Puffdiddy Posted April 22, 2022 Share Posted April 22, 2022 Hi Growmies I'm having a small panic about keeping my environment bang on and wanted to ask for your tuppeny bits! I've got 8 - 58L pots with healthy plants just at W4 flower - My temps are 27* and 20* and very stable - Im using the GAS enviro controller with the Revolution V2 8” - I’ve tried to drop my humidity to 50% using the GAS but it won’t seem to pull it down below 60% - I’ve checked all my settings and as it gets to 62-63 heater kicks in (dry air blower) and humidity rises… I’m a bit stumped! Could it be my outside tent humidity is just to high ? I’m using passive intake through two vents 400mmx300mm and have two clip fans blowing at them. I have good NAP on tent walls but not daft bowing - fan is set 30% min 70% max - if I go higher than that / worried it’ll suck itself into some sort of black hole implosion.. hope this is making perfect sense to someone !

sweettooth Posted April 22, 2022 Share Posted April 22, 2022 60 to 65% RH is perfect for your current situation. Plants look great. Heaters kicking in as temps are dropping too low and warmer air can hold more humidity. I had to opt for a 50L dehumidifier in the end, only way of getting it down when I need to. How long do you veg in pots that size? Link to comment Share on other sites More sharing options...

desertshaman Posted April 22, 2022 Share Posted April 22, 2022 (edited) Hi @Puffdiddy.. Nice grow man! Plants look good. I've been following vpd charts as well and I reckon the humidifier in veg really helps. I haven't used it in flower because the humidity between the plants is quite high especially without defoliation. And for me it's more important to increase air flow than slow down the extraction to increase humidity. I had bud root last time as I had too many plants and it was heart breaking! Where are you measuring humidity btw/where's the sensor placed? Also I'm a bit confused ...I thought as hot air carries more water Rh will drop as temp rises. If I'm right and as yours goes up I bet the rh in the lung room is quite high. Have you tried tube heaters instead of blowers btw? Your plants look great .. And I bet you're looking forward to a nice harvest soon! There's nothing like your own home grown... Ps I would add more fans for airflow in the tent if you've only got 2..
