Outdoor enclosure :)

[Improvise]

Ok i have found a solution for the outdoor security!

So out doors i am using a 10'x6' greenhouse, linked to a purpose built indoor insulated shed of 2.4m x 1.2m and 0.8m high. Firstly would this height be enough clearance for heating and lighting in this area?

This will then have a clear cat flap to go outside to their area which is going to be 13' x 7.5' as this is the biggest dog run i could find on the net at a good price. This will sit on sleepers for added outdoor security.

Now in the greenhouse i was going to use a T5 46" tube and will need some heating also, any idea's wether to go for ceramic or bulbs? Same for the indoor area, only this time i was again going to use the T5 tube but use tubular heaters, would this be ok? Any help on what timers/thermostats to buy would be great also. Would rather buy everything at once and get it right first time!

I need to get gowing on this as i pick the tortoises up in Febuary! Any help on equipment would be appreciated They are Hermann's btw
