Last year i had no clue what i was doing and germinated 8 bagseeds and non of them sprouted
Sadly, sense I've done this myself, I know what you're talking about.
Thai Buddha Man gave you just about the most sound advice you could receive. There is a wealth of information available here and you need to learn how to utilize it in case you ever get in a jam and need it right on the spot.
That being said, you'll find a very helpful group of people here and the vibe is comfortable. Let's see if I can give you a little jump-start...
How cold can it get at night without stunting the plants?
Unless a strain has been selected to thrive in lower temps, I wouldn't want my seedlings to be in less than 70f and certainly not less than 60f... To be honest though, I am not the best person to answer that question since my avg winter lows are in the 50f's.
FYI... The JEM line and the Dragon line were primarily grown outside during their development. Wiz can give you some very detailed info regarding these strains and outdoor conditions.
When should i start feeding Nutes?
I start feeding at sex.
What size pots should i grow in for maximum yields?
The bigger the pot, the better chance the plant has for maximum growth. IMO, with auto's, 3-5 gal. is plenty big enough... and you can go smaller with some of the more sophisticated mixes and techniques that can be found on the site.
How often should i check my plants? daily or weekly?
Once a day would be great if it doesn't get you locked up or your yield stolen. Seriously, it depends on the situation and the accessibility you have to the grow area. If people can see you entering and leaving, that is not a good thing. If your grow area is close to you, and it's unlikely you'll be seen entering and leaving, once a week (or twice) would be the ticket, IMO.
BTW, Muddy and I are the mods for the New Growers forum and we're always happy to help, as are all the mods and members. It's a good place to hang out or do a grow log when you're first getting started since there are people assigned specifically to help new growers. Come hang out with us sometime.
