I would recommend a t5 uvb they are more efficient and are the better option. T8 are better than coil but for a veild I would recommend arcadia since they last longer and the t5 desert 12% uvb. But you would have to buy a t5 fixture to use a t5 bulb. Also if your looking for more plants walmart is a good option they have pothos and hibiscus now and even some have them marked down to 50% off.
