Cheers from another MN grower! My current grow won't survive to see itself become legal sadly, but we're close!
The important things are to keep it simple, but also buy equipment you can grow into
- Grow tent: Assuming you're looking to get to 4veg/4flower eventually, here's one to grow into. I'd recommend a 3x3 or 4x4, whatever you can fit. Either will be able to become a veg tent with plenty of room for 4 plants
- Lights: You can get stuck here for sure. My recommendation is to grab a 240w quantum board off aliexpress. I've got 3 of them now in 2 tents, and I've never had an issue. Great for growing anything in those tents and providing more light than the sun
- Ventilation: Carbon filter, good to change every other grow or so. 4" ducting is fine, but at some point you'll wish you had gone 6". Any of the fans and filters you find are good
- Growing medium: Here's the part where it'll vary. What's your gardening experience? I started off with DWC hydro, but that's definitely not a move for everyone. I grew a lot of other plants inside and out before planting my first cannabis seed. There's nothing wrong with grabbing some potting mix and fabric pots, and just going that route; you'll still get great results. It comes down to how much control you want and how much you're able to focus on details.
- Nutrients: Another spot for analysis paralysis. If you're in the cities, it's worth taking a trip to Midwest Hydroponics. I'm guessing you'll hardly be the only one getting set up here, and those guys really know their stuff. There's so much marketing trash to sift through, and in many cases people are just pissing away money feeding the plants more than they can take in. Your choices will range from preparing a soil that has everything the plant will need and you just give it water, to daily feeding and a grow room looking like a mad scientist's lab
- Seeds/clones: I have no idea what our situation will look like for buying seeds in MN, but they're definitely not hard to order online. Your major options will be auto or photo, and you'll find strong opinions for each. I personally grow autos, and run a 24/0 light cycle. Photos usually gain yield and strain options and add complexity. This one will also come down to personal preference.
This site's a great resource, and there are many others out there that are very helpful as well. I've lurked for awhile, but your post got me to actually sign up here. Cheers, good luck, and remember to keep it simple: there are so many variables to tweak and change, but get the process and lifecycle down first
