It's all in the math GTC21. light intensity diminishes exponentially fast! A 250w HPS is only good light for about 14" away from the bulb. Yes the plant will grow some buds even 24" away from the bulb but they will not be the same quality as the buds grown directly under the light. So that's why they got the rep they do have. If you grow plants over 24" tall then the yield will diminish exponentially.
