Anyone using automatic watering systems for their greenhouses? I only know
of a "hydromat" and Juliana has invented sort of a drip system, with long
tubes you put everywhere in your greenhouse.

But can't you just put a big barrel of water in your greenhouse, and rely on
evaporation-humidity to do the job?

Presumably you have ventilation in your greenhouse? The answer to your
Question should be self explanatory.

Don't bother with branded systems such as Gardena/Hozelock etc. The
retail markup is outrageous and they aren't of such great quality... get
a decent one from somewhere like NA Kays or LBS Group or LS Systems.

Even Wickes do a self watering kit for between 20 & 50 quid.

Timers/programers range from about 15 - 40 quid.. Rainbird are good.

Capillary matting is good and IIRC the Hydromat system comes with a
diagram to make a DIY self filling reservoir with a piece of guttering
and an inverted reserve container.

Be wary of your water supply. Physical dirt will clog systems, bacterial
& fungal contamination will affect your plants and possibky your
health.. THis is where the pro's and cons of storing water *in* your
greenhouse come in. Some people do it to increase humidity, others say
*never under any circumstances*
