ahhhhh okay lol but yah just go to lighting in home depot or lowes and find all the individual sockets theyll just be in little clear bags, normally the lamp cords are right next to there also
and yah it will definatley work throughout the whole grow, youll just have to keep adding as it gets bigger, it just takes lots of rearranging and what not plus you can buy pvc pipe or 2x4s for more sturdy fixtures...
i just added an extra splitter so I have 5 bulbs....3x 42W 2700K, 1x 23w 3000k, 1x 23w 5000k. I've done alot of LST so i dont have to rearrange my lights alot
