Yeah I've read that quality goes up aswell as yield if you take the glass off. Its amazing the difference with the glass off; you can really feel it.
I've decided to go with glass off. 35% w/ 27 degrees seems close to ideal.
Hey there,
I could use some help in deciding what to do - I have an air cooled 600 watt lamp in a tent with some plants going into week 3 flowering.
RH with the glass on was about 70% at 68F/20C which is almost ideal VPD. Its gotten cold here now and will be getting colder - temp here...
