hi, i am thinking of buying a wilma 8 pot system, but wondered if there are any of you fine people out there that can advise me if they can leak?
Ive got the 10 pot, which is essentially the same as the 8 pot apart from the top tray holds 10 pots.
I have found it to be a wonderful system. Much better than my old cheap NFT. Easy to maintain and certainly no leaks. There is no where it could leak from.
Would reccomend the Wilma.

Imho it has its bad points altho its an allround good system. Bitch for res changes tho...
The main feed pipe where the drippers attach to used to leak, i had to use silicon to seal it up.
Now i use an 8 branch manifold connected to hose pipe which is fed from a small water butt - much better although i still use the wilma bottom and top trays to hold my rockwool blocks and to collect runn off.
Id say make ur own drippers sytem either using the 8 branch manifold like i said or use one of those topspin 12 dripper things depending on how many swirls u want to grow.
Im not really a fan of re-circulating systems anymore, i like aiming for zero runn off now and the swirls get new nutes everytime they love it|!
If u still decide to use wilmas prop the bottom tray up at one end a bit..u'll soon realise why.. i just used to chuck empty 2 litre mineral water bottles under there with the lids on so they dont squash...

I have a ten that i use to great effect, res changes are simplified by plumbing into the mains.
1. Cut off the end of the solid feed pipe.
2. Attach a legnth of hose (50-75mm) with jub clip.
3. Attach inline tap.
4. Attach hose linked to waste.
(5). Add inline taps to all dripper lines.
Water can now be drained from the system by turning off the inline dripper taps and turning on the drain inline tap and res pump.
1. Measure up your Cistern Valve from a toilet.
2. Cut slot in the end of the bottom tray to fit valve.
3. Attach a hose fitted to the mains water via a tap.
4. Turn on tap to fill res.
5. Use fine adjustment on the valve to get the required level.
Now the system is set up you can completely refresh you res without the use of chocks or towels etc.
When the main pump has taken out all it can, leaving say 2% used nutes, simply fill your res with water, drain and repeat a few times.
100% Nutes - 98% volume = 2% Nutes
2% Nutes +98% Water = 2% Nutes or (v1)
(v1) - 98% volume = 0.04% Nutes
Fill... = (v2)
(v2) - 98% volume = 0.0008% Nutes
Fill... = (v3)
(v3) - 98% volume = 0.000016% Nutes
Fill... = (v4)
(v4) = 0.00000032% Nutes
As you can see you are left with only a trace amount of origanal nutes.
The only problem I see is that you can not let your water stand for 24-48 hours. However this has never caused me any problems in my water region.
