Sorry Tru, was trying to be funny, but have tough time conveying that in text. The plants would be fine (theyíd absorb all the non green spectra of light like they always do), but because the green light had been filtered the green light would not longer be reflected on to your retina after it hits the plantsÖso the plants wouldnít appear green anymore.

202
Problem with the green filter is u wonít want any plants if they are just grey instead of green.

203
Brian, Iím In the middle of the city and I run my 1800watt leds them from 7:15 am to 8:15 pm (when it is cloudy/dark). it good for the plants, but more for the predatory insects that go dormant when the sun is <12h. We only get 6 hours of sun in the winter so the gh glows from About 4:30 pm onwards. Iíve asked around and no one seems to mind, I even catch people hanging outside and just looking at the plants in the winter. Also no one has thrown rocks at it yet.

204
Carolyn, you have birds and a pond! Whatís in your pond?

Cherimoya dude, There is a nursery called ďsage gardensĒ here just outside the city. They keep at it a 15c in winter and he uses geothermal (the ground freezes to 8ft here) He is all into organically as well, take a look at their website. Heís a pretty nice guy and Iím sure if u have his shop a call heíd let u know how week it works.

Brian,
Im sure youíre right. Iíve double double pane low e glass, and with cleaning the inside glass 2x year, i usually loose 30% of sunlight according to my light meter (umol/m not lumens). Itís maxes out just over 1000umol even during the winter (but I try to have high co2 levels (2-3x atmospheric) so I want as much light as possible).

206
Btw when doing research for my zone 3 greenhouse I did find company that offers glazing with quintuple panes (yep 5). I wonder how much light get through?

207
Brian u are spot on about multiple cold cloudy days. When that study was done winnipeg was know for cold clear skies in winter (-40). The past couple of years the winters are milder, which is nice, but the sun is gone too. This week is really the first time weíve had sun for 2 months.

I used to put aluminum backed styrofoam panels on 40% of my glazing to try and capture heat and help contain reflected light. It did help with the heating but it still decreased the available light and I had bunch of citrus dieback as dark hot rooms are bad for plants.

Also cool idea, itís nice to see Iím not the only one who makes models and tries to invent things.

I got an unnamed cultivar from pine island nursery that is about 9-10 years old. Itís fruiting/flowering for the first time right now. Does anybody know what variety pine island used to sell?

209
In Winnipeg, just north of you for a 225 sqft (very well insulated attached greenhouse) costs up to 4 dollars a day to keep ultra tropicals alive during the coldest winter months. At the university of Manitoba they built a Chinese style greenhouse that was passively heated almost stayed above freezing all winter (had hot compost piles in it). Here is the link to the paper.

Drymifolia, I thought about doing some arduino controllers, but didnít have the patient or brainpower to figure it out. Donu have experience with that sort of thing? Also I was wondering do u have them set as controllers of just monitoring? Also how reliable are they wrt breaking down? Iíve used a bunch of inkibirds to control my lights and humidity and they are terrible for breaking at 14-16 months and I was about ready to throw in the towel with them and try to find something new

Tropical Fruit Discussion / Re: 2023 Mango Season
« on: January 27, 2023, 05:00:59 PM »
Has anyone grown them off season before? I was curious if the quality is lower. I struggled with mangos for years (killed so many trees) and finally grew my first one (ate it 1 week ago). My plant (Pickering) flowered in the fall cause I left it outside until September. I got my first fruit around jan 10. Tasted great, but then again Iíve only had poor mangos up here in Canada. So I was thinking I could try and stagger my trees and get them fresh all year.

213
Drymifolia, I like the data tracking. I probably would have figured things out faster if I had done that. What did u use for a system?

214
Iím jealous of people that donít need containers. Looks great, was it tricky to take the roof off and add the panels . Whatís the soil like? Also what do u do for ventilation? Some of the temps are kinda high. There is a lot of research for university of florida and they show that if u exchange 1 air unit per minute in the inside temp will be max 4c more than outside on the sunniest day possible. With high air exchange and a misting system I can get my gh temp 6c less than outside even on the hottest day. Mind u I have a tiny greenhouse and a jet engine of an exhaust fan.

Hi ! I've got a little greenhouse in Vancouver Wa, zone 8b. I have a pouteria obsession after eating mamey, so I've managed to fill my greenhouse with a bunch of plants that will probably get far too large in a few years. Currently I just have a cheap plastic greenhouse from Amazon that has decimated my heating bill this winter, but I am looking to build a permanent lean-to against my house this summer. I just put 4 pradosia Brevipes seeds in pots so I'm hopeful those will sprout. Also have mamey, butter sapote, ross, ducke, P transclucida, P viridis and P venosa growing.  I also have a some eugenia and plinia growing. This forum and its members have opened my eyes to just how many tropical fruits there are, and how few are available in Washington state. But we get amazing blueberries, raspberries, cherries and apples up here. (which I have growing outside of the greenhouse)

Never tasted  a Mamey, . I heard it tasted like pumpkin pie? Also I had grown persimmons for a while inside and felt they werenít pumpkin piey  enough to justify the space. be careful about the outside of your house. Mine actually sits on my roof and is also against an exterior wall and I made sure I designed it so it is fully sealed and completely separate from
The rest of my house. I found tropical fruit hunters blog after I had built mine and was lucky I was able to avoid the moisture infiltration problems.

I've had a 1725 SQFT GH in SW Texas at 4500 ft elevation for 18 years. Started out growing mostly stone fruit and citrus. That became a fig nursery business the last 7 years but now I'm going back to stone fruit with the addition of mango to spice things up. I'd like to compare my best stone fruit to good mango.

