Forgot to mention I also have plastic containters filled with water on the soil for humidity.

You probably have a tropical hibiscus (Hibiscus rosa-sinensis), right? Not hardy where you live?
It sounds like your hibiscus is happy where it is.
One of the main concerns during the winter months is overwatering; I almost killed one hibiscus that I grew from seed this way recently.
It seems like you're doing everything right, including the humidity tray. One thing I will mention is to be sure to remove those trays occasionally to make sure fungus, etc isn't growing underneath them. I keep shells in my pots and I have to be careful of this.
Otheres might have more things to add, but I'd say, keep up the good work and you'll be rewarded soon!

You are doing everything right, congratulations! Watch out for spider mites and whiteflies and treat at first sign of the little buggers.

Also watch out for an every increasing collection. I had one red hibiscus several years ago, just like you. I now have about 15 of them in an indoor grow room with heavy-duty grow lights, fans and humidifiers. They are addictive! Have fun!

Thank you both for your feed back it's much appreciated.

Beach barbie, I do move the trays regularly by default- my cat keeps drinking the water, even though she always has a fresh bowl available. And I do think it's a tropical variety. BTW I love your name, it creates a warm image.

Watergal, I don't see any evidence of pests, but your comment concerned me so I sprayed the entire plant with insecticidal soap just to be sure.

On the under side of the foliage I do see some VERY TINY white powder like specs that rub off with the finger, too small for aphids. Any idea what that may be? And am I on target for March to expect new buds.

Thanks, Happy Valentines Day..

White powder-like specs...hhmmmm..... If they're not whitefly, then I haven't a clue, sorry!
As far as treating for whitefly and aphids go, you can just use a 10% dish liquid and water solution. It's safe, cheap and works great. Spray it on the tips of the branches and the buds, which is where the little buggers most likely are. Be sure to spray underneath the leaves also. I use it about once a week and I haven't had a problem all winter.
And Watergal is right about the addiction. I had three about eight years ago and I now have about 15 that are bloom size and at least that many seedlings.

Not sure about the critters but a good spray with the soap will probably keep them in line. Sounds too small for whitefly. Is it fluffy looking - if so, maybe mealybug, but that tends to cluster where stem meets leaf, not under the leaves.

With really good light and no pests, you might get buds by March. It takes a good 3 months after pruning a branch to get buds on it, more if the light is less than really bright or the plant is fighting insects. I wouldn't expect too much until May or later, although you might get a few sporadic flowers before then if all goes well. My heavy blooms start in July and go through until about Christmas.

Barbie, I am now watering about three times weekly, I'm doing this because the leaves are starting to droop but do respond once watered. I am concerned about what you said regarding over watering, but the plant does seem to need it.
A new concern:
Today I noticed a single clear liquid drop at the bottom of a many leafs, exactly where the leaf meets the stem. Any idea what this is and does it need any attention. Oh and the drop is sticky to the touch.

What is the tiny sap like droplet on my hibiscus located at the bottom of a many leafs, exactly where the leaf meets the stem.

The tiny powdery dots might be spider mites, which can be a BIG nuisance if there's not enough humidity and/or air circulation around the plants.

With respect to the droplets - I mention what that is in your separate post. They call the locations where they appear, "extrafloral nectaries", and the little droplets are a type of nectar most likely used as an attractant to insects.

Just wanted to report back to the folks who responded to my questions during the cold weather here in the north. My Hibiscus plant remains potted in full sun and is doing rather well, sprouting several new flowers daily. Thanks for your help and happy growing.

Glad to hear it! My hibiscus had a bad whitefly infestation over the winter and are outdoors still recovering. Had to do severe pruning because they were so leggy, so no flowers yet and probably not for another month. :(
