Was it you that PM'ed me? If so I've replied, if not ignore that and I'll explain the same here.
I agree with the above about not using crickets. Personally I think they suck, far too difficult to work with. As said locusts are great and dubia roaches too.
Anyway on to the live plants, I agree there can be issues but not if you know what you are doing and research a lot. In my vivarium I have two types of live plants. I have the tillandsia (also known as airplants), these are amazing and I would 1000000% recommend these. They don't grow in soil so dont need to be planted, you simply mount them somewhere in the viv. They also DONT need watering in the viv. Every two weeks I take them all out and soak them in rain water/tap water over night, leave them to dry a few hours and stick them back in the viv. Easy! The second plant I have in there are carex grasses. These are durable grasses from NZ. They have to be planted and watered in the vivarium of course but this can be done without issues. I water mine roughly every other day. I use a pipette and inject the water in to the soil (its covered by a layer of sand). I get a very small spike in humidity after watering but it soon settles back to 13%, this is not unhealthy and quite normal in the wild with the morning dew and all. I have had them in there almost two months now. The two smaller ones aren't doing great, however I think that's down to being trampled all over more than dehydration. The larger carex I have in the centre of the viv is doing really well and the two smaller ones will be replaced by larger ones any day now to give them more of a chance to withstand a constant beating!
So as said it can be done fairly easily. You just have to ensure that the plants you want to use are safe. Tillandsia are fine, I believe so are bromelaids(?) and of course carex grass but that's all I know off the top of my head. Research and find the plants you want and then check on here. My advise, go to
here and choose from the wide variety they have available. Or PM Gill from justairplants on here and she will help you choose as she did for me, some hold up better in the heat you see.
as said, locusts will try to eat your plants but they way I see it is I have a fair bit of greenery in there plus fresh veg and I try to minimise the amount of locusts in the viv at one time by feeding one at a time when I can. To this day there is only one plant I can see with minor bite marks, no problem, bit of free gutloading! :lol2: Oh and my beardy doesn't touch them.
Sorry for the essay! Hope it helps.
EDIT: Shameless plug but I have some basking sites available
here and would happily incorporate some tillandsia on magnets if it would be something that would interest you. Of course it would cost a little extra but I can get the tillandsia from Gill, mount them on magnets and mount the magnets on/between the rocks... Job done! Otherwise, ignore that last paragraph and do it yourself! Hope I helped, Tom.
