Hi Huel, I'm subbed up, don't know why I wasn't before... Hope you don't mind? I have a question in regards to DWC. I am currently growing in soil with Blumats for auto watering. I travel pretty regularly, but am always home on weekends. I liked what I read about not changing the res water and just feeding once per week and topping up once per week. Do you think it could go 5 days between top-offs? I'm a big believer in autopilot growing... maybe my notion that hydro requires the grower to hover over the plants twice a day is a misconception? I just re-read this whole thread, nice work man.
Thanks for the kind words, i'm glad you're following.
How long you can go between watering completely depends on the size or the rez, the size of the plant and the state of growth it's in. Big plants that are 4 weeks into flowering can drink up two gallons of water per day each, yet small plants early in veg might not even drink up a gallon of water in a whole week.
You should check your garden daily at least, if you can. You never know when pests or disease might attack, or when lights, fans, timers or pumps might fail. Does hydro require more attention than a soil garden, nope, that is in fact a misconception. Once you have a garden dialed in you should be able to go extended periods of time without needed maintenance assuming no unexpected problems arise.
