Are u a troll?I recommend the mars hydro COB to you, the coverage is 2.5'x2.5', it's must suit for you, and COB is popular led grow light series, many growers like COB, I didn't agree DIY, it is not safe, I have bought the mars hydro from Joy, she is very kind and help me a lot, you can contact her to get more information and professional answer, her email is [email protected] . maybe she can give you discount too:)
