Unverified植物补光选红蓝比例5:1至9:1（红光660nm+蓝光450nm）促进开花结果，纯叶菜苗期可用红蓝3:1增强蓝光壮苗87% similarUnverified开花结果类（草莓、辣椒、番茄）需要更高比例红光（660nm）促进开花坐果，纯营养生长的观叶植物则蓝光比例可适当提高防徒长83% similarUnverified耐阴与叶色鲜艳往往矛盾：花叶品种（花叶绿萝、彩叶芋、变叶木）在弱光下会退化返绿、斑纹消失，想保持鲜艳斑纹需明亮散射光，纯观叶深绿品种才真正耐阴71% similarUnverified叶片越翠绿饱满通常光照养护越好但耐阴性反而较弱，长期弱光环境应选株形稍紧凑、叶色略深的植株更易适应71% similarUnverified耐阴性与开花能力通常呈反比：越耐阴的观叶植物（一叶兰、绿萝）越难开花，需要开花观赏效果（茉莉、栀子、三角梅）则必须保证充足光照，室内弱光环境不要指望开花植物爆花69% similar
