Temperature and Humidity Problem - Growroom Designs & Equipment - International Cannagraphic Magazine Forums

Alpagumay · 11-29-2017, 09:28 PM

Guys I have small cupboard that I use for growing with cfl's. For now I use 2x23 V cfl for gemination and my Temp is 26C my humidity 50%. My problem is when i put 2 more cfl to increase the light the temperature becomes higher than 30C. To decrease the temperature I use fan but this time my humidity lowers to 20%. What can I do to solve this?

And I also use humidifier all the time to keep my humidity around 50%. Otherwise it becomes 25%

A couple ideas

1. put an exhaust fan up high on a timer

2. Get a real tent. Sounds like there's hardly any volume of air in your cabinet. Plants need to breathe

I have already 1 exhaust fan and also 1 fan for ventilation on inside both are 5v currently. When I change my exhaust fan or other fan with 12v the humidry lowers again ://

maybe seal around the lights with some wood and glass and vent the lights separately.

you should be able to maintain ambient temps in the cabinet with good air exchange.

the room that the cabinet is in: can you raise humidity in this room with either an ultrasonic fogger or some other type of humidifier.

you cant raise the humidity in the cabinet itself because you are exhausting the air so quickly, so you have to humidify the "lung" room.

If you use a humidifier you should notice a temperature drop, especially if you aim for 65-75 percent RH you should drop around 3-4 degrees. This in turn could allow you to slow down your exhausting and keep a more consistent humidity. Instead of cfls you could also try using screw in led lamps to bring the temperatures slightly lower, they cost a bit, where I live the government gave out energy grants and we were able to buy them for around 50 cents a bulb, needless to say best 60 bucks I have spent in awhile.

I think im going to use glass for cfls. Does it help much? Any suggestion for this method?

Separating your lights exhaust from your grow space will prove hugely beneficial.

Yes but does glass block the growlight rate ?

yes glass blocks a small amount of light and a good deal of UV.

need more volume for air exchange. micro growing comes with all the problems of a larger grow but is harder to manage due to scale of the environmental tools Things that work in tents should work in smaller grows so you need a humidistat and a thermostat to control the extraction of air when the set points are crossed.
