Unverified判断实际光强要看PPFD（光合光子通量密度）而非瓦数，多肉/观叶维持需PPFD≥100-200 μmol/m²/s，育苗需≥200-400，果菜需≥400-600，照射距离越远PPFD衰减越快75% similarUnverified不要迷信'植物性=低嘌呤'而大量食用豆芽、芦笋、紫菜、干豆类，这些植物嘌呤中等偏高（芦笋约150mg、紫菜约270mg/100g），急性期应限制71% similarUnverified叶菜类水培营养液EC值控制在1.2-1.8 mS/cm，果菜类（番茄、黄瓜）需2.0-2.5 mS/cm，观叶绿植0.8-1.2即可，浓度超标会烧根71% similarUnverified叶菜/多肉育苗层间距15-25cm足够，但结果类植物（辣椒、番茄）需层间距≥40cm，购买前确认可调节支架的最大层间距而非仅看层数69% similarUnverified凉拌菜份量按食材种类判断更准确：叶菜类（如凉拌菠菜）焯水后缩水约60%，标称500g实际熟重约200g；根茎类（如凉拌藕片）几乎不缩水，按需选叶菜类要多买66% similar
