Ron’s Hydroponics Bottle Garden

[size=13]

 

Let’s begin where I began several years ago with this style of EBB & FLOW hydroponics garden. I wanted a garden that was small, medical marijuana legal, easy to maintain and a system I understood exactly how it works. There’s dozens of designs out there, this probably won’t appeal to everybody looking for free hydroponics plans, but for small entry-level hydroponics this is a forgiving system to learn on. You can click all pictures to make them bigger.

 

I learned about the bottle gardens from this web page:


from that main page take a look at the link “how to build Hydro Ron’s 11 plant garden”. Click on the JPEG link and enjoy a nice slide show type presentation even though you have to use your back button to navigate the entire show. There is even an interactive page where you can design your own garden at the “design a garden” link

This guy has some clever design ideas, one that really catches a new growers eye is this little 4 plant garden that wouldn't be too hard to copy if you liked that design and his $100 price tag is reasonable if you have money in pay pal. Check it out here and see what design ideas for growing Mary Jane you can come up with. Combine the ideas you get off Ron’s pages with the proven techniques we’ve used to convert the design a for growing marijuana and you’ll have a problem free garden that lasts grow after grow. If you are presently growing in soil and wonder about converting over to hydroponics we’ll provide the basic info for those on that path as well. CLICK ALL PICTURES TO ENLARGE.

Large plants can yield almost 1/4 pound

 



Is Hydroponics really for me?



YES! Growing marijuana with free hydroponics plans has been proven to produce plants faster with increased yields. Here is a short overview of hydroponics, it's very brief but there are other more specific resources at




Understanding the Ebb and Flow

 

The garden can sit directly on the top of the reservoir tub but it's easier to maintain if it's slightly above the reservoir. 2 standpipe overflow pipes should feedback to the reservoir and when flooding will aerate the reservoir when it drains back. This is all the aeration that's required because as the flood recedes the water lowering in the bottle act like a syringe drawing air back into the root zone.

 








 image 1

Most of the time the garden is at rest. Before doing any maintenance procedures you should have the garden at rest and pull the plug on the water pump, this is very important.
 image 2

During the peak of the flood the height of the nutrient solution is determined by the height of the standpipes. We recommend 2 stand pipes for better reliability. The return water falls into the reservoir aerating it in the process.
 image 3

The Ebb cycle refers to when the nutrient solution recedes and flows back through the intake screens of the now silent pump. Air is drawn back into the root zone, another benefit of this system.

 

 

 

Pumps and Equipment

 


Pumps are rated by how much they pump per minute or hour and how high they can pump. Expect a $20 pump to pump 1 gallon a minute to a height of 2 or 3 feet or nearly a meter. Most pump outlets are 1/2" like the PVC pipe so just use vinyl tubing to connect them to your garden at a T with hose clamps. I recommend one garden under HPS light and a part time garden under flours during rooting and the first weeks of vegetive growth. You want the gardens away from each other because if you purchase clones from a medical marijuana dispensary you need to quarantine them as they root. All new plants should be treated as if they are infected with powder mildew and sprayed with sulfur and serenade.

This doesn't look like a lot of complicated equipment does it? The pump and light timers are in back.

A closer look at the pump and light timers with everything on a single power strip. On the pump cord this pump came with fittings for different sized hoses.

A cheap way to get 200 watts of fluorescence light is at WalMart and these 'trouble lights' with Compact Fluorescence bulbs with timers for under $50


 image 2

The preferred grow medium for this style of garden isn't soil, it's grow rocks. Also known as 'hydroton' these clay marbles are lightweight with no jagged edges to damage roots. I boiled it between grows and reuse it.


 image 3

A closer look at a pump diagram. not labeled is the outlet port you'll attach the vinyl hose and allows you to flood the bottles. It sounds funny that you plug this into the wall or timer and throw it into your reservoir water but that's what you do.



Nutrients:



They call them 2 part mixes but most involve up to 4 parts as the growing stages progress. One major supplier offers the nutrients or 'nutes' I use in an intro pack for $17.95 at these are the BC nutrient line. Their nutes are PH buffered and easier for new gardeners
Advance Nutrients knows more than anyone about growing marijuana so check them out here they have a wealth of info.



