OP, officially spring begins March 1st.
Unfortunately the weather doesn't always know that!

We are just about thru with the nights of frosty lawns. It could dip that far down once or twice still, but only maybe. Problem is, there's no way to know for sure around here. Weather is quite unpredictable. :upset:

You can sow in greenhouses and hoop covered rows now, but most people start things indoors from end of Feb. and then bring the seedlings outdoors when there is definately no more frosty nights.

The season ends in September on free land and in October in greenhouses.
I'd say we have around 7 months of mediocre growing season.
But we grow fantastic apples, pears, plums and cherries here in our region!

We have a very mild climate, so never gets very cold nor very warm.


Cheers - Jens

Finally spring is here and I can get to work!

Here are some pics and a timelapse of me and two of our kids wheeling in the IBCs.

I want to make sure my suspension can handle the weight og the top DWC bed.
I basically just use a piece of rope tied into the frame in a cross.

And this is how the layout will be inside the GH.

The bluebarrels will be in a frame built like those Donald Porta has made.
The IBC at the end of the blue barrels will be the sump, the one opposite that will be the media filter.
I will cut the tops off all of them and use them as DWC beds.

So basically I have commandeered 1/6 of our lawn for my GH. :D
My wife still thinks we should have a lawn, I really rather want to turn it all into a small urban food forest.....

Around the back of our house there is a 4 x 12 meter strip of grass which we don't use.
I'll probably turn that into my orchard....

Tomorrow should be another sunny, dry and busy day!

Thanks gnoib,

Hopefully I can finish cutting all the IBCs today and get them lined up.

I didn't have the best of luck running my temporary system with the IBC top cut and flipped... of course I bought it already cut so it wasn't cut how I would have cut it, but I put 2x4's under it for support and still had problems with it sagging in random places causing water to be above my gravel in some areas and overflow the bed in other areas... I could have cut my standpipe lower but I was using a standpipe that was for something else so didn't want to cut it that way I can take it back to it's original use if I decide to later.. if you are just going to run DWC in them or a lighter substrate then maybe it won't be as bad, but I had pea stone gravel in mine which was heavy. Alternatively I guess just cutting the standpipe to the correct height would have probably fixed the problems I had.

Hey Rob,

You're right, they do sag. But I'm running them all as DWC so it really doesn't matter for me.

As you can see in the pics, suspending them on rope works super fine. I've had one standing for a week full of water and had no problems.

My 3½ yo daughter (whom my wife claims should have been a boy) is very much into dad's projects.
My problem is actually that I have to keep her at bay when dangerous tools and operations are going on. Otherwise she is constantly around my ankles sticking her nose in eveything! :funny1:

I now have all the tanks cut and flipped. Next is plumbing the tanks together and building the stands for the blue barrels.

The blue barrels will hold media. Blue granite in the bottom and Hydroton on top. I also have some fine gravel from the old system which originally came from my aquarium. It's still in the old system, so fully colonized with bacteria. I will transfer all that to the new media beds to get the system cycled ASAP.

I'm building the entire system before I put up the polytunnel. That way it's much easier to access for construction.

I count on having the system running during Easter holiday so I can receive my Trout fingerlings after Easter. I'm also going to get some Catfish if the supplier I have found has some of suitable size.

Things are coming together quickly over there Jens. I am super impressed with your rope suspension system.

Thanks Brian.
I got the idea for the DWC on top AND the rope suspension from a picture I once saw. I've actually tried to find out who made that setup that I saw, but without luck.
Anyway, I found it a neat way to do things cheap and effectively. The rope is good, because it doesn't get affected by the water, nor does it take up much space.

Right now I'm waiting for some t-connectors for my pipes so I can get the plumbing going. I've got everything else lying here, but the t bits are missing. Without them I'm stuck......

Looks great. I'm happy to see your daughter is interested. Keep a close eye on those ropes. They will stretch over time, and sunlight exposure at the ends may eventually cause them to fail at the knots.

If possible I would recommend 3 or 4 wood slats thru the IBC cage supporting the DWC on top, maybe 2x4's will work.

The rope looks like a great idea, just be cautious about the lifespan.

Thanks Rick,

The rope is a uv stabilized Nylon for outdoor use, so I hope it will last a while.
I want to give it a shot as it keeps the beds lower and I just think it looks less bulky this way.
I'm also going to wrap all the IBC cages back and sides in the same material as the ground cover to block out direct sun and keep algae from blooming in my tanks and beds. The front of the cages face north so to begin with I will keep them exposed and see how it works out.

A really big one... Actually I think the saying my dive instructor uses is if you don't know how to tie a good knot, tie a lot of knots.

I found it now. It's called a clove hitch.

My grandfather who was a captain taught me to tie knots.
The clove hitch was used everywhere!
