hi guys this is kevin from exponents here with a deep water culture tutorial i wanted to make this video to describe one of my favorite ways to grow hydroponically and also just happens to be the simplest cheapest way to do it so if you're a beginner they're kind of curious about hydroponics you want to know what's up with it this is a good way to get started so let's take a look at what we're gonna need the first thing we need is a nutrient reservoir which houses our nutrients houses the water and also has the plants roots suspended in that water I tend to get mine from Home Depot or Lowe's because you can get sizes ranging from 15 quarts up to around 20 gallons which is more than enough for almost anything that you need at home I would recommend probably the rubbermaid brand or the Sterilite brand is your best bet for durability now the next thing we need is our nutrients and our water let's just assume for times sake that we've properly pH the water we have added the correct amount of nutrients and everything's good to go as far as our nutrient solution and I will cover that in another tutorial but for now let's just assume that this is already complete alright so if we were to place a plant in this right now it'd do okay but as time went on it would start to suck oxygen out of the water because the roots need oxygen to survive in time it would run the water completely out or sorry it would suck up all the oxygen and the water would not be suitable for plant life anymore so what we need to do is add an air pump and you can buy these at Petco an aquarium store or anything like that they're very cheap and I'd recommend just buying the cheapest one you can find because even the cheapest one is more than enough for what we need it for now the next thing you're going to need is something to spread that air throughout your nutrient solution and what we use for that is an airstone they again are found at your Petco or your aquarium store and they come in either 12 inch long lines or these three inch diameter discs and you can buy either it doesn't really matter which you buy as long as it's spreading enough oxygen and air throughout your nutrient solution now the last part of that equation is going to be the line that connects the two and it seems simple but there's a couple things to think about here the first thing you want to think about is getting 1/8 inch airline tubing make sure it's airline because then it's bendable enough to have two so it can navigate through your little system now the next thing to think about is that it is opaque it needs to be opaque because if a light is hitting a clear tube you're gonna get some algae growth in there and it's just really gonna be a hassle to clean out and just avoid it all together by getting an opaque tube okay so we have our growing media as our next thing to consider now I would say for anyone starting out to buy hydroton and what hydroton is is it's an expanded clay pellet it's kind of brown and it has some black specks on it it is by far the best growing media to start out with because it's inert meaning it's pH neutral so it won't mess your nutrient solution up at all it is reusable and it's inexpensive so if you can't find that locally you can always order it off Amazon or any hydroponics store online we'll have that for you the next thing you have to think about is what you're putting your Hydra tone into and for that I recommend something called net pots net pots basically look like a cup that has excuse me a bunch of holes kind of cut into it it creates a mesh and what that mesh allows your plant to do is have a strong and robust root system if you were to have a normal cup which is some holes drilled in the bottom there'd only be one direction for your plants roots to grow but with net pots you can actually have roots spreading out from all different areas of your net pot which is really great and it promotes a vigorous root system so now that we have our entire system built we have our growing media selected the next thing we need to think about is how to get our plants in this system so for that we'll take a top-down look at this system these two black holes that you're seeing are drilled in or cut in to the surface of your tote I tend to use a hole saw for this but you can just cut it out with scissors if you don't feel like you're buying that bit because it is kind of expensive the next thing you're gonna have to do is drop the hydrogen into the net pots put your little seedling in as well and then plop that into your system and when it's all said and done it looks something like this now this is the beauty of deep water culture all you have to do is grab a couple ingredients from Home Depot's and Petco and you can have this system that produces really healthy really vibrant plants for a long long time and it doesn't really even take too much effort the only thing you need to worry about is changing the water every month or so and in the meantime making sure that the water level stays constant so you just have some mixed nutrients waiting and as you see a drop the best thing to do is just pour a little bit extra in and you're good to go so that's the basics of deep water culture if you want a cost breakdown I've put a rough one here and you know this is gonna change depending on what kind of materials you decide to use if you want to use party cups and cut some slits in them you can substitute that out for net pots if you want to use a different grow medium you might save some money and you might already have a reservoir at your house but that's the basics of deep water culture if you have any questions leave them in the comments and in the video description I've also linked to a more in-depth tutorial on how to build your very own hydroponic herb garden so check that out if you want to and also subscribe and like the video if you liked it and if you didn't leave a comment and maybe I can help you out this is Kevin from ex ponics goodbye
