I just got done building a nice size box to put some plants in. the floor space is about 4 1/2 feet by 2 1/2 feet. I got about 5 foot of hight about 4 probable after I put the light and fan and filter in. what im wandering is how many plants can I get in there without sacrificing my yield. I like the himilian blue diesels and mi5s and onyxs and really just any thing that grows under 2 foot and easyier to take care of. this is my first serious grow and want to get it right the first time. im planning on using a high output t5 system with cfl side lighting the t5 system is 4 foot long and about 2 foot wide so it will cover the floor space really nicely I just need to order the light the fan and filter and seeds and im good to go I got it all wired up with an outlet inside the box and a light switch in there that will allow me to turn off half the receptcal so I can leave my fans on and turn my lights on and off
