yo all my fellow 150 pals,

what do they call the method that you put klones in a 20 oz soda bottle and just grow the i cola.....??????
If you are only using one 150hps with nothing else in the cab and going dr bud sog I would probably suggest the 18x16 to keep the distance from the bulb to sides of cab to a minimum. This way you should get a little more light intensity at the edges of the cab. Its hard to say though for sure but either one would work well I think because you can easily (and should) rotate your plants around in the cab so each one gets to be in the sweet spot occasionally. An example of what i mean is say you have 5 rows of 3 plants every day take the row from the far right out scoot all the plants over to the right and put the row you took out on the left so you keep the plants moving around the cab. That way every few days different plants will be in the center of the cab under the light where the lumens are more intense. More consistent yield per plant and probably a better yeild overall!