I don't have fancy PPM meters or even a PH meter I use a $5 liquid reagent PH drop kit and I match the color of the sample to the color of another common household item Listerine. City water runs the PH 8 or 9 which is blue or green on the color scale. Yellow is PH 6 which is close enough. Tweak it a bit more with a bit more PH down to 5.8 or the color of Listerine. Go to far with the PH down and your sample will be orange or red, no good, start over. Plants needs change and you add more fertilizer as plants get bigger. Adding fertilizer generally lowers PH. Grow rock (hydroton) normally has a PH of about 8 when new, so soak your hydroton in PH adjusted water for a few days before using.




Tools and Safety:



Safety First

Since this is a hydroponics grow, there is no doubt that you need a Ground Fault Circuit Interrupter (GFCI). Likewise, any place where it is likely or possible that someone may be standing in a puddle of water and will come in contact with a plugged in electrical device needs a GFCI.


Wire your plug in strips just outside the grow area and up off the floor. Away from the grow so the LED's on the power strip don't interfere with the plants dark cycle (important!) and off the floor in case of flood. It's possible to pull a plant out of this garden for just a minute and have the flood cycle hit pumping all the nutrient solution on the floor while your back is turned so always unplug the pump and isolate all sources of power before performing any maintenance operations. A shock from a plugged in device can be lethal, take all possible precautions.


Use only HPS or Fluorescence light as they are safer than Metal Halide. Always use a glass cover with your light hood and always have a smoke detector inside the grow.



Tools

You don't need a lot of tools to build or maintain the garden. Buy a good pvc pipe cutter that leaves a razor cut so that pieces slide together easily making design and testing a snap. You'll need a drill to make the holes through the top of the Rubbermaid reservoir lid so the overflow return pipes can dump back into the reservoir. Avoid letting the drill's plastic waste get back into the reservoir system. You will also need a hole for the pump feed tubing and one for the pump's electrical cord. A screwdriver is needed for the hose clamps for the pump install and the bottle assembly. A dremel tool can enhance the look of the finished product on top of the lid but it's optional. 1/2" inside diameter vinyl tubing most likely is all the hose you need to make the pump to garden connection and perhaps make return overflows more flexible. You also need hose to pump the garden's nutrient solution out into a bucket and those fittings are from the simple parts noted further below
.

Inside the 'frog pond' we see the business end of the garden with the pump and intake tubing connected to a T inserted pointing down to facilitate the pumps pressure.


 image 2

Checking the color of the PH results with a common household item will mean a more stable PH and fresher breath! Check it outside though because you don't want indoor artificial lighting or grow lights causing listerine to look this red.

Just some old school tools and supplies are needed to build and maintain your garden for years to come.




Converting the design for medical marijuana




In case you didn't’t get it this garden is built from PVC pipes and fittings and utilizes 2 liter soda bottles for each plant location. So my first suggestion is when you make your garden cut the 2-liter bottles so they are as big as possible. Marijuana is known to make huge root balls for huge plants. Many systems use 3 to 5 gallon containers, this uses just 2 liters so make sure you at least get the whole 2 liters. The photos at Ron’s shows the bottles cut in half, and that’s no good for Mary Jane. More on this later.


Another issue I have is the way his bottles tap into each location. There is a more secure way than using the old bottle lids with a few parts in the PVC section of home depot, which you’ll be getting to know a lot about if you’re considering this.

Make 2 gardens, and if your plant limit is 12 make each garden hold 8 plants. This sounds somewhat shady but a mistake I made was building this for exactly 6 plants which is ½ the limit only to find out I had no additional taps to FILL and DRAIN the system. You’ll want extra bottles and extra tap plugs when you build it. You’ll use the extras for maintenance and light poles. Another mistake I made was using ½” PVC pipe when you can get the same sized headers in 1” PVC as well. I made 2 over flow stand pipes on my design to compensate this, that’s not a bad idea anyway.


This is also a garden that’s ideal for this article ‘Stealth Closet Cabinet Tutorial’





Parts list and approximate costs per 8-location garden

 

 

Most DIY home improvement centers are one-stop sources:
Home Depot (home de pot), Lowe’s, Ace Hardware, etc all carry a complete line of PVC fittings in the plumbing isles. You can get everything in one stop at Home De Pot except maybe the bottles.

