Hydroponics is the process of growing plants in sand, gravel, perlite, hydroton, or liquid, with added nutrients but without soil.


The Hydroponics Reddit

Hydroponics - a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to byproduct from fish waste, duck manure, or normal nutrients.

Marigold and chamomile! Sprouting!

I'm pretty new to hydroponics and growing in general. Got gifted a nice big hydroponic growing system and got some marigold and chamomile seeds from a local seed bank through the mail. After 3 days of wondering if my plants will be okay together, it seems they're just fine!! I've got chamomile here and there in the system sprouting up and looking really healthy, as well as a couple marigold that I honestly did not think were going to sprout that did indeed and strongly at that! Never would've expected it to only take a few days for it to work. I'm mighty glad it did though. For my first time ever, I'm supremely satisfied even if they don't fully blossom for a while, which I assume they won't as they're supposed to take 7-10 weeks for the chamomile and if I remember right even longer for the dwarf marigold. Happy planting!!

Put some shiny on it!

I'm proud of the hydroponic gardening I do. Its awesome. I love showing it off to friends and I don't want to hide it in the back of my closet.

I'm looking to implement the Kratky method or other methods of hydroponic gardening in a way that looks stylish. I don't want a blank white 5-gallon bucket in my living room or a home depot bin.

I do small hydroponic starts with /r/aerogarden and sprouts. I'm getting prepared to scale. I'm a remote software engineer and I want to make my hydroponic garden my background during zoom calls.

What's your best way to make your setup look cool?

Trimming tomatoes

So this is the first time I've really tried trimming tomatoes and I think I got a bit out of control. Normally outside in the garden I just let it go. Did I over do it?

Living arch project

Hi folks,

I'm building a living arch with a target presentation date in 100 days (3 months). My plan is to place planters on either side of an archway, put 5g dwc buckets in planters and cover with soil or similar. For plants I was thinking morning glory and sweet peas 2x per bucket.

The idea being the DWC will enable very quick growth while this setup will appear to be traditional. Though, I am stuck if it will really offer that much of a performance boost or if I should just get well established starts and drip feed them.

Not married to the plants either. Any feedback or suggestions to this idea?

Noob here. Just got my first EC meter. My gauge says 1920. My fertilizer recommends single digits, like 1.2. What units are these? Does 1920 = 1.9 EC?

Should I pull one of these out? (Lettuce)

Just wondering if it's necessary to only have one seed going at a time? Will they get too crowded and not grow to their full potential?

Should I let the drip go at max level or will that water board them?

I just switched from the grey buckets to the black buckets because roots have taken off and are hard to remove from old system for cleaning. I’m not sure where to set the drip levels. Thankful for all the help!

2.5inch PVC pipe system.

What is something fun to plant in an indoor PVC system besides strawberries? I edited this because I realized it was too vague before

Hydroponic nutrients.

Hi All,

Relatively new to hydroponics, with the exception of a highschool science project.

I've learned that you can't use regular fertilizer for plants in soil, because the bacteria in the soil is expected to break down the nutrients so that the plant can absorb them.

Is there a way to extract of flush out the nutrients out of soil and put them in a hydroponic system? Or is there some setup I can put together to.... brew (??) the nutrients for the hydropoic system starting with regular fertilizer?

What EC and PH works best for your crop?

Just curious what people are running. Post the following:

  • what is your crop?
  • what EC range have you found to work best?
  • what ph?

I’ll start. I grow ornamental tropical plants. EC 1.5 and PH 6.

Suggestions for fast growing & flowering plants in a classroom?

For Earth Day I've been tasked with growing flowering plants (they specifically requested flowers) in a Tower Garden hydroponic set up. It's for elementary/middle school children, so the plants would preferably be as fast growing as possible, because the kids lose interest in things quickly.

I realize this is a lot to ask, but does anyone have any suggestions? Thank you!

Nutrient/ph delivery system

I'm working on a automated resevior dwc style garden. Currently only doing DWC in 5 gallon buckets and am tired of filling each one every other day and measuring the ph amd ppm Constantly. I have everything for to build my set up with pumps and my resevior Yada Yada. Only thing I'm struggling on how to set up is a nutrient and ph feed system to the reseivor. Particularly having the bottles elevated and using ball valves with .17 tubing connected to the bottles that feed into the resevior.

Does anyone have a homemade set up they created that prevents leakage? I've tried drilling caps into bottles and sealing the hole with the feed tube inside but I can't seem to get a perfect seal. I can't find caps with a nozzle pointy enough to fit snuggly either.

If anyone has a set up or know of an option please enlighten me.

Dilute fertilizer from the garden

Hey guys,

I was wondering if I can dilute fertilizer I have for the garden to make use of it for my self-made system. I calculated a bit to get to somehow the same concentration.

Starting my self made set-up

Yesterday I started with my self-made setup. Lighting is a moveable two in one lamp.

I am not planning to pump any water. This is really needed? I was thinking about to place an air pump. Could this be sufficient?

Any feedback is welcome.
