Yes they are supplemental for my northwest facing windows.  Not great but it's all i have...on the plus side they are very large windows.  Though nothing like the south facing windows where I use to live.  I had only one small light as a supplement at that time, but everything was very happy with that southern exposure.  The plants put on lots of dark green compact growth even in the winter.  Its tough to beat natural light if you can get it.

No problem, I just ran into the website a few days ago myself, while looking for photos of guava varieties who's seed I had ordered.

organic cherimoya in the midwest goes for 12 to 18 dollars per pound

Very cool find Raul, should be interesting to find out the exact info on this cycad/palm...and if it is a known species/sub-species 

I've been growing cuttings for the past year in wisconsin...one thing I've noticed is that on bright sunny days they can take a lot of water/rain and still put on good growth, but even during the summer they didn't like the combo of wet and cloudy.  I have them inside now with supplemental light and they are slow growing, but seem to do best growth wise in the week before I  water them.  (I am watering them only every three weeks or so) so keeping them on the dry side might help.

Besides the stuff already mentioned...kiwis, some guavas, raspberries, persimmons, grapes, loquats, asian pears, elderberries, all stone fruit (plums, plouts, apricots, peaches, cherries) and maybe satsumas in a protected location

I would second the not disturbing the roots if it's a pawpaw.  The one pawpaw I bare rooted and put into the ground had the roots and stem turn black and very shortly died.

Not a ton of leaf growth on the three year old pawpaw, but some trunck growth....and decent growth on second year pawpaws

thanks a bunch dragon, fyliu, and ricshaw...I'll ask around at my local nurseries and home depot and if not I'll order it online

I'm not growing any myself yet, but they've started to really grow in popularity among fruit growers in Wisconsin as an alternative to blueberries in parts of the state that have alkaline soils.  I haven't heard anything about them being invasive here, but Kentucky might be a different story. 

the seedling pawpaws here in zone 4b are starting to leaf out

That's a very healthy looking jackfruit tree...nothing like some good shade as temps start to climb.

Hey youcan't, unfortunately our local nursery selection is mostly limited to ornamental tropical plants and is only slightly better then when I lived up north. Some will order stuff for you on request which is on option if you don't want to hassle with problems due to shipping, but the cost usually ends up being about the same.  I mail order most of my stuff which I've kept mostly to seeds to keep my costs down.  With a greenhouse though I would recommend getting grafted plants to insure you're getting quality plants and giving yourself the best chances for good fruit.  Looking forward to how your greenhouse comes along...keep us updated.
