水草情迷

我個缸24'X14'X18(high)
用T5HO 24w X4種迷矮同其他陽性草夠照嗎？
其實係點分辨枝燈夠唔夠光？？

夠喇，大家都係T5HO，牛有影響、管有影響，好難一概而論，又係睇你預算，種落加埋其他配套，慢慢試都冇壞。

For yr info. My T5HO is germany-made product. Only opening 2 tubes (54Wx2 philips) made the 48-inches tank(250L) bubbled like snowing.

So, I suggest, in the long run, splitting into 2 sets 24Wx2 or 1 set 24Wx4 with 2 electric plugs for 2 timers that make it more flexible to control light intensity. During initial stage, just use 24Wx2. After several months the plants grows well and becomes more stable, it may require much quantity of light. Then use one more set 24wx2.

Agreed. The transformer can be a bottle-neck. I use a BCD 24wx4 (PHILIPS 865; total 96w) T5HO but it only consumes 55w when I use a wattage meter to measure the power. 41w less than nominal rating!
