Did you know that you don’t have to grow your houseplants in dirt? Essentially the dirt is just the medium holding the plant up and allowing the roots to pull nutrients through moisture. You can throw out the dirt, and insects and disease along with it! Many houseplants grow very nicely in a water solution, and that is hydroculture for the home.
A bamboo stick in a pot of pebbles filled with water is hydroculture that everybody has seen. This lens will tell you how to apply this technique to all kinds of plants. It’s simple. It’s clean. And it works!
This lens explains hydroculture, helps you get started, and provides valuable resources.

What is hydroculture?
Its sometimes called passive hydroponics
In hydroculture, pebbles rather than dirt hold up the plant's stem and roots. The reservoir pot is filled to a pre-determined level with a water nutrient solution. The roots grow out around the pebbles. Once a plant is setup, you periodically re-fill the reservoir with nutrient solution.
Hydroculture is the little brother of hydroponics. In hydroponics, bigger containers, more involved water systems, and complex solutions are combined to grow vegetables that we buy in the supermarket. Houseplants will grow very nicely in a simpler, more passive version of the hydroponics process, which is called hydroculture.
5 big reasons to use water instead of dirt
and many small ones ...
Â·Reduce allergy; dirt holds spores, mold,mildew.
Â·Pest free - no soil born pests like dirt gnats.
Â·Easier clean up after spills. No dirt to sweep.
Â·Less risk of staining furniture.
3.Watering is easier
Â·Fertilize when you water, and less frequently.
Â·Over watering and under watering are eliminated.
4.Plants like it
Â·Nutrients are distributed evenly to the roots.
Â·Root aeration since pebbles do not compact like soil.
5.Less maintenance for you
Â·Pebbles don't have to be replaced and can be reused.
Â·Hydroculture plants have smaller root systems: less transplanting.
Â·Water less frequently. Your plants are fine while you are on vacation.
How hydroculture works
It's really simple!
Essentially pebbles hold up the plant and root system, which gets nutrients from a water mixture. Once a plant is setup, you periodically re-fill the reservoir with nutrient solution. Hence you are growing plants in water and without dirt. There are five components to a hydroculture plant.
The plant - many houseplants take nicely to the hydroculture process.
Pebbles - the plant sits in a pile of pebbles. For hydroculture we use clay-fired pebbles that come in several sizes, from pea size to grape size.
Inner pot - the pebbles sit in an inner pot that has slits for water access. The inner pot also has a slot for a water level indicator.
Water level indicator - a simple float tells you when the pot needs water (lowest level), and when you have enough liquid (upper level).
Outer pot - the inner pot sits in a decorative non-porous pot that is slightly larger.
How to get started
Make? Or buy?
I bought my first hydro plant from Interior Water Gardens in Surf City, New Jersey. Also bought a kit from them and immediately did my first transplant from dirt to water.
It's a personal choice. You can enjoy hydroculture houseplants without every playing in the dirt. Hydroculture Resource Links are provided below for some excellent sources. You can also convert your own plants and enjoy the process. Transplanting tips are provided below.
The easiest way to grow your own is to root plant cuttings in water, and then plant them in a hydro pot.
5 Steps to transplanting
Moving from dirt to water in 5 easy steps
Preparation - gather all materials at the kitchen sink: plant, pebbles (rinsed), inner pot with water level indicator, outer pot.
Remove the plant from its dirt pot. A dry plant is a better starting point. Hold the plant at the base near the dirt and gently wiggle it out, dirt and all. Tapping the pot might help free the plant.
Remove the dirt form the plant. Knock off loose dirt clumps. Hold under gently running, room temperature tap water to rinse of the remainder of the dirt. Touching roots is ok, but gently please. Trim off dead or extra roots.
Plant the plant. Cover the bottom of the inner pot with pebbles, about an inch. Place the plant on the pebbles, and spread out roots. Hold in place with one hand while pouring more pebbles around the plant roots up to the base. Tap the container to settle the pebbles, and then rinse under room temperature running tap water.
Finish and feed the plant. Place the inner container in the outer container, and fill the pot with nutrient solution until the water level indicator shows its full enough.
These are places I've browsed and shopped. If you are tempted to get into hydroculture by this lens, looking at some of these sites should move you into the shopping cart stage.
- Interior Water Gardens
A hydroculture store on the Jersey shore. They specialize in Orchids, which are great water plants! They sell kits and offer advice.

got a couple of minutes for a musical interlude (about houseplants!)? - really, it is (brief and about houseplants) ...
Did you ever wonder if your houseplants have feelings. This clip was produced and directed by two 14 year olds from Idaho, home of Napoleon Dynamite. The music explores a noble experiment. You be the judge.

