Metal helide for flowering

Can I use my MH lamps successfully from start to finish? Will the crop be worth the smoke? Why is the HPS lamp better?
可不可以從頭到尾都用複金屬燈(MH)
抽起來會比較差嗎
高壓鈉燈(HPS)為什麼比較好##CONTINUE##

Metal halide (MH) lamps can be used for flowering, but there are two problems that they have when compared with high-pressure sodium (HPS) lamps. The first is that they don't emit as much total light. HPS lamps emit more than 20% more light, so MH lamps are not as intense when covering the same area. Second, they do not emit as much orange and red light as HPS lamps. These spectrums seem to promote flowering.
複金屬燈可以用在花期
但是和高壓鈉燈比起來它們有兩個問題
一是發出的光比較少, 高壓鈉燈的光量比複金屬燈多20%
二是發出的橘光和紅光沒有高壓鈉燈多
這兩種光譜似乎是花期所需

However, MH lamps do have several advantages over HPS. First, they are less expensive to purchase. Second, the light does not have a really weird telltale spectrum. It looks white, not pink or amber. Third, the lamps emit more UVB light than HPS lamps, although still in very small amounts. The amount of UVB light plants receive is directly related to the quality of the buds. The more UVB, the higher the quality. Buds grown under MH light will not be as big as buds grown using HPS lighting. However their quality will be as good or better.
然而複金屬燈和高壓鈉燈比起來的確有幾個優點
首先, 它們買起來比較便宜
其二, 它的光看起來不奇怪, 它的光是白色的, 不是粉紅色也不是琥珀色的
第三, MH發出較多的UVB紫外線, 雖然只多一點點
大麻吸收的UVB量直接關係到花的品質, 紫外線越多花的品質越好
花期照MH的花不會像照HPS的花那麼大
但是品質卻是一樣甚至更好一點
