Please provide your tank size for judge.
Different tank depth, use different type of lighting.

好多師兄老手都話種草用 T8 或者 PL 都比 T5HO 好，我現在用緊 T5HO ，會諗住遲啲試吓 T8。
有機會既話就做個測試報告俾大家啦 :p

可以參考一下︰水草栽培新世界︰T5 或 T8？

Thanks all your reply.
My Tank size is 48" (W)X 17" (H) , Curretnly I plant some red Butterfly, drawf Peral grass. And use T5HO(54W) x4. The plant can grow but not in good shape, some one told me T5HO is not suitable for grass planting so consider to change .

T5HO should be good for your tank, but do you know the colour temperature of your T5HO?
If the colour temperature is 6500K, it ok, otherwise, your
drawf Peral grass will not grow well.
One more factor is supply of CO2.

I use Philips T5HO 6500K. CO2 is one bubble per second.

How long is your tank setup?
One week, two weeks?

should be CO2 not enough...
The bubble meter is only for reference...
My 16" Tank even much more bubbles~~

I prefer use as much as possible ^^ Until the fishs going to the water surface for breath, then it must reduce the volume of CO2.

Light / CO2 / Nutrient <-- Lack of either of them will limited the growth of plants.

師兄，睇完條Link好似佢既 conclusion 係從能源效益角度看
T5>T5HO>T8....

只係同樣24"管 T5HO 火數Watt 高 D

T8 的光譜是較接近自然光，但穿透力較弱。 PL 穿透較較 T8 好，光譜亦不錯，但呎吋和上較難符合水箱的使用，管的選擇也較小，真係要 fit 好多時都要 DIY，例如Edward2004 的 48" 缸便需用 4x55W或 6x55W PL，或 4x55W PL (中前) 配 2x54W T5HO (後)，但市場上 4x55W的燈具也只見過一次，仲要是跟藍 LED moon light 的咸水用燈具。

T5HO 穿透力是三者中最強，管就大部草友用 Philips 865 T5HO. 種草無問題，演色比 Philips daylight T8 較白，但光譜似乎無 T8 和 PL 咁完整，所以魚友多 prefer T8 或 PL, 但我最近的 84" 草缸便是用 8x39W T5HO, 效果我覺得滿意，也不覺得紅草唔夠紅！
