First Grow - Critical Mass aka The Twins

she looks amazing! your lst is on point have you ever looked into mainlining?

To answer your question: There's a couple of things that you can do: the first is to increase the exhaust and the second is to try to increase both lights on and off temperatures, as temperatures rises the rH will drop drastically. Actually low lights out temperature is the main reason for high humidity during flower lights out, so if you can heat your grow space during both lights on and off it will really help and since you have your lights on temperatures at 19°C (66°F) there's some room for improvement. Good luck

Happy new year my friend! Your grow is looking fantastic and healthy and I wish you best in this next year growing some amazing plants and yielding yourself large amounts of bud. Cheers!

you got skills on LSTing! :)

Yeah buddy looking good thus far. I am also at 4 weeks of Veg and I have 2 Royal 👑 Gorilla’s 🦍, and 1 Gorilla 🦍 Bomb 💣, & 2 Velvet Bud in my garden at the moment that are 28 days into Veg. I just hacked them up starting to do a modified manifold which will extend my Veg by a week or two. My stuff looks 👀drastically different than yours, however, I am a RDWC Hydroponic cultivator so that explains the difference after 28 days of Veg. I post bi weekly videos to my YouTube Channel.
