How are the veggies coming along?

Nope, you'd end up with too much capillitating! All the water would flow out of the reservoir and flood the tray. Capillary action rather than gravity is the name of the game. The idea is that having the reservoirs below keeps the mats on the tray, (and hence pots), moist at all times, but not waterlogged. It also keeps things humid, normally good in a greenhouse.

Well I suppose so, but if the current problem is not enough capillarisation, surely a little less gravity would help? Could you reach a happy medium... maybe try equi-level with the waterees?

Gravity homeopathy. Set the water even lower.

Yep. My speculation is that the troughs are too low. I read somewhere that that matting has a lift capacity of 6", I think I've got more than that height difference. I can't be arsed to sort it now as not going to be away for any length of time this summer now.

Unacceptable. Put all other business on hold until you've achieved optimum elevation. I demand a resolution.

I wonder if the pores in your matting have relaxed over time and become less effective

I know exactly how they feel.

Ummm, that is a very good suggestion, I do believe you make be right. Something has definitely changed from last year.

Could the pores be going getting bunged up over time and just need a blast with a hose? (disclaimer of course in case you do that, damage it and blame me)
