I had a honey tangerine a couple months ago and I saved the seeds (the fruit was very seedy!). I planted them and just about everyone germinated. I just put them in a moist potting mix, no bottom heat and no cover. I have no idea if tangerines grow true to seed and it would take an extremely long time for it to bear fruit, if ever. Most citrus trees are grafted but from seed they do make a very pretty plant and are fun to grow. I'd say go for it as long as you aren't expecting to harvest a crop of tangerines.

I believe the Honey tangerine is the same as 'Murcott', which, some sources say is most likely a hybrid between a tangerine and an orange (therefore a tangor). It will grow true-to-type and fortunately can bear in as little as 3-5 years, although that's only if it is growing outside in a warm climate with a long growing season (ie Florida). Indoors it could take much longer.
