Definitely get a proper adjustable tent. Making one from pvc was not worth it. Always maintain filtered ventilation from the window and ample room exhaust back out. I recommend adding a PCO air treatment device in the duct before the filter intake to help prevent mold. Another thing is to constantly check VPD and get multiple wireless hygrometers to make sure your humidifier is calibrated right. Lastly don't over trim and include a good fan and silica/strong-stem nutrients (I forgot the silica).
Don't get the flower combination nutrients. It's much easier to just use pH indicator fluid and measure your own 4-0-1 and 0-4-2 NPK nutrients in water with a 1mL syringe. I used half distilled + half filtered tap water for the base bc of hardness and pH but it's up to u. Soil mix is also important. Coco-perlite is a good base but don't do tons of amendments in it and use it throughout like I did.
