<span class="link_user">@ChubbyBudBros</span>, the first 3 weeks It may have grown about half an inch in my case last year.. I posted about my RQS northern lights outdoor grow if you want to compare it to how yours was growing… I actually planted another northern lights auto in my hydro system a couple days ago so it can get massive before I throw it outside with no help lmao anyways they have stayed the same size this whole time even in hydro

<span class="link_user">@ChubbyBudBros</span>, look at my RQS northern lights auto grow I did outdoors… was about the same size for 3 or so weeks before new growth started shooting out

<span class="link_user">@MrBulldops</span>, so from my understanding and I may be wrong- the humidity probably rises because temps drop so air is able to retain water better and the humidity is 55 during light ons is because the air is warm and evaporating moisture upwards allowing the vent to suck it up. I believe the night time humidity is harder to control for me and I can with any guarantee say 60%+ at night isnt going to cause mold. With that said early on I struggled to get it below 62% at night also but used lots of fans to make sure I could have adequate air. In my situation I didnt want to use more power or a dehumidifier so I bought these large silica packs from Amazon - I have up to 8 of them (2 for 15 with the sale and reusable) and 2 can drop the humidity by 1-2%. It also means when you turn off your humidifier the moisture wont linger as much. If thats too much another thing you can do is a red brick and heat it in the oven at 220degrees for an hour or so then let it cool for 20 mins and put it in the tent covered with a single towel and it will emanate the heat slowly increasing night time temp allowing humidity to rise slightly and your vent to get more moisture out. Also a lower vpd during lights out is common so I also wouldn&#039;t panic too much if you haven&#039;t seen issues- and your plants look very healthy my friend. Take care.