Stone fruit will be on the cool end near the wet wall and mango on the warm end near the exhaust fans. My main concern is getting enough chilling for the stone fruit while keeping it warm enough for mango. In the past chilling was easy by heating to 37-40 at night and running the evap cooler by day. I could achieve an average of 16 Utah hrs per day during chill cycle. 45 days was enough for 720 chill hrs and everything bloomed well.

My plan going forward is to heavily shade the stone fruit during chilling and put up one or more curtains between the stone fruit and mango to help keep the mango warm. Also some plans to maintain the soil as warm as possible for the mango.

I think my mango climate will be better than any place in CA. Highs will be 80s and 90s for 270-300 days a year and mostly 60s and 70s the rest of the time. Nights in the 40s about 45-60 days and 50s and 60s the rest.

My soil is a well drained loam. Everything grows very well, maybe too well. I tried a Raga puri banana once and it was so vigorous I had to take it out before it shaded out everything nearby.

That sounds like perfect growing conditions for everything. Whatís your outdoor temps in summer and winter? How do u manage humidity in winter? Do you feel
Like itís almost too Much space? I find I get overwhelmed with my tiny gh and my houseplants once I start doing summer outdoor projects.

217
It does sometimes drip from the top. The ceiling is 45 degree so it usually rounds down the walls. I actually got a proper thermally broken frame and I run a dehumidifier in the winter (dessicant so also heats) so water only condenses at -10c outside and the frame will frost/freeze up at -25c. I have a ceiling fan that gives good flow so I donít usually have any fungal issues at colder temps. I did have butter lettuce rot and get fungus this year as near the windows where itís cold (55f) and 85% rh. Rocket and arugula did fine though. The only Fungus issue I have (it may be that some other growing issues are from Fungus?) is ancathranose with some mangos.

218
I canít get rid of scale and donít understand it. My large red lime and Meyer lemon were completely free for years while others were infested, now this year only they have it. Yeah Iím stuck using hose in summer and spray bottle with soap/rubbing alcohol And a toothbrush in winter. Iím gonna try mass rearing of lacewings next year, scale destroyers donít work at all for me (tired them twice).

Lol Ahhh good olí Nick and Jesse, I canít believe an Aussie had even heard of that show. Iím pretty sure I was forced to watch that in school as a part of Canadian heritage studies.

220
Yeah itís too cold out sometimes -40C, Iíve some some microclimates in my yard that allow me to keep some small zone 5 (paw paw seedlings) and Iíve tried doing peaches in containers (zone 4/5) and store in the garage or cold part of basement but I canít seem to keep them alive for more and 2-3 years. Yeah I was thinking about the cold box idea too, the problem here is most winters (not this one) are extremely sunny, so anything enclosed really heats up. Itís actually why I decided to build one 7 y ago (itís actually on the roof of my kitchen). It works so well that here on a sunny cold day itís -30f outside and over 80f (26c) inside. The past 3 years have been much milder and cloudy so I put up grow lights as I had a lot of citrus dieback a couple of years ago. Also the beneficial insects I have can start to go dormant with <12 sun a day so it serves multiple purposes.

Talking about feijoias (the only ones Iíve ever seen/eaten are min own)Iím thinking my greenhouse runs to hot at 85F for them To taste their best. I had a friends parents visit from New Zealand, and while I was very proud to show them I could grow their favourite fruit in the middle of a cold winter, they did not think they were anything like the big juicy fruits that they had at home (they actually snickered when they saw them). Whatís been your experience with taste/temp?

Also I donít find them to be partially self fertile at all like some People on this forum have said, and getting cultivars that flower at the exact same time for cross
Pollinating has been a challenge. My nikita rarely had fruit cause the others started flowering just as it finished.

How do u grow at 47c? Shade cloth and misters?

222
It looks really nice to have a setup with the birds and sitting space. I have too many exhaust fans so animals are a no go for me. yeah itís pretty tight, only 225 sq ft so I pack as much in as I can. I did have to room to fit a hammock which I used during lockdown.

They all stay inside all summer, Iíve figured out how to keep the temps under 86F even when itís 100F and sunny.

Iím still trying to figure out how to perfect the humidity for mangos (too dry mildew to wet ancathranose). I also think I need to make a mini greenhouse for rambutan, lanzone/Landsat sand mangosteen as I think they need even more consistent high humidity to grow well they look a little sad. I also use digital Controllers for the humidity and they always seem to break after 18 months which makes it hard or delicate plants.

Iím also trying to find out how to get enough chill hours near the windows to grow dwarf nectarines 800h. I canít get low chill cultivars in canada. I get enough for feijoias 150? and did peaches (400) one year before I got ultra tropicals and had to turn the heat up a bit. Iím hoping the mini greenhouse will let me turn down the winter temps to save power and get more chill.



223
Birds too! Cool. Iíve had lots of luck with parasitic wasps for aphids. Interestingly they showed up one summer and been able to keep them going for 18 months. I think the trick is to have some sacrificial plants. You can see one of them In the flower they are super small.

What to quails eat, I have some sacrificial plants loaded with hard scale and I wonder if they would pick them off.




224
Yeah Iím not sure if organic are the way to go. Somethings seem to produce well, others not so much. I think Iíve finally figured out the climate control (sort of). Now working on pests, soil and fertilization. The problem is I donít know any other people trying this stuff up North so I donít know if I just suck at growing certain things or if they just take a while to produce. Be warned I have a high electricity bill but hydroelectric power here is abundant and we actually have a surplus.
