Thanks for the replies, folks.
That`s a few to research ! I assume that lighting/heating is dependent on species ?
I`m still in the dark about ventilation, in that I`m not sure how many vents I should have & their size. Should I put them in the top, back or sides ? I`m hoping you`d suggest one of the first two as the sides are against the walls of a tight alcove, with hardly 1/4" gap either side !!
Again, many thanks in advance for your answers.
