Indoor Meef's second attempt. 2x AutoWhite Widow LED grow.

I've noticed something with this grow compared to my last.. The plant on my left side is always smaller than my plant on the right. The only difference is that the intake to my tent is next to the larger plant.
More CO2 in the fresh incoming air perhaps? Regardless your girls are looking great, nice work Meef.

Quite possible, who knows. I debated rotating them daily, but I think I'm just going to watch and see what happens. I can't wait for them to start stretching, that's when the fun seems to happen.

Side note, who else runs an intake? I've read mixed things about it. I run my exhaust fan 24/7 and have my intake just being passive air.

Same here. Doesn't seem to be needed to me, with the fan running 24/7 and pulling fresh air in all the time.

I run exhaust all the time with just passive intake, but I have two fans inside the tent just to circulate and mix the inside air and keep everything equal in the tent.
 
Alright, so I have a question about my water situation. I bubble my water a minimum of 24+ hours before I use it. At the top of my bubbling bucket, I get this deposit. Is this signs of hard water? Is this bad for my plants? It's honestly really annoying, because my humidifier tent and lights get covered in it. I'm constantly wiping stuff down.

Looks like hard water scale to me, I am fairly certain you wont get fluoride deposits from evaporation pretty sure RO is one of the few ways to get rid of that nasty stuff. If anyone knows different however I'm all ears. If you want to know if your water is fluoridated you can call your local water authority or search your location on the google there should be recent water quality test result available for anyone to see.
 
Honestly, I have no idea. I just moved down to the city right when I started my last grow. I'm not sure how I would check.
Google what county or city you live in and water fluoridation and see if yes or no. If yes I'd recommend an RO filter and to do a little research:
