I just finished putting together my first grow box. Its not huge by any stretch of the imagination. What i have used so far is an 18 galleon tote with 12 net pots using Hydroton as the grow medium. I am using 3 5500k 18" T8's and 4 23W 2700k both are adjustable depending on how large the plants get. I plan on putting 6 clones in. The size of the box is roughly 26"W x 20" L x 68" H all covered in a reflective material. Now that I have given at least a simple description of what I am using, my question is can I grow 6 plants without having to worry about over crowding and from everything else that I have read you can never have to many lights. I am worried that I dont have enough lighting or that I am using the wrong spectrum for veg. I know that when I am ready to flower I will need to change at least the 3 T8's. I'm just curious if I have enough or should I get more. I am hopefully attaching a couple of pics but I am not sure if its going to work. Sorry if I am bringing up an old thread but I havent really found what I was looking for. Thanks for all the advice in advance.
