Sometimes rooting begonia leaves can be very slow. A lot of that depends on several factors such as the health and age of the leaf, rooting conditions (soil, temps, humidity, light, etc.), and the season you start it in. I think I read somewhere that summer and fall are the best times to root a lot of rhizomatous begonias (rexes fall in this category). Anyway if you got it to root, it could sit there for the right conditions to pup. I had rooted a beefsteak leaf in fall a couple of years ago and it didn't do a thing all winter but it didn't die either. Then in spring it finally started throwing up some small leaves. Talk about slow. I bet it was six months before it threw up some new leaves. Now I root most of my leaves by water rooting and always tent them with a plastic cup or plastic bag. I have several in the basement now that have rooted in a week and are ready to be potted in some soil. Then there are the oddballs. I rooted 'Lalomie' by water this summer and let it sit in the water for a couple of months until it had pups at the cut stem sitting in water. I finally potted it up and it is slowly growing. In the same glass of water I rooted two 'Martin's Mystery' leaves and stuck them in a cookie jar the same time I potted up the 'Lalomie'. The cookie jar is full. Go figure. Then I put four leaves of 'Lalomie' in the same glass as the first leaf (I cleaned it out first) on Feb 22. I see it now has some small pups at the sinus of two leaves and all 4 stems have some roots. That is slow but it beats rotting or drying up and blowing away. My best results now are from water rooting for most leaves. Some varieties are so easy to start by leaf that sticking them almost anywhere will root (that includes gravel, sand, Perlite). The two easiest for me have been 'Joe Hayden' and 'River Nile'. My latest experiment is 'Pink Diamonds'. I put four leaves in water, four in Perlite, and eight in a big aquarium with some on the edges of the aquarium where it is wetter, and some in the middle where it is hotter and drier. This way I can see which is better for this variety.

Hello azee_2009, OK I originally thought it was going to be a rooftop greenhouse, but after rereading your second post I wasn't sure anymore. As far as the construction I used to build mine, it could be applied to a rooftop situation. By just building a sturdy base for the electrical conduit posts/poles. Similar to the baseboards I made for mine. The weight of it will keep it in place. The poles for my greenhouse only go down in the ground about 8-10 inches, and there is no cement holding them down (just the weight of the greenhouse structure itself). I just posted the link/information to give you some ideas. That greenhouse looks much nicer than the one I built. Although much more expensive too. Not including the subterranean system, and the hydro systems inside, I built my whole 10 by 20 foot greenhouse for about $800. Ya, heat will be challenging. Our outside temp today was about 92 degrees, but the temp inside the greenhouse was 108 degrees. When the temps here reach the 120 mark, greenhouse temps would likely be around 140-150 if I didn't have a multi tiered cooling plan. Cross ventilation is great in some circumstances, but it wont help much at all to blow 120 degree air on your plants when it gets hot. Given the best circumstances, swamp coolers may bring the temps down about 20 degrees. But if humidity isn't carefully controlled, they may only provide a difference of between 5 and 10 degrees at most of cooling effect by themselves. Just to clarify, when I mention high humidity, I mean in the greenhouse. That will depend a lot on temperature inside the greenhouse, water vapor given off from the hydroponic systems inside. Not to mention the biggest factor, how many plants your growing, and how big they are. Plants breath out water vapor (called transpiration). The water vapor (relative humidity) in the greenhouse will get higher and higher unless it's ventilated. But ventilating a cooler greenhouse with the (hot) dry outside air will only heat up the inside of your greenhouse. I have searched the web a lot & every where i have read that Double Poly Sheet that makes air pockets between them retain heat within the greenhouse & reduce heating costs about 50% compared to single poly coverings. So how would i be able to use it. As i have to fight against high temperatures. The air pocket in-bitween the two layers of poly is an insulation pocket. Air pockets are the best insulation there is. Insulation will protect against heat just as easy as it does against cold. If your greenhouse is cooler than it is outside, the insulation (air pocket) will help keep your expensive cool air inside the greenhouse stay cooler longer. If you have no way to cool the inside of the greenhouse, then it wont help much. The air pocket is just insulation, not a cooling or heating layer. It just helps block the heat transfer from one side to the other. Blocks heat from getting out during winter, and blocks against heat from getting in during summer. The 4-5 inch's between both layers you describe should be plenty. Typically it's only about one inch between layers. Though I would expect that you will still get much better results with a air blower between the two layers. The reason is if you blew the cooler air in between the layers, it won't give the air pocket a chance to heat up. Thus keep the heat transfer between the inside, and outside layers to a minimum. I want to know the link & name of software you are using to create 3D images. I want to download it to make someone understand what i mean. I use a free program called Google SketchUp. They have a pro version you can pay for, but I've always used the free version, and like it very much. I save all my drawings into a folder so I can expand on them later without starting over. Before you post your drawings, you'll need to remember to export and save it as a 2D image. Otherwise it wont be in jpg. format, and people that don't have Google Sketchup wont be able to view it. Before I built my greenhouse, I did a lot research online to figure out what would work the best for me, as well as my budget. Here are a bunch of the links I have got bookmarked from those searches. I know it's a lot to read over, and it's been a long time sense I looked through it myself. But a lot of it is in lists of topics. I just read through what was of interest to me.

Good Luck to you Carol, the last time I spoke with you I planted my Easter Redbud. That was last week in April. Well, Carol, you should see it now. Just bloomin beautiful! The buds on the tree have almost been spent, and now the leaves are popping out. Love it. I,m very happy with it so far! Yes, you are right about the cost of those trees, I paid $100 for mine at the local nursery. They gave me a 3 yr. guarantee on it. When I get my camera working, I will send you a photo of it. Karen

I received my wonderful box from Jeanette! It was full to the brim with bright orange and black wrapped surprises! I got: a wonderful Halloween kitchen towel. I love to change my kitchen towels for the season and didn't have a Halloween-themed one - thanks! a cute pumpkin votive candle holder with a scented candle in it a black and orange paper lantern a wonderfully scented potpurri mix a halloween wind sock a spider web wine/champagne goblet (so cute!) a spider on a spring a silver starred Halloween hat (sorry Jeanette - no digital camera to take a picture - my daughter kept saying "you're not going to wear that in front of my friends are you? - LOL!" a spooky hanging ghosty that emits an eeery sound - scares the daylights out of my little dog......... mummy's passion fruit tea bags and a ghost tin of chocolate kisses (oops all gone - how did that happen he he) Thanks Jeanette!
