Mix your fertilizer in a large container. I mix 5-10 gallons at a time for orchids. I mix in a 32 gallon plastic trash barrel for plants in pots outside.

What is your grow space Clawhammer? Curious, and you’ve probably said, but I don’t remember...

I grow in a 15' x 15' room in my basement. I recently plumbed in the drainage so skipping the fert mix is the next step in making my life easier

Do you use RO or tap water? Either way, why don't you just water from a large reservoir if you're set up for drainage?

I use tap, our water here in Portland is lower TDS out of the tap than my water was back in Ohio after RO (27 ppm).

I have a hose running into my grow room and that's what I want to use to water because that is the easiest and most effective.

Question though, how are you suggesting getting the water from the res to my plants? Is there some kind of sprayer that I can use directly from a res, maybe with a pump that goes into the res? I have a large rain barrel that would be perfect as a res.

Yup, that's the reason I was asking. I was using a 75 gallon rain barrel before I moved my grow space. Now I have a 70 gallon tote. Let me take some pictures, and I'll get back with ya later today.

Okeydoke. Here's the 70 gallon tote. I'm using it now, as I can fit it under the first shelf at bottom of window height.

The RO runs off the sink, direct into the reservoir. You could just fill the reservoir with a hose instead. Note it's reinforced with threaded rod and a board. That's to avoid the bulge effect. On the right side, you see a black no-kink hose. It's connected to a submergible pond pump. Didn't take a picture of the pump, because it's way bigger than you need. It's one I already had and has a ball valve on it to dial it down. No one really needs a 2000 gallon per hour pump to water orchids. :rofl: One end of that hose connects to the pump, the other end is just hose, and what I water with.

The pump is plugged into a remote plug. It's the little rectangular box you see right below the retractable cord reel and it's plugged into one of the reel outlets. There's a hand-held remote with it, and you program for each plug so you can water and turn the pump on/off as you need while watering. It's hard to see, so at the bottom I'll put the info on it from Amazon, where I bought it.

I'm in process of hooking up a MistKing to the reservoir to auto-mist a few select plants, and there's a pond mist fogger floating in there that I use instead of humidifier. So the reservoir serves four purposes: water, fertilizer, auto-mist, humidifier.

WaterWitchin: Thank you so much for taking the time to post this! I actually have all the needed equipment from my discus fish keeping days.

A couple questions:
* Does the fertilizer water in the res get funky over time?
* Is running a humidifier with fertilizer water pose any danger?

By the way that pond mist/fogger you just posted is the answer to my humidifier filling woes!

I use that amount of water weekly at least, so I wouldn't know. Just don't put more water in the reservoir than you plan on using in a few weeks or a month. I used to mix Klite into a gallon jug as a concentrate to use over time, and it never got nasty.

I wouldn't know if it's a danger... I'm not dead yet. :biggrin:

I used to use a separate tank for the mister/fogger, a 20 long aquarium, and a 25 gallon tote for the MistKing, no fertilizer added of course. I'm just using the same reservoir for all as a space saving option.

The fogger probably won't last quite as long, but they're cheap. ($10-12) and you can clean them a time or two before they go belly up. Make sure you get a float for it as well. Here's links to them...

The float, of course, is used over and over. When I had it in my basement and it was a large open area I just two of them. Kept the humidity really crankin'

And no problem with the details... that's what we're all here for. Learn, ask, teach.

There are a several ways to do that.

Cheapest: In a 15' x 15' room, you only need about a 25' hose. Just put the Dramm Siphonject in between the "supply" hose coming in and the 25' "irrigation" hose inside.

More reliable: Use an injector pump instead of the venturi device.

Most flexible: Fill the reservoir tank (in which you can mix chemicals) with the hose, use a pump with integral pressure switch to pump the water through your irrigation hose.
