Runtz 13 (Newbie first official run)

First time grower, I’m open to any suggestions and tips. -Nov 19.. humidifier should be in today it’s super dry in my apartment in nyc (it only dropped so low because I had the tent open for over 10 min usually hangs around 30-40 tent closed without humidifier), i should be getting a better light within a week or so. The plant in the back is a practice run bag seed. I wanted to get familiar with how the leaves grow watering just basically get my feet wet before using seeds I spend money on. I will be killing the plant after about a month or so, I don’t want to risk it messing up my “real run” ( if that makes sense lol 🤷‍♂️).. anyways I’m open to suggestions and tips. (Limited space 2x2x4 tent in an apartment). -Nov 21.. both babies sprouted, my 4 in. in-line fan from ac infinity and controller should be in tomorrow and Wednesday my official light for this 2x2 tent should be in also by ac infinity the 130w iongrid t22
