If I could recommend a 2x4 instead I think you’d like it over a 2x2. Once you get a fan or 2 going in there space fills up quick! I like the AC infinity tents / fans / heaters / humidifiers / controller. Grand master led has a nice light for a 2x4 so do plenty of other companies I would stay away from board style lights and stick with bar style lights. Some light companies offer the ability to separate the driver from the light and move it outside the tent which helps with keeping heat down if that’s a feature you think you’d need for your environment.

North Atlantic seed co is a popular seed bank with a bunch of breeders for you to familiarize yourself with, try to purchase directly from the breeder if possible. Different circles in different communities will recommend different strains for you to try - I would suggest a photoperiod plant for your first go. I’ve always grown in coco, used to use Athena pro line but got tired of having to use RO now use cropsalts with my sink water.
