Definitely go photoperiod. And save your money ordering from Grower’s Choice. Order from Neptune’s Seedbank or Well Grown Seeds. They have good genetics that won’t waste your time or money. I prefer Mass Medical Strains as their genetics are some of my favorite varieties and they do great work during the stress testing while making new strains. Plus, they always smell Dank!!
Best of luck to you. Anything sativa leaning you want to flower sooner than the second fan. Plus, it lessens Veg time a bit. I discovered the hard way that autos are hit or miss. I’ll be running purely photos from this point on in my Grobo. I’ll save autos for the tents.
Next Grobo grow will be Alien OG from 207 genetics, of course, they did not breed the strain. Merely made seeds from another cut. Regardless, I’ve had good luck with 207 genetics thus far.
