How to water a greenhouse without hooking up to the mains permanently.
I have a brick based 8ft by 15ft greenhouse which is some way away from the mains water supply. It is planted only with tender plants and is heated to 55 degrees, 365 days a year. I want to install a trickle watering system which means that I do not need to keep connecting the mains water hose to the greenhouse twice a week, especially difficult in the winter. I have looked at camping water reservoirs but am not quite sure whether the water pressure would be sufficient enough to force water through the irrigation hose. Any suggestions would be much appreciated. Many thanks - Miranda

It depends partly on the pressure requirements of the emitters--that will tell you how many cm above the highest emitter the bottom of the tank needs to be. You will also need to determine approximately how many gallons you use per watering, to determine how big a tank you will need, to get the refill frequency you can stand! : )

hubby but a T junction into the pipe work and I ran a hose across to the grenhouse fro that. I buried it under the soil in some plastic down pipe to help prevent it freezing in the winter. I also have it on a battery operated timer system.
hope this helps.
