4 of 5 Phals with new spikes. What to do?!?!

[Shikitita]

Hi everyone!

How are you all doing?

It has been a few months since I popped around here as my orchids have been doing pretty well so far. Mainly thanks to your advice.

Basically, we moved to a new place at the end of August, which really worried me as it probably would stress the orchids out or something. I placed them on the windowsill in the kitchen, even if that meant not being able to see them all the time. It faces North and we have no buildings in front of it, so plenty of light (and humidity) for my babies at least!

After cutting off their spikes round at the base (I already asked about this around July), they have been growing like mad since we moved here! New roots, new leaves... I barely recognised them!

And now 4 of the 5 phals I have are growing new spikes!!! In only 3 weeks they have grown more than 3 cms!!!

Now my question is... What do I do? I know I have to attach them somehow to the guides so they won't grow "horizontally", but I also know it's not good to put the guides in the soil just like that as it may damage some roots. Any tips or advice? Would I have to repot them so I can put the guides without any risk of damage?

I am so excited I hope they keep growing this well!!! Just need my favourite one of the 5 of them to start growing a spike as well, and I'll be the happiest person in the world!!! ^_^
