looking good, how many lights you going for? if you dont mind me making a suggestion, i always used 400's and 1000's...the 400s werent enough and the 1000's were too much, they advertise 1k lights to cover 7x7 areas, for me thats not enough to produce dence monster colas, i attempted to use a 1k in a 4x6 are and the outer edges werent satisfactory, and the plants directly under the lamp(i like em close to the air cooled hoods) always get light bleaching, too many lumens in one place and also the 1k lights are harder to cool, i found 600's to be perfect, especially digital 600's, with these they run so cool you can keep them inside your space, i like to run my 600's in a 3x4 space, so if that was my space i would use 4 x 600watters, but thats just me, good luck bro and lovely carpentry skills
