Angela,

Could you please provide some tips how long to run my drip for vegies garden at this time of heat. My drip tubing have emitters every six inches and can water at rate of about 0.5 gpm. So how many minutes should I run this setup. Thank you for your advice. Brian

I wish there was one answer I could give you. Run your system long enough to wet the root zone of your plants to encourage the roots to grow deeply. Run the system and observe how long it takes to do this. Run the system for that amount of time each time you water. During the hottest times of year (especially when there is very low humidity) you may need to run the system every day. Water in the morning.
