I rembember that one of the member's systems was running a grow-bed that was continually flooded. Who was that and how is that going?

Edit: I think people will have no idea what I am talking about here. Somebody had a gravel filled grow-bed that always had water in it at a constant level (ie flooded) with continuous replenishment via a continuos inflow and outflow of water. I had something similar going by accident when I had my small gorw-bed, in that the drain had clogged with roots meaning that it would only drained as quickly as the inflow once the water got to a high level in the bed (the height of the water forcing the water to flow more quickly). My toms grew fine through that period - I used to liken it to DWC wtih gravel. The roots would have been water roots - yet they had the support of the gravel.

do you mean that it was filling and draining at the same speed? usning a standpipe to stop overflowing? Doesn't ring a bell, but am interested to see if it does for anyone else

This is pretty much what the other person was doing (I on the onterh had was drainign from the bottom - something you would not try to replicate). I am embarrassed I cannot remember who it was - a regular I think. Remember they had two beds - one was continuous flow and one was continuously flooded - the second seemed to be doing a little better.

I was gonna nominate Murray but he gets picked on too often with his fish (no it wasn't Murry and I don't recall anything on it either)

i recall the picture but cannot think of who it was. I have a rec`ollection of it being a foreigner

I have a recollection of me telling them it would not work very well because of lack of DO and no doubt other things. Then of course I did it accidentally (this was months back) and it seemed to be fine - for the short time I had it that way.

TimC in Perth? I'm fairly sure its someone in Perth

here it is

Where are pics of TimC's system?

Well done Jaymie - that's what I was looking for. It is TimC. Timbo - how is the continuously flooded, continuous flow system going?

good memory Jaymie!

every now and then the brain kicks in and actually works

My pond has been running like that for years (by design!). I have only ever put water hyacinth in it, though. I added a schematic to that thread for clarity.

VB... It was going OK... decided there was not enough sun, plus the top pond had a leak so I have it turned off atm. I had no issues with it so far. I am moving it to a better loaction onece the shed is finished so I can get a better idea then.. The lettuces never formed a 'ball' but they had significantly more growth over the f&d.

my lettuces are not forming heads either. I am pretty sure lack of light is the problem
