Resevoir for DTW, 6 feet below pots. Is a major pump needed?

Hey guys, I am building a plan for a new indoor setup that the wife finally approved. It will be a 4x4x6.5' drain to waste setup in an existing closet (giving up my own closet, Im commited lol), top feeding using drippers.

The closet happens to be overtop of my small basement crawlspace. My plan is to keep the resevoir container in this space as there is a water tap/hose within arms reach, aswell as this area is much cooler so water temps could be kept low. There is also my sump pump / sump well so I can easily run my wastewater to this as well as dump the res if I need to. No heavy lifting YAY!

But all that comes at a price of having the resevoir on the level below the grow space, which would be about a 6 foot lift from the resevoir pump to the drippers. My concern is that I need to buy something like a waterfall pump rated for lift, but Im not sure if they could ever be dialed down to a slow drip, or if a larger size hydro style pump would be fine and well? I think my biggest is about 400lph

Any experience keeping the res at on a lower level below the grow space? I can put it in the grow space if I have to, but would take up valueable space and being as Ive never grown hydro or used a res before Im not sure how water temps would be affected. My initial thought is because Im using a cycle timer and something like 20 second cycles every 3-4hours the pump wouldnt affect the water temp, but the lights and ambient summer temp in the room would.

Just to get an idea take a glance at my stuff.
Different type of grow!
Our spaces are the same 4x4x6'7|, I am running drip, DTW.
Difference is my rez is about 40" above my plants, but you can get a small pond pump. I am running an ECO 1056 and it has a max head of 9', GPH 1083. I am running 5 plants, coco, in 2 gal SmartPots, 3 - 2 gph pressure comp. nozzles per pot, so 15 in all, I started with 4 gal that's when I bought the pump because the smaller pump I had did not seem to do the job, so now I have plenty of pump.
Got questions! Just ask.

The water will be very heavy above the pump. It's called head pressure. You'll have no problem using whatever pump you need for the right flow rate. Such a cool idea. Hope you show some pics of this. Wish I had a 6ft deep res with 6ft ceiling height too.

I tried a fountain 600lph pump that I had and it only can raise the water 43", using a 3/8" feed line.


I hooked up my 1/6hp sump pump and a couple fittings to bottleneck the outlet to 3/8" hose and it shot the water out of the hose higher than I could hold it, atleast 8 feet high. So I guess a dedicated sump pump is what my setup will dictate for my future setup

Sump pumps are meant to go on and off. I don't know about continuous usage. I used a heavy duty pond pump to service my 16 station, 2 tier veg room without a problem. It had plenty of flow push 4' up, I am sure it could have handled 6'. I believe it was a 1200gph. Got it from pet mountain.

Also, had a 2400gph for my flower setup. Both worked continuously without issue 24/7.

Low Pressure Pumps state how high they can push water through X diameter tubing. Instead of drippers, simplify to a flood and drain. No need to DTW as long as nutrient is changed out 7-10 days during flower

Why would the pumps be running 24/7? I only plan on running them 30ish seconds 4 times a day
Do you know roughly how many ounces of feed you're giving in the 30 seconds? just curious to compare against my autofeed

I'm running mine with 100gph pump to six pots, takes 2 minutes to feed about 16 ounces to each of my .7 gallon pots, twice per day

I will be "flow controlling" them with ball valves. I will try to adust them to feed 2 gallon pots with slight runoff. Will take some tweaking.

I know from hand waterring I get runoff with about 750ml/plant. So id imagine i will be in that ballpark