I gave a friend of mine some Philodendron cuttings about 7 years ago and she still has them in water.
anonymous on March 18, 2012:
That is really great. i'm glad to have opened your lens. it opened my mind to try it. i once gathered stalks/stems of a vegetable in a water filled container for ground planting but after several days, it rooted and started to grow leaves, i was fascinated and just kept watering it, the plant grew nice until i went on a vacation and the plant dried out because of no water. now i have the techniques on how to make it right. thanks a lot.
anonymous on November 04, 2011:
Nice lens! Keep up the great work!
One squid thumbs up vote left for this lens!
baumchen on November 03, 2011:
Its really important that the pebbles are not too big, is what I have found out. Only mature plants can deal with big pebbles (>10 mm).
homerepellent on October 08, 2011:
A complete guide from transplanting, to starting out from scratch, to maintenance. A thoroughly great lens to begin your journey on hydro-plantation. Thank you for the information.

Michelle77 LM on August 15, 2011:
This is very interesting but doesn't it take more work to change the water in these kind of plants than to just water them? I tend to forget to change the water until it starts to get slimy and stinky :( OOPS!
carredsal on August 05, 2011:
Very interesting...I had no idea you could use this method for house plants...
AllyVuitton on July 28, 2011:
I'd never heard of this, so thanks for the eye-opener. It's a pretty neat idea, and hopefully gets rid of all the mold! I'll definitely try it.

Did you know that you can bless water - since 1999 Dr. Masaru Emoto has published several volumes of a work on how words and music influence water - etitled "Messages from Water", it contains photographs of water crystals next to essays and "words of intent".
fulltimehockeymom on May 23, 2011:
Just setup a hydroponic system myself and I have to say I am loving it. Followed some hydroponic system instructions and started growing my own herbs from a small unit in my kitchen. Nothing like using fresh ingredients to give your dinner a yummy kick.

A really interesting Lens! I would love to try hydroculture, but always mistrust the feed. If I could buy something organic, then I would have a go, certainly much leaner than soil!

Hello there! I feel awesome today, and I would like that you know that it happened due to such an unexpected affair, which drove me so high! I didn't thought that this could be for real. However, now, I have already experienced it by myself. What I wanted to mean is that this stuff called Viagra Prescription , Generic Viagra and also Viagra Online won't ever let you down when you need some action. Look, I apologize If this offended somebody. Anyway, in a nutshell, I am glad to be part of this fabulous site. By the way, this lens is dynamite!
waterbeads on September 15, 2010:
WaterBeads4Plants has been used for bamboo a lot, and it's good to see my experiments with other plants should do fine. Great way to add color and water at the same time.
tssfacts on September 13, 2010:
I have always wanted to do this. You gave me enough information that I think this is doable for me to at least try.
Tarra99 on September 09, 2010:
I did not know so many plants could grow in just water...the only one I was aware of was the lucky bamboo. thanks for teaching me something new

mpp1 on August 24, 2009:
I have a blog on hydroponics and I found this a really interesting aspect of passive hydroponics. The lens is well set out and captures the attention - you obviously are well into this field of hydroponics.
Keep on developing the lens - I will certainly come back again.

Hi Cave I use the Mittleider method "The poor mans hydroponics" I agree 100% you can grow anything in water or a clean filler, we use ground up pine needls and sand. Check out the Nutrient mix, I haven't done any pure water growing yet but it will be fun to experiment. www.Foodforeveryone.org
anonymous on April 03, 2007:
are you sure the root system is smaller in hydroculture? i have more roots growing into the water reservoir than in the entire root ball of ordinary soil-less mediums in my experience when i compare the root systems of equally sized plants with different substrates, the hydroculture is always larger

I watched in horror as my cat turned my little therapy garden into his personal litter box! :( Can this method be used inside for eatable plants such as cherry tomatoes, green onions, and spinach? Are the nutrients needed organic?
MB on August 28, 2006:
I had never heard of lenses prior to my attempt to research raising house plants in water. I googled Hydroponics and was mired in too much info about how to farm without dirt. What I really wanted to know was all here in this lens. Thanks for this well written lens. The help was much appreciated

Jennifer Einstein from New York City on June 24, 2006:
I can't say that I am going to start using the water system, but I enjoyed learning about it and will absolutely consider it in the future. Not worrying about over/under watering sounds really tempting! Thanks for being the new something I learned today!
