9 plants on an Easyfeed watering system
5 x Dimlux on a Maxi controller
1 x 8" outake and 1 x 6" outake through aircooled lights, one 8" intake fan, all controller by a Control Freak box
2 x portrable 20ltr dehumidifiers on inkbird controller
1 x oil filled radiator for night time on inkbird controller
4 x small air moving fans
When it's hot the lights are regularly dimmed by the maxi contoller to keep the temps below 30deg, often by as much as 7
70%. So during the last week of flowers I was struggling to get the humidity down to 50%, mostly it was up around 60%. I borrowed an old portable aircon unit from a mate and it made a massive difference, it immediately got the humidity down to below 50% and cooled the room. However I did run it through the 6" outake fan and inline filter. I presume a portable system has to go through a filter and possibly and extraction fan?
So my question is if I go out and buy a an aircon unit is just a £500 portable one enough and if so any recommendations, or should I get a more permanent wall mounted one with an external fan?
I have though about the Opticlimate system but the £3.5k investment is a bit much atm.
