Does any one have info on plant water uptake? Mine seems to be losing 10L ish a day. Planted out with lots of lettuce cabbage beans Asian greens celery herbs. 2.5 m2 of growing space

What is the weather like and how big is the system?

Some plants can really transpire a lot when they are trying to make the air more humid to make themselves more comfortable. Tomatoes can use up excessive amounts of water.

I don't have any exact numbers though but I generally hear my top up valves going off daily unless we get heavy rains.

Today was cool but sunny, maybe 20deg c. 700l gb 2.5ish m2 if gb surface area and a 1000l ft

so topping up 1% a day?

10 liters out of 1000

That isn't much.

I think I've heard that a single tomato plant can transpire almost that much all by it's lonesome per day if it's dry.

Ok cool thanks tcl I've noticed it using more water since I planted out the winter crop, about 3x more plant than the summer crop

So if you left your system for a week you would have lost 70L???? IMO you have a leak. I have put 50L in my 800L FT over nearly 2 months to keep it topped up, obviously I dont have your plant mass but seems unreasonable to me FB.

Hmm yeh that's what I thought but I can't fit the life of me find a leak
