If you mean what retail outlets like Home Depot or Lowes sell these type of high output fixtures? They aren't available there. Other than fish shops or Hydroponics stores (for a high premium) you're better off ordering online. I posted this link above to the most inexpensive source I know for T5 HO setups that are ready to hang and plug in right out of the box again its:Do you know who sells them, offhand?
I just use two standard 24" T12 fixtures. At six inches or so they give plenty of light for Drosera, Dionaea, Pinguicula and Sarracenia seedlings. I get a 100-200% factor reading on Barry's Light Calculator. My plants color up better under lights than they do outdoors. Flowering is no problem. I have used a mixture of warm and cool white tubes but all cool white works just a well.
The dual; 55 watt power compact systems I am running do run hot. Tank is normal in excess of 90 F daily. But for petiolaris complex plants that seems to be just fine. Initially I had issues with plants not being as red as I would like needed to mix the bulbs up a bit. Almost thinking that the addition of one 10,000 K bulb added more blue range and perhaps more in UV spectra. So far again guessing that the red colors are related to the plants making anthocyanins in response to getting sun/UV burnt....
It's four tubes of Phillips (green end caps) F20T12/CW ALTO tubes. 62 CRI/4100K.
Same question: Where and how much? This is all being forwarded to my wife (Christmas).
