Dont have it on your timer system, or it will come on at lights out, and bad. Thanks! Quote Link to comment Share on other sites More sharing options...

zolrooker Posted June 26, 2020 Author Share Posted June 26, 2020 Question regarding ventilation.. I have read that the air needs to be completely exchanged at least every few minutes. Ive got a grow area that is 0.8m3 Extractor fans that run at 90m3/h So theoretically, if i keep the fans running 24/7 , it will do over 1 and a half change per minute, if im not mistaken.. Can i put my extractor fans on a timer, to only run every other minute? i.e. run for a minute, then rest for a minute and repeat.. This would mean approximately 3 air changes every 4 minutes..

zolrooker Posted June 26, 2020 Author Share Posted June 26, 2020 Better yet, if I run extraction fans for 1 minute and then pause both inflow and outflow for 2 minutes (whilst still running oscillating fan obviously) that would still be 3 air changes every 6 minutes. Would it be OK to let it stand like that for 2 minutes with the same air circulating? Or would it result in any detrimental effects? Quote Link to comment Share on other sites More sharing options...

If your room has passive air vents, or you could make them, then run one extraction fan only, and let the room suck in air, then you wouldn't need them both going. Also my opinion and what I'm currently doing myself. You'll easy tell if your temps get to high or you cant get the humidity right, then you can add the second fan, pulling or pushing air, if needed. 1 Quote Link to comment Share on other sites More sharing options...

zolrooker Posted June 27, 2020 Author Share Posted June 27, 2020 (edited) So it begins. Removed all the shelves and cut the top shelf to 150 strips on either side. Still alot of work to do Edited June 27, 2020 by zolrooker 1 Quote Link to comment Share on other sites More sharing options...

Can the fan oscillate fully, otherwise you could always put the fan outside and leave the door open, till you need to go stealth and then close it inside. Maybe a smaller fan x2, your space got smaller too. Quote Link to comment Share on other sites More sharing options...

You can also lift the fabric pots off the floor and then get more upwards flow through the plants. You have passive air ports at the bottom, or are those the slots you made, or you pumping air in with the other inlet fan?

If you do not disperse the fresh air a simple flow will occur from entrance to exit and your plants will not get the needed CO2 to grow. This information by @Prom is good stuff, You want that fan oscillating, or another smaller fan somewhere in the oscillating and kicking air out of regular patterns. You will get WPM is your flow isn't good or changing directions and refreshed constantly (last part if you not doing co2 and closed room, and controlling the humidity precisely). Your one fan, not oscillating, is risking it in my opinion. 1 Quote Link to comment Share on other sites More sharing options...

Totemic Posted June 29, 2020 Share Posted June 29, 2020 You are going to want all that electricity on the floor lifted. I keep all my electricity connections outside my space.

Definitely, all electric good off the floor, even outside the grow room is better for humidity. 18 minutes ago, zolrooker said: Cool, probably gonna replace the fan though anyway too, with something slimmer .. so i can get more space.

The_StonedTrooper Posted June 29, 2020 Share Posted June 29, 2020 Once you get bitten, you'll want to go bigger and improve as you learn or your process changes. You are fine with air in, air around, and air out. So no external fans needed. I can see you doing a few grows as such, then expanding later 1 Quote Link to comment Share on other sites More sharing options...

zolrooker Posted June 30, 2020 Author Share Posted June 30, 2020 (edited) Going to start germinating tonight. Jiffy pellet method. Thinking of germinating behind my fish tank which has a high humidity level (will check min and max readings tonight), while i finish up my grow cabinet. Should i cover the pellets after i add the seeds? Should i watch temperature in that area? Any other advice you can give me ? I germinated some seeds in that area a month or 2 back with a 100% success rate (paper towel method), before temperatures were as low as they are now.
