I'm running a drip system for the first time, in 3 gal fabric pots. I'm at the end of my 1st week in Veg. I use to hand water in soil, therefore I was use to watering each plant with ether a full liter, or 1/2 gal depending on where I was in the cycle. I would get a good 20% run off. Now, I'm in Coco perlite 70/30 blend. I just set up the system and I'm winging it on how much water to water daily. Some people say water until you get a run off. Is this in fact true? Because that would mean I would set my timer to water for about 7 minutes. Right now I have my timer set for 2:45 and that gives me 250mls per watering. No run off. Think about how little 250mls are. I also have had some pretty seasoned growers say you don't need run off. OK so let's go with the "I don't need run off" Soooo, what is the amount of water in milliliters do I water daily at one time? I watered last night by hand and gave them 1/2 liter and still no run off. So how much is enough? If someone says water until you get run off, can you tell me roughly how much that is? 1/2 liter, full liter? Do I water to get run off daily? If that's the case 1 liter a day seems like a lot for young veg. Thank you for any help. Also has anyone used a Netafim drip system before? If so I'm using the stakes that you put into the coco.
