Ebb and flow (also known as 'flood and drain') is a simple hydroponic growing method that's cheap and easy to set-up and relatively hassle-free to maintain. Growers enjoy bigger yields over hand-watering and are freed up from the chore of daily manual irrigation. We explain everything you need to know about ebb and flow in under six minutes - check this out!

I like to have circulation in my flood bed. One big advantage of Ebb and Flow systems, which wasn't touched on in this vid is salt removal. With some kind of circulation not only do your plant get extra oxygenated water, but more effective salt removal. So I've come accustomed to nice, deep floods. I think a mechanical timer is fine if your using a circulation jet, or forced bubble jet imho. Examples in my vids. Very easy mod.

[@StrangeStories12]

Yes salt removal was mentioned here actually

[@GMT439]

15 minute feeding does work. I've seen it done. Pot size and plant size come into that equation as does the power setting on the feed pump. EG: If you run the pump at half power than it will take twice as long to pump the nutrient and the plants will receive roughly the same amount as they would running for 7 minutes at full power pump pressure. As long as the plants have drained fully and the gap before the next feed is long enough it will work. It's not ideal but I have seen it done and I know it works.

I have grown in hydroton before and am going to do it again. This time however I got a tip from someone saying to just fill the whole tray with hydroton and plant your clones directly into it. It will develop a much better root system than even with baskets. Plus its reusable and we try to stay as green as possible. I love Hydroton.

[@Just4Growers]

+Ted Dekens Yes Ted, I couldn't agree more. I love hydroton. It's particularly good for plants which enjoy good drainage and a well-oxygenated root zone thanks to all those tiny little gaps between the spheres of clay. I've tried the "filling the whole tray" method and it works great! Uses a hell of a lot of hydration, for sure, but-as you note-it can be easily sterilized and re-used. (Something I'll be sure to make a video about at some point!) Another downside, of course, is that your plants can't be easily moved so it takes some skill and precision to dial in plant numbers and vegetative periods so that you get a nice full, even but not jungle-like / overly-competitive canopy. As for the plus sides, well you already know them! All that hydroton is like a luxury crib for your plants' roots! They are not bound by pot size any more! How often do you find you flood the table when your plants are mature? Once every 30 minutes, or every hour, or less? My one main tip with running a system like this is to air-prune your plants' roots in propagation stage so they are literally like race horses busting to get our of the starter gates! Roots everywhere coming out of the net pots or starter blocks, whichever you use. Anyway, thanks for stopping by-hope you're subscribed!

[@ThatGamerDude9000]

From my experience, 15 minute flooding isn't too long. I had the eco100 for a 7 gal system with hydroton pebbles, flooded my roots 3 times per day (4 times when plants got bigger) for 20 minutes each flood, and they grew just fine. The exact timing of lights and feeds aren't that important either. If you think about it, in nature, when it rains, it is usually cloudy, and can be for several hours as it rains. Sure, the plants have sun exposure after the rain when the ground is still wet, but plants can grow with multiple consecutive rainy days with significantly reduced light. It can also rain at night. Maybe it's optimal to time floods with light, but far from necessary. I haven't tried timing my floods with lights, but I would think timing it shows diminishing returns. The key for hydroponics is having the nutrients readily dissolved in water, rather than have it be in the soil and waiting for rain.

[@OffGridInvestor]

I thought the same. I have seen plants be propagated, even tomatoes being left in water for 2 weeks. Those roots don't rot. What's an extra 10 minutes or more. Especially when you look at kratky systems

[@jagababa]

I started with a deep water culture, as it is even simplier in setup. I've had the biggest yields i've ever seen! But there are some parameters that you need to watch carefully. 1. humidity (provoked mold/fungus) 2. ec and 3. ph that becomes quite unstable the bigger your plants are and the more they suck.

[@Just4Growers]

@@StrangeStories12 Good question! I haven't had much success with tomatoes in water culture-the skins tend to split. I later found out that I had selected the variety badly. It runs out that there are several tomato varieties that are known to perform well in DWC, including: Cherry Tomatoes: Sweetheart, Sun Gold, Black Cherry These varieties are small, sweet, and tend to have a good resistance to cracking. Beefsteak Tomatoes: Big Beef, Beefmaster These varieties are large and have a good flavor profile, and are known for their crack resistance when grown under controlled conditions. Cluster Tomatoes: Trust, Tradiro These varieties are bred for commercial hydroponic production and have good resistance to many common tomato ailments, including skin splitting. Roma Tomatoes: Mariana, Plum Crimson These varieties are known for their firm flesh and are less prone to cracking compared to other varieties. Hope this helps! Good luck :)))

Thank you Chand. All you really need for an ebb and flow tray is some kind of plastic tray with 15 cm high sides.

