Thermostat

[Ozzy420]

mmmm that was interesting, so with the humidity is it good to have a fan running all the time so it dose not get too high, i have my grow running at night as it helps to keep temps down so through the day should i have a fan running to keep the air flow through the chamber to keep the humidity down or could i just leave my lil desk fan running or i just could just set up another computer fan to keep air moveing through the grow area wile in dark time

I dont use the Thermostat to run my fans, I did when I brought it but after loosing half a crop on mould I got wise,

 

I now use it to control the temps and humity of the air conditioner in the same room as my units, the inlet is from the room, and the exhaust is ducted in to the ceiling below a whirlybird.

 

The A/c is not set up for my comfort but instead is making my grows real happy

Yes, even if the ambient temps are warm, you will still get a noticeable drop in temp, and thus noticeable increase in humidity, (as both are related) after the lights go out. You must have some ventilation, and that means air flowing in and out of the grow, to get rid of the moisture left in the air after the lamps have been turned off. Otherwise, as WP has said, mould will be the result. You MUST vent 24 hours a day. Either a main fan or a secondary one which can still pull the whole rooms air out in under 5 mins.

if you are electrically minded, you can get a microprocessor controlled thermostat at oatley electronics (disposals shop in aus) for $15

Hey Luke - George Lucas' screenwriting is laboured and his narrative meanderings are often to the detriment of the film as a whole. ::
