UPDATE:
2 of them are doing well now that I have balanced the watering and heating. However, I've been observing one of my my flowers and I've noticed that it's not doing well (it was bought in different non-specialized store) and some of roots inside have even got this weird frost looking cover, which probably can be a sign of rot. There are 2 orchids in that pot, one of them is blooming, other is just trying to grow it's stem back (or not), I just ordered some supplies for re-potting, I'm going to give a shot and re-pot both orchids into 2 separate pots once my delivery is here.. I'll try to use a mixture of bulk, Aliflor and a little sphagnum moss in the bottom.
And the other ones so far are doing okay, so I'll just leave them alone for now
Please let me know if there's something else I should know. Thanks for your help
