Tomato watering; water quantities?
 

I have rigged up a Heath Robinson style irrigation system in me
greenhouse; it is a collection of tubes and a water butt and a timer
and lots of pokey little bits of plastic and about 4million bits of
hozelock. It kind of works but in order to ehhh fine tune it (fine
tuning is a bit overstated; change that to: in order to avoid killing
all 20 tomato plants or flooding the entire housing estate), I wondered
if anyone had even rough guidelines as to how much water a tomato plant
needed per day in a greenhouse. It is delivered in a very slow dribble
to the base of each plant.

Half an inch (approx) over entire soil surface is what my patio-type
tiny plants are getting in the greenhouse,

So if you say 3-4 cm, multiply that by your soil area, and remember that
1000 cc is a litre, which is turn about 1/5 gallon, you'll get some sort
of starting estimate.

Seeing as yours is my only reply, I want to thank you for the effort
Kay but mixing metric and imperial measures is a disaster for
arithmetic :-).
The water gets delivered in a slow dribble to just one patch at each
plant. I need to know your area to do teh above? My areas do not
correspond to much (or have I got this back to front; entirely possible
I admit). I have been guessing at an average of a bit more than a
litre per plant per day.

Well, stay in metric, then, and measure your water in litres ;-)
You could do the whole thing in imperial, but the beauty of metric is that
it is easy to convert from solid to liquid volume.


Thanks Kay;
Metric is fine; gimme metric any day.
Ok will go measure and do lots of back of envelope calculations.

Anyone got any envelopes?

Use the total surface area of the soil, rather than the area of the patch
that you dribble on to.

correspond to much (or have I got this back to front; entirely possible

litre per plant per day.

That sounds reasonable - 1cm deep over the surface of a 6inch pot would
be around 660cc or 2/3l
