Hi. I've been a lurker in this forum for a few months now, and never wrote anything, but now I have some doubts that I really want to clarify...

I fell in love with plumerias and I bought, a month ago some seeds, (and now a cutting) they are doing great. It's currently winter here, so I have them inside close to the window, on an improvised mini greenhouse I did with cardbox, coated with alluminium foil inside so the light reflects and then at the top and sun-facing side with transparent plastic bag. I also have a little device my dad made me that you can place the needle inside the soil and it will tell you the soil's humidity so you know when to water. It also tells you the temperature in your house and the room's humidity level. (or if you plant them outside). It's a very sensitive device which is good.

Anyway, as I was saying, I couldn't resist the plumeria calling and bought a cutting from the canary islands on the 24th December this year. it will arrive any day now, and I know the root development will be slower, but still, my doubts are: should I let the cutting dry for a week and then plant it in completely dry soil? (I bought soil that has perlite and agrosil (which stimulates root growth) I watched Jacob's Plumerais video on planting the cuttings, and he says to mist the soil and not water it anymore untill you see leaves growing. Does it apply to winter indoors growing? Like, should I slightly mist the soil before planting even if it's winter? Or should I plant the cutting in the dry soil? Also, what are good bulb lights (I really don't have the space plus this house is my parents so i can't stick thos long tube lights in the ceiling) for growing plants? We have a new and unused LED U-shape 6500K bulb that i plan on using on a flexible lamp and put it right above the plant, since it has a part that holds to furniture. Is it a good one? What other cheap lights can I use? And when I plant it, would it be wrong to put the potted cutting inside a ziplock clear plastic bag to act as a greenhouse? Will it rot the cutting, or help it?

PS. I forgot to say we have a heater inside since it's winter. hope it helps the plant. We often open doors so air circulates.

Thank you very much and so sorry for the long post!

Welcome! SergioBarroso

Dormancy means there is very little cell activity, so the rooting process will be much slower during this time. If you want to use the soil mixture you have chosen, DO NOT water at all. You may mist the stick from time to time since the air in your heated place will be quite dry, and I recommend bottom heat. Don't cook it, mind you, but a warm bottom environment encourages root development.
The roots will all start to develop from the very bottom, so I would say just use a couple of inches of soil, do not actually plant the cutting, you can put it in a narrow container (a plastic water bottle is fine, you can watch the root development and cut the bottle away when you are ready to plant it).
My very first rooting was (accidentally) done over the winter, with the cutting sitting upright on top of plain sand.

Good luck and keep us posted on your success.

Thank you! I have now my seedlings under the artificial light and I was wondering, when my cutting arrives, should I place it directly under the light too? Or it will burn?

It won't burn, just don't put the light too close.
