green house

[jonsunnycoast]

what is the best position for a small green house for seedlings only have a small 2ft x 2ft x 5 ft high one with some shelves, how much sun and what time of day ect

[Steve Mac]

Geez mate, so many variables? Wouldn't you just put a thermometer in it yourself, and move it around if possible for different seasons, to get more heat or shade.

That's what I would do. I would move it according to what I had in it and what they required.

[jonsunnycoast]

yeah just trying to get a gauge on where to start this side of palms is pretty new to me and I want to get good at it so if I get access to some really cool seeds I don't stuff it up

That is a very small greenhouse. When volume is small like that temperature inside will fluctuate greatly so if you have it in the sun in QLD at any time of the year it will be roasting inside. It will also lose heat quickly too. I imagine the main reason for having a greenhouse in QLD for seedlings would be to avoid cold nighttime temperatures in winter. Due to it losing heat quickly it wont be very effective at this. I notice that you have a shed/building in your backyard. If you want a very good greenhouse I recommend replacing the roof of this structure with polycarbonate twinwall material-you can buy it from Bunnings- is cheaper, easier to work with, stronger and better insulating than glass. You then would have a large volume that will hold temperature for some time. If it gets too hot you can place some shadecloth over the top. If it is hooked up to electricity you can set up a fan and heater inside to maintain a more constant environment-I think this is very important when raising seedlings. I

I also recommend a heat mat to provide bottom heat. I am currently germinating seeds growing up palms in a greenhouse that was originally a garage-who needs a garage? The material I used was twinwall polycarbonate. Pics in my Frankston Garden Post.

shed in fully plastered on the inside it is a reptile shed / man cave  I only got the small green house because I have some hydriastele beguinni seedlings that I want to get big asap for planting

[Sir Oxylon]

OK. Make some observations on what temperatures it gets to in the greenhouse perhaps before you put them in so that you don't fry them. Man caves are awesome. I am not allowed to call anything a man cave around my house because my partner suggests that she hasn't got a woman cave. A friend of mine then said that the whole house is a woman cave

Jon, you dont need shadeclothe on your side ( imo) of your shade house , an easy n cheap  way is just tie tightly wire above (  4  to 6 mtrs apart) as long as you like and put the s/clothe wherever you want to.

Its weird that the US they  call their "Hothouses" which are plastic covers Greenhouses and they give no shade  But, nil against the  US as we both( AUS and  USA) have  "Lots" of words that mean different  things..

If the wires are long you can put s/cloth wherever you want and  plant underneath for a few yrs as well till they get up n strong, plus you can tie the wires wherever you like.

Bunnings has the sewing needle annd string or you can attatch with the clips.

All best with whatever you do.

I have mine facing south so I can harvest all day sun to maximize growth rates.

I also have the entire structure covered under 32% shade. palms still can burn under this shade but it helps acclimate them 2 X's faster than 60-80% most growers use in California.

Obviously though here in the southern hemisphere the reverse applies and it is better to place shadehouses on the northern side............... Mine however is in the middle of the paddock

Jon,

why do you call it a Green house and not a Hot house which it is, and what it is  called here in Oz ??

I honestly cant tell you just called it that its the clear plastic so probably be more suited to being called hot house

not at the moment can get some I have just put in inside the shed right against the glass door its heated in there for my reptiles and that "hot house" will keep the humidity in

[jonsunnycoast]

think I am going to have to build a larger one for future seedlings

Thanks for thr reply Jon, I know Oz is becoming very Americanised, but we decended from convicts so lets stay as Aussie as possible for as long as possible.

Here it is Josh.......... It is currently raining so I didn't want to take the camera outside to get a full shot.......... It is 14 metres (46 feet) x 7 metres (23 feet)  and covered with 70% shade cloth..... It is pretty much full and I need to empty out some space for new seedlings coming along !!

[Really full garden]

Pete, I think the name "greenhouse" originated in the colder northeast region of the US where there are cold winters with snow and most trees are bare for months. A greenhouse is where plants ,flowers and crops grew and were GREEN during the winter.A conservatory is a type of green house but refers to more ornamental displays of tender plants.

Here we call them  shadehouse , bushhouse or greenhouse , whatever their called , their essential in raising seedlings and rare palms . Andrew your greenhouse looks great but pretty full , I have room in mine if it get's too full .  Good to see a bit of rain too .

Richie, you need to read from the start as this thread is going from a Hothouse to a Greenhouse/Shadehouse. Jon, wants to build a HOT house 

Scott, thank you very much  for the Nthn hemisphere history re Greenhouse origins.

When germinating being rodent proof is vital. Heat is another, in our subtropical winter you can loose the whole batch before they germinate, if too cold and wet, like now for me.
