Irrigation timers for high frequency fertigation

Been using these for 2-3 years.
They have no time setting for time of day so either on all the time or you can plug into your light timer run at lights on. I have had some running constantly for over a year like a cloner or aeroponics.
I keep waiting for one to fail. They just keep going. Haha
They do take a bit of wiring. Most I have I just wire a male and female plug and you can move it to whatever you want.
you can also put a momentary switch on it to cycle it with a press of a button.

I use this one
BN-LINK Short Period Repeat Cycle Intermittent Timer, Interval Timer - Day, Night, or 24 Hour Operation, Photocell Light Sensor Dusk to Dawn for Hydroponics Aquaponics Aeroponics https://a.co/d/341wY5q

Also a few of these https://inkbird.com/products/irs-wd1-smart-water-leak-sensor

@Inkbird makes a ton of cool gadgets and controllers

Thinking of adding a wifi outlet controller before the repeat timer so if I sense water on the floor and I'm not home I can at least disable the pump

Tip: Instead of using one NEARPOW timer, and constantly changing the watering timings/cycles throughout different plant stages or doing transplants, buy extra ones and program them for the different purposes instead. Then add labels so you know which one is which, and keep them LOCKED. Plug whatever one in you need at the time.

The only problems I ever had were constantly trying to change the settings to adapt to the plants increasing in size, and accidentally getting one timing off, etc.

That's a great idea. Those timers are cheap and they come two in a pack.
 
I'm gonna try putting one in the greenhouse this season, but probably use a nice waterproof box to keep it dry. Hope they hold up outside! :eek:

Run a web search for nearpow timer problems. I didn't find a single thread anywhere.. Not even this one? Plus, I been using them on and off for years and never had a problem. Work good enough for me ;)

Well I have a 60gal reservoir and 25gal drain reservoir, my new 3x3 veg tent thats almost setup easily overflows the 2 gal bucket with little giant condensate pump. 200gph so any hiccup Im screwed.

How many gallons do you think a 3x3’ water catch can hold, that comes with the tent thats like 4” tall? Depending on that is also a flood hazard. Great to hear though, this thread scared me.
 
I would probably stick the tent inside a kiddie pool or something to be safe, especially if I rented the place. I've never owned let alone flooded a tent with that much water, but i've had my fair share of hydro system floods. I also got a buddy that flooded the hell out of someones place a few years back, and had to repair all the flooring & sub panels. That's why I built fully water proof floors with drain plugs in my hydro rooms, in a trailer that sits outside. No more worries for me.

You should take your tent liner outside and fill it up. I'm kinda curious too. My guess is it would slowly leak out of the stitching, but might buy you a lot of time before it all leaks out. Maybe caulking the seams with flexible RV sealant would help.
 
I was just thinking that. Its why I use flexitanks over trash bins etc its build for it. I could down size main reservoir to 25 gal to match it and have one less worry.

I put my grows inside the hard plastic Botanicare pans. They have a pump so if I overflow I could in a pinch pump it right back to the res. I'd rather contaminate a res then drop my second story floor :lol: and a cheap pan and pump are some insurance

Thats a really good idea, Il probably do something similar. Ive been enjoying having a larger reservoir.

I am tight on space otherwise I would do something like that as a way to not rely on mechanics which can fail. I think I can somehow put the pump in bucket, in another bucket with pump like one said.

Or do you mean like a deflated one? Something fabric like but id have to hunt for specific sizing. The pumps I use have failed people before too, like anything else including fire hazard.

The original goal was to grow outside the house and should still be. This is all scary but likely could function fine but if it dont I might as well be done. Something I never thought through with dtw. Huge eye opener.
