Hey there!! I can personally recommend Sun Hut. they make some great tents, reasonable price great quality I love mine!! Also can recommend Home box I have both of them and they are great not to sure on the price of Home box it got a deal on it because I bought it from a friend and it had no frame but the tent material is top notch I think it's better than Gorilla's quality . Gorilla is another top brand name tent but can be pricey I have not used one personally myself but have seen their quality and it is good. There is so many Tent companies out there now and if you look around you will notice that a lot of them look to be made by the same manufacturer so definitely do some searching as you will most likely be able to find the same tent for many different prices. As for carbon filters Active air is a great company for them they have great prices and good quality.Another couple reasonable priced and good quality brands of filter is Phat and Atmosphere ProFilter. all three of those companies are fairly close in price but the Profilter from Atmosphere has ones that are in the higher of the price range. Hope this can help you out! Happy Growing!!😎👊