[@Just4Growers]

+Faheed Alajmi Outdoors? Yes. Depends on what you want to grow. Season is key with your climate. Your mild winter would be a great time for leafy greens, lettuce, cilantro etc. Your summer's get very hot - so I'd recommend going BIG on reservoir and think about how you're going to try and keep it cool and well aerated. If you can keep their roots nice and cool you'll win. Try fabric pots with 70/30 coco/perlite mix. Just base nutrients. Keep it simple. Indoors: yes, you'll probably need an evaporative cooler if it's always 6% humidity in El Paso like the weather says today! I thought my neck of the woods was arid! Happy to learn more about your plans Faheed. Peace and happy growing, Everest.

Hi! So I'm currently setting up an ebb and flow system with actually the same tray you're using here. I see that you're using one of the deeper wells for the inlet, and the other diagonally across for the overflow, is there an advantage to this positioning compared to both fittings being in the same well?

so..... I really want to fully crack the "ebb and gro" controller, but, in the mean time until I can find some actually fruitful info on it, this may be a more practical rout. so would a float switch to shut the pump off when overflow level is reached be an effective means to control the flood and drain? a digital timer may be a bit difficult to obtain, but I can probably get those rinky dink dial style. anyways, this was worth a sub to me, so you got another follower bud

Ankit Singh Clay pebbles are dirty and don’t provide much air to the root zone other than in between the balls. Coco peat often comes with free fungus gnats and should really be amended with 30% perlite - plus it holds on to calcium for dear life.

1. Good video. 2. Does ebb & flow work outside hydroponics? For instance would growing seedlings in potting mix benefit from an ebb & flow schedule?

[@Just4Growers]

Karl Fimm Hi Karl. Great question-thank you for asking. YES, you certainly can use ebb and flow for seedlings and mature plants grown in soil / peat based potting mixes. As well as giving you some of your life back, this method also allows you to use organic nutrients if you wish-especially the types which are more prone to clogging drippers. I would recommend a nice light potting mix with plenty of perlite or vermiculite. I would also choose fabric, breathable containers or root trapping plastic containers for increased aeration. Yes, these types of containers oblige you to irrigate more often, but that's hardly an issue when you've automated the process! :) Incidentally, I am in the process of making an ebb and flow propagation tray right now! Once I have it dialled in I'll summarize it all in a video. Thanks again for your question and please consider subbing the channel. Peace and happy growing, Everest.

[@Just4Growers]

Karl Fimm PS You can find my outdoor modular ebb and flow experiment on my channel. I live in an area that receives very little rain, especially during the summer months.

[@Just4Growers]

+PowerGrow Systems Thanks for your question amigo. The primarily reason we irrigate our plants is to supply water. Around 95% of this water simply flows through the plant (from root to stomata) - released back into the air as water vapor. The latent heat of evaporation (as the water leaves the stomata as vapor) is what helps to keep the plant cool. At night there is no solar radiation or grow light radiation - by definition! So there is not such a pressing need to keep the plant cool. A drier root zone also helps keep oxygen more abundant which is used (during the day and night) to fuel cell growth and other metabolic processes including plant the reformation of the enzyme Ribulose-1,5-bisphosphate ( C5H12O11P2 ) in readiness to form RuBisCO - an enzyme used to capture atmospheric CO2 once the lights come on again / the sun comes up. PS I visited your website's education / tutorial section and didn't find a link to this channel or any embedded videos! Just sayin' .... you're very much encouraged to refer to them on your website.

It depends on what kind of plants you want to put in your system. Some plants need more water and longer and some must be shorter. I am allowing 10 minutes to run the system with the intervals of 10 minutes. Now I am using 4 pots so filling with water takes longer and still set to 10/10

I also saw on your video that the "drain process" helps to "push" fresh air to the roots zone.

conentrated hydrogen peroxide, H2O2 (liquid oxygen), I use 32%. It's safe for the plant and breaks down into water in a few days naturally. Just use gloves and wear safety glasses.

[@RicckybLymuel]

I'm new and my system is hella confusing..I have each drain and pump for water but when it gets to drain it only goes so far..is this normal?is have to drain the rest?

[@stephaniebrace7248]

Adjust the height of your drain. It should drain out all by itself. Another tip is to make certain that the water drains towards it. you can add shims to one side if needed.

[@JesseLebel]

So the they don’t receive any water at night?

[@Just4Growers]

That's right. Typically no irrigations after it gets to one hour before lights out. Also, good to wait 30 to 60 mins after lights on before first irrigation.

[@NoMoreMrNiceGuy223]

There is a ebb and flow vs top feed drip on a controlled test... The top feed drip system yielded 1/3 more fruit

[@Hyccups]

Hey there! Super cool video with lots of information. I'd like to learn to which tank you connect your bluelab guardian probe to? Do you have one big tank for collecting the water or several? In this case do you use more than one probe? Thanks so much :)

hi i have ebb& flow system with rockwood , please help me how many time can i flood my system a day eacht time with 15 minutes..?

