Humidity

Hi what humidity should I have for growing auto's??

in flower you want between 40 and 45% humidity. try not to go over 50%. and in veg you can go a little bit higher.

Too low for both veg and flower

Look up the term VPD and cannabis. It will influence your decision about the common advice of 45-55% etc. Your humidity is dependent on your temperature and the plants actually enjoy a higher rh%.
You'll grow good weed either way, but remember VPD for the future

I've added a diffuser to the tent and got it up to 44%.

Reckon I will get away with it?

How did you get on at 44%?

Too high of humidity isn’t an issue if you have sufficient air flow. I use 60-65% RH from seed to harvest. I typically only drop my RH to about 30-35% the last 2 weeks before chop time.

If you are new to growing I wouldn't worry about that too much right now. MJ is pretty hardy and adaptable. As already stated later in flower is the most critical time as far as humidity goes. Then you want to do your best to keep it below 50% to decrease your chance of bud rot.
