Hi, First of all, I want to say that I'm a total beginner in marijuana growing. That said, I want to put a homemade grow box in my closet, and that's why I'm here today. Even if I'm a noob in this kind of activity, I've done a lot of researches on the subject, but I still need help before I do anything. So, my closet is relatively small (how suprising) and there's only a 1/3 part of it I want to use for a grow box, and this one is a little more than 4sqft (30" long, 20" large). However, I want 2 plants in this small space because as a first time grower, I want to have a backup if I mess up on a plant. Also, I only have about 4.6 feet of height for this grow box. I can have it taller, but that height is what I'd prefer. For helping you with these numbers, I made a model of it that you'll be able to see at the end of this. Like I said, I'm a complet beginner and I'd appreciate if you could suggest me improvements, ideas, advices, bring things that wouldn't work, details, etc. Every (intelligent) comments is welcome. Before I finish, I have some questions for you guys: Light: I wand to use LED grow light. I saw tons of these, but they all seemed cheap. However, SOL series, Spectrum King (SK250) and Apollo Horticulture 300w LED grow lights looks good. I want to have your opinion on these. Airflow: In the image I linked below, you can see a intake fan, but not a output fan. I want to use 2 200mm PC fan with 110CFM and 700RPM. I don't know if these are overkill for my grow box, but they seemed efficient since they have 110CFM. However, I don't know where I should place these intake/output fans. Any suggestions? That would be much appriciated Thank you and have a good day! Krok' P.S.: By the way, I want to grow White Widow