[@Just4Growers]

+Minh Tran quang So many factors involved Minh, but you should try to determine when your rockwool is 50% dry (50% of its saturated wet weight) and re-irrigate then.

[@felixhunger7000]

How long should my roots soak in the solution?

[@Just4Growers]

+Felix Hunger as short a time as possible. Don't flood for any longer than you need to.

[@felixhunger7000]

Well, that is fine but you never really answered the question. Just long enough for them to get wet? about 2 hours? I do mine equal amount of times through out the day. 4 cycles total all even spaced same about of wet and dry time. I'm finely getting my A. Gold to bloom nice and smells great as well as my Columbian Gold.

[@harmonica1cat]

How good would grow bags work in an tray flow & ebb system work ?

[@Just4Growers]

Harp Cat They would work great. Just be sure to use a filters and time your irrigations appropriately to the media / plant development so it doesn't get oversaturated.

[@a.c.3015]

Everest Fernandez how about grow bags with fox farm " happy Frog" with 30% perlite? 2 - 6 minute floods? Flowering canna plants.

[@Just4Growers]

30% perlite sounds good. Keep the flood times as short as you can.

[@Just4Growers]

Yes, keep the floods on the shorter side.

[@non-compliant5431]

Nice setup

[@Umadcuzubadbrah]

hi, do you know any european online shops that deliver these trays? all i can find is USA shippers and the cost of shipping cost is insane…

[@Just4Growers]

madcuzbad. brah The trays are Duralastics, manufactured by Botanicare. My suggestion is to contact a very helpful guy called Bruno at Multigardens in Spain. He speaks Czech, English, Spanish and Portuguese. [e-mail] Tel: [phone] . I'm sure you have lots of options but I understand he has a direct hook up with importers and I'm sure he can, at the very least, steer you in the right direction. Peace.

[@Umadcuzubadbrah]

Everest Fernandez thank you ;) i wouldn't ask this without doing my own research but I'm totally not at home in the hydroponics hobby. i plan on using this to grow aquacultured corals to sell for the aquarium hobby, which these trays are perfect for.

[@Just4Growers]

madcuzbad. brah Hey Madcuzbad-I got in touch with the importer the other day (as I need a 4 x 4 tray myself!) and they told me that they didn't have any in stock, currently, but were expecting some on the next container from the US. I'll let you know if I hear it's landed! :)

[@billmelater4081]

Great video! Thanks for sharing with us.

[@JaySyzdek]

Quality video. Thank you.

[@ukgorillagrowbudman7194]

how do you clean the clay pebbles for reuse

[@Just4Growers]

ukgorillagrow Budman Thanks for your question UKGGB! In a large container I mix 20L water + 200ml hydrogen peroxide (35% food grade). I add as many clay pebbles to the mix so that all are submerged. Stir / agitate / leave for 10 - 15 minutes. Obviously take care when using H202. Happy growing.

[@smaharaj180]

Live in europe, some of these supplies are hard to find, any advice?

[@Just4Growers]

+Sean Maharaj which country are you in and are you interested in anything specific?

[@smaharaj180]

Ireland, I'm new to hydroponics so bear with me. I've found some of the products listed since I posted like the stand www.bghydro.com/hydroponics/plastic-grow-trays/fast-fit-tray-stand-2-ft-x-4-ft.html, pots and trays thehydroponicsstore.ie Generalhydroponics sunlightsupply and fastfit don't have stores in europe. Amazon does not seem to provide much in terms of hydroponics. I'm interested in everything else I have not found on the list. Could you recommend useful retailers, shippers or anybody that sells hydroponics to/in europe as cheap as possible? In any case the eco 100 pump, resevoir and nutrients are of specific interest to me. Thanks for the fast reply.

[@Just4Growers]

+Sean Maharaj I suggest checking out General Hydroponics Europe (GHE eurohydro.con) and ask their advice on pumps too. They are very cool people and have always been super helpful as well as a great source of knowledge.

[@smaharaj180]

+Everest Fernandez (Just4Growers) thanks for the help

[@DaneWigington2O25]

If you're old and have nothing to do just hand water coconut coir three times a day it works great

[@Just4Growers]

I’d recommend a 70/30 coco/perlite mix for that watering frequency.

[@DaneWigington2O25]

@@Just4Growers I have a bag of it right here I haven't found it necessary I like to use it for cuttings

[@medrojestro2568]

Bro this song is great

[@Myco2bag]

God I love your videos! incredibly helpful and informative! keep up the good work

[@Just4Growers]

+MYCO2bag Awesome to receive that kind of feedback. Thank you Myco!

[@arisamatore1396]

Anybody knows a cheaper alternative for the bluelap connect? The cheapest i found is about 411 euros shipped from US including taxes and shipping. If there would be a cheaper alternative brand idlove to hear it.
