity. Just as long as the light is properly vented, heat stress which IS detrimental to growth is avoided. I like to keep my lights about 8 to 10 inches away for optimum coverage and intensity. nearing the end of the flowering phase, the last couple of weeks, I lower the lights every other day to 4 inches above the tops.
I say experiment. Find what works in the environment you have and watch the ladies responses. That is the best way to fine tune your garden environment. If you can add a dehumidifier without negative consequences, I would do it. I am going to be adding A/C to my room which may negate the need for my dehumidifier and eliminate the heat it produced. However, I suspect I will still maintain the Rh at or near the 50% range even if I can lower it without negative effects on the environment.
I appologize for the lengthy reply, I am waiting to see if I am working today or not and your thread had the misfortune of catching me at such a time.
Almost forgot, your ladies are looking fine bro! Keep doin what you are doin!
Nice info DrDan, +reps. I am going to be running a 150 watt HPS for flowering when I get back home. I have been looking into LEDs though as a possible replacement later down the line. I have seen some LED systems outperform HPS systems and then I have seen some LED systems unable to sustain plant life. (cheap chinese built ones mainly)
Cant wait!
That looks like it is just the ticket for the space you are growing in. Nice find Acer!
Thanks ScarDcaT and Dr Dan!!
I will get this product and let you all know how it works. They are mainly used for gun cabinets and boats...who knows...if it reduces humidity without heat!! Its worth a try!!
Thanks Green!!High Acer! Looks like you are getting good advise.
