Backyard Aquaponics
A place to discuss aquaponics

Aimed at those who have bought or been quoted on Polyweave greenhouse fabric. I'm thinking af getting a relatively small amount to use on my temporary structure I'll be building over my grow-beds. Although the structure is said to be temporary - it will probably be reused in some capacity so I'm thinking it may be worthwhile forking out the extra cash and getting Polyweave rather than just buying builders plastic which may not even last the 3 month cold period (let alone the extra month or so needed before some decent heat comes in the days).

The thing is, I've been quoted $12 per meter for the 3.1 metre wide stuff. This is from a place not far from me. They don't have anything wider than that, which is a shame because 4 metres would have been better for what I'm trying to do with this structure.

Anyway - I'm happy to pay a small premium given that I need to get the stuff to do the job on the weekend, but want to make sure I'm not being totally ripped off.

I may still go with the cheaper option and get clear builders plastic which I can get by the meter (2 metre wide stuff) for $2 from the mitre 10 just in town. Cheaper by the 50 or 100 metre roll I'm sure, but I just don't want that much. I may even do the top of the half hoop tunnel structure that I plan to make in Polyweave and the sides in the builders plastic. In fact, because 1 side is on a side that will get no sun, I may use panda on that side with the white side in side the structure to reflect the light.

These guys are always listed ..... $11/mtr.... 7 metres wide.... but in Vic...

What about Redpath VB???

What guys?? Is it polyweave or just normal greenhouse film? I have an a redpath pricelist around here somewhere, but it is a couple of years old. Will see if I can find.

Major problem is that I want to do this on the coming weekend and I don't have tiem to source interstate etc. Besides which, last tiem I checked, the freight made it not such a good choice when getting small quantities. If I was to buy 6 metre wide stuff, for this project I'd only really need 4 or 5 metres (that's with using something else for the sides.

I just got 9x16 meters of duratough from redpath on ebay for $50

Duratough is a lot cheaper than polyweave. Have found the Redpath ctalogue but not the price list - will keep looking. Even in the redpath catalogue, the polyweave max width of roll is 3.1 metres.

I'll check the local supplier to see what they have int he cheaper plastics l (like Durathough). A big advantage of this is obviously its greater width. Again - I am going to be constrained by the timing here. I have a window of opportunity to do this work this weekend. That window will then close, possibly never to open again

Here's the link to RedPath polyweave... has a link to the pricelist VB

Or maybe you could try the hydro table "cloche" tunnels... http://www.kerilea.co.nz/commercial.html

Pricelist.... http://www.kerilea.co.nz/CommercialPricelist.pdf

I've ordered some to cover my hydro tables for the mega system...


I know... not cheap.... and your peanuts are on the line..... not even sure if the nearest agent would have any in stock....

Just throwing things your way....

P.S. .... polyweave link says "2.4m (8') x 4m (13'2") width rolls ".....

Nah - you have to put a request in for the price list. That link does not go to the price mate.

As for that explanation of width - WTF does that mean 2.4m x 4m width. They do have a 2.4 and 3.1 as far as I know, but the 3.1 is either being discontinued or the place near me is ceasing to stock it.

I'll do some more searching around for cheaper stuff locally, but hands may be tied a bit on this. I have about 30 or 40 minutes after my boys Taekwondo on Saturday to go to the shop and get what I need - means my range of movement is well limited . Even if it costs me a bit, is not a bad thing to give the polyweave a go, because this is what I'm hoping to use for my big house eventually, so will be a test.

Yeah, you're right VB .... idiots.... I hate people that don't publish their prices....

The more I think about it - the more I am tending towards buying builders plastic for the first attempt at this structure. I can always replace later on with something better if it perishes before the warm comes through. Hell - I might recoup the cost by having the time to shop around for the other fabric anyway and also I avoid the risk of stuffing the good fabric up while I am designing the structure. I reckon I'll need about 21 square metres for the top (so thats $22 bucks) and about 9 square metres for the side that will receive sun (another 9 bucks - plus a bit because of the need to use 2 pieces to get the necessary height and width). For the other side I'll use some Panda I already have (was expensive, but I'll not cut it and therefore can reuse another time). The back of the structure will be the shed wall - which I'll probably cover with polystyrene sheets to assist with insulation of the greenhouse and also reflect some light back to the plants. I've had another thought for the back of the greenhouse which I will post to the 'should VB sell his barra' thread'.

Before you go spending to much i have thermomiters al over my glasshouse on a hot day the ambient gets to 40 deg theblack polly beds get to 20 deg the 1000 litre tank [with only air gets 18 deg]. Overnight [without heaters] outside 10 deg ambient in glasshouse 11 deg the beds [no pumping ] drop to 12 and the 1000 litre drops to16 deg summing up in an un heated glasshouse the only gain is the high daytime temps warms things up

Yep - its the warming up during the day that I'm counting on F&F. I rckon it will be worth the small investment. Given thte temporary nature of the structure, I'll be using some of the 200 metres of 32mm PVC pipe that I have for the half hoops adn various braces. I'll also be using a bit of wood to secure the pipes to the shed and to the ground. The only real cost shoudl be the plastic.

Thanks for the temps though mate - it clarifies a lot. Even if I just get the 2 degree gain in the day it'll be worth it. What you have not been able to test, given that the greenhouse is in place - is what losses may have ocurred on cold and windy days etc, if no greenhouse.

Funny you should say that last week we had a few cold and windy days the outside system got down to 11.4 and the glasshouse beds were12.6 and the 1000 litre tank 13.6 deg that was before i realised the heater had blown out

How about 7.5 metre wide for AUD $11 per metre??
I've got 7 metres coming,,,and they don't charge excessive postage.

Always willing to help a fellow warmer is better enthusiast.
