Guest ickiwoo Posted February 9, 2013 Share Posted February 9, 2013 My AC reflector is my best ever buy regards environment, I was always fighting extreme temps and the plants always showed their disquiet, now my temps never move more than half a degree and the plants look a lot happier for it. What about the pipe work mr bond i take it you have a condenser external then the unit in your space. A friend has exactly this but he groom is a shed and the condenser is disguised near a bbq.As youve stated its perfect. Link to comment Share on other sites More sharing options...

Budelaire Posted February 13, 2013 Share Posted February 13, 2013 (edited) Rootball temps dont want to be getting below 18 degrees and that is at floor level seeing as that is where its the coolest as below this phosphorous in the plant starts to slow and not above 25 degrees as this just encourages pathogens to breed Ideally ambient temps want to be 76-78 degrees. I dont measure temps directly under the light Cannabis loves around 70% humidity all the way through its life. Its only us that try to reduce it to lessen the chance of budrot late in flower especially. This is normally only a problem at lights out Air should be exchanged at least 20 times per hour to replenish co2 and running 24/7 If using passive intakes you should aim for 5 x the size of extract if using the fan at full speed If pushed for one to keep right it would be rootball temps. Hope that helps Owd Regards this Owd, I've just got a fan/environment controller with probe. Is it a good idea to bury the probe and set it at 20ºc or simply place it under canopy at pot level and set at 25ºc? Thanks Edited February 13, 2013 by Budelaire 1 Link to comment Share on other sites More sharing options...
Budelaire Posted February 14, 2013 Share Posted February 14, 2013 Anyone got any thoughts on this? Link to comment Share on other sites More sharing options...
Guest ickiwoo Posted February 14, 2013 Share Posted February 14, 2013 I stick the outside temp lead in the medium B.Not the one of the controller. I monitor the medium with this and its usually 2 degrees lower than ambient.Im only up there feeding times though.It s not dropped below 20 c on recent grows since ive up graded my heating.Underfloor and tubes. I would put probe at canopy mate. Link to comment Share on other sites More sharing options...

Budelaire Posted February 14, 2013 Share Posted February 14, 2013 (edited) I'm going to get a "Root It! soil probe/thermo" and use that to control the heated underblankets i run in flower... handles up to 500w. You can get ones that handle 3.5kw but they are 3x price. It's currently at the bottom of the canopy, just hung in one of the bushes.

Budelaire Posted February 14, 2013 Share Posted February 14, 2013 Well i run the controller at 25ºC for air, and then this Root It! will control the heating in line with media temps... which i will set at 20ºC. Link to comment Share on other sites More sharing options...
