Set Up TentHow should I set up my carbon filter, exhaust fan & air ducts? I’m in limited space right now but want to make sure I get good air circulation still. I set it up the wrong way the last time I had it up but it was already up so I just left it. Also, my fans. Where should they go ?Setup. Lighting

4x4 16 Plant Veg Time and TrainingHello guys, I am planning on flowering these 16 ladies in my 4x4, but I am unsure of how long to veg and what training to utilize for maximum yield.
I was thinking 3-4 weeks? Or maybe longer?
Is topping in such a tight space a good idea? If yes then at what time?
Thanks!4y ago

1. Keep growing all 3 to maturity, use LST to manage size
2. Sacrifice one plant for the good of the other 2
3. ???
Thanks!Week 3

Well water PPM/EC looks REALLY high. What to do?I just did a quick test of our well water with a new cheap little meter and found that with our softening system on I hit 267PPM and an EC of 568(!). When I bypass the softening system I end up with 209ppm and and EC of ~450. Am I killin' my own plants?Setup. Other

Week 3 Flower, High RHSo I held off buying a dehu to see if the mini split in the room would be able to keep up. Resounding no lol I've never had RH this high into flower (~70-75% @ ~3w flower). Should have dehu in a 1w. Am I safe to keep going for another week like this or should take action now.Other. General questions
