High humidity

Hi guys currently growing in a 8ft x 8.5ft space, i have 10 plants (6 in coco, 4 in dwc)
I am 3 weeks into flower, plants are extremely healthy and strong

1 gavita pro line 1000w hps
1 600w hps
2 osculating fans
1 x 10inch extraction fan
1 x 6 inch extraction fan
Plants are big and bushy, have defoliated to help air flow and try to reduce humidity

Temps on are 26/27c (humidity 55-62%)

Temps off are currently 17c and can fall down to 14c (humidity in the %80s)



Have just bought a de-humidifier only a small 1 as it's all i can afford right now, was wondering if i put a heater in the room to bring up the temps when lights are off will this bring the humidity down much? Ideally want it 50s and under but will settle for 60s


Any other ideas??

Any help is truley appreciated

Dehumidifiers don't work very well when the air is cool. Plus just warming the air will drop the RH%. So warm those lights out temps up.

Using this chart you can see how temperature and humidity are intertwined. The absolute humidity # is the white area. See what that number does when you change the temp. So for example, 27C and 50% RH = 11.34, now we look at the 17C row and find a close value and it's in the 90 - 95% column.

Use an electric oil filled heater, they won't mess with the dark cycle and they don't add humidity like a gas/propane heater.