This T has a female header that's threaded and made to last a lifetime. The male adapter has the male threads on one end and 1/2" pipe can fit the other 2 ends. Another type of T has fittings for 1/2 inch pipe on all 3 ends.
 image 2

You'll need elbows to make the stand pipe over flows or possibly corners.
 image 3

The male adapter has males threads on one end and fits 1/2" pipe on the other. It's perfect since the Bottle fit 1/2" pipe the same way a short piece of pipe connects them. Also plugs fit in so you can make screw in plugs if you remove a plant or for maintenance. Consider using them with long pipes for light poles.
 image 1

This T takes 1/2" pipe on all ends and can be used with pipe and hose to connect the pump to the system with some hose clamps.
 image 2

These plugs go into the male adapters and when you 'change oil' you can unscrew a plug and screw in a hose fitting.
 image 3

Another very common fitting is the corner with a female adapter fitting. This picture shows one in use with 1/2" pipe attached.

 

Building the bottles

 

To build the bottles you'll need 8 male adapters and 8 short pieces of PVC pipe (2") and of course 8 bottles. Clean the bottles pretty good except don't take the label off of them. The label will makes the bottles more opaque and we'll be painting the bottles later so our root zone is in total darkness, even under bright lights. Cut the bottom off the bottle so it retains it's original size. When you lay out the pieces you'll notice the 1/2" PVC pipe fits into the top of the Male adapter and the neck of the bottle equally well and this is the basis of the design. Use a piece of pipe that's about 2" long that seat's fully on the male adapter and goes to the end of the bottle's neck. This is pretty easy, use PVC primer and glue on the connections on both ends of the PVC pipe. The bottle end will get primer and glue and a hose clamp over the area that used to be the screws for the bottle cap.

 



After you have that set up you can glue a 2"x2" piece of vinyl screen over the bottle neck hole so all grow rocks and hydroton are kept in the bottles. Roots will grow right through the screen, I often roll up some screen and put in the neck as well. Roots tend to grow right through and into the plumbing and your garden should be checked for roots plugging the bottle necks every month or so. I normally trim roots the week before I flower them, after their vegetive growth is about finished. I've found no other root trimming is needed.


Once the assembly is dried I buy super cheap spray paint, a can of black for opaque undercoating and then a coat of white so they reflect light on the outside. Use skeleton pieces of the garden to hold the bottles while painting and drying between coates. In some of these pictures the bottles are covered with thick paper around the outside to further reduce light emitting into the root zone. Remember roots don't like light.

A finished bottle and one under construction indicates the reliability of the fit between all the pieces.

This one is ready for painting. The net cups in the picture are purely optional I don't use them.


 image 3

Peering into a finished bottles shows the last step is using the primer and glue to attach vinyl window screens over the bottle necks so your grow rocks can't get into the pump.

 

 

Design on the fly to meet your needs

 

The garden uses the style of pipe used in residential plumbing and is very reliable and easy to fit. With the proper cutter and some planning you can create designs on the fly and pretest the entire design without gluing anything. I have overflow pipes in my garden that are adjustable and have never been glued and have lasted several grows. After you have pre-tested your design you should glue it together. When you begin you don't really know your needs for your space and environment. People in wheelchairs for instance may design in special considerations to make changing the oil an easier one-person job.



As far as saying cut 12 pipes this length and make 2 half's then glue it all together I think it's better to turn you lose with this adult style 'Lego Set'. If you screw up and you have a good set of pipe cutters you can insert missing items or make small additions or design changes. Get the basic garden up and tested and use what you learn as you go.

 

Maintenance

 

Changing the oil:

You should change the nutrient solution every week, or every 2 weeks but never longer than 2 weeks. You should mix fresh solution and check the PH. I flush for one day with plenty of fresh PH'd water between nutrient changes, it doubles the work but prevents salt build ups. Pump the old solution into a bucket using a tap you make for the purpose. Never dump your old nutrient solution down a drain or public sewer. Always dump it on outside plants instead. Unplug the pump and sources of power for nearby fans, Work safely.

Make a tap from a threaded elbow and keep the pipe rather short so it fits any location.


 image 2

With a hose slipped on to the tap it's easy to drain this system. Always unplug the pump when installing plugs, taps, bottles, light poles, etc. Plan on pumping all the nutrient solution on to the floor right now, over the course of several grows it will happen. The pump would have come on while taking these photos actually, if it hadn't been unplugged.

My main garden sits on slats above the tank and has a valve plumbed in so maintenance on this garden is a breeze.

Troubleshooting

 

Root Bound:

You will need to trim some roots and open some blocked bottle necks, normally just once per grow will suffice. The roots can take up the whole area but plants vegged 3 or 4 weeks shouldn't be a problem as far as getting severely root bound and all may plants seems to finish okay, even the moms that were in bottles for months.


Pests:

I had some clones brought in from a medical dispensary that were infected with powder mildew. Since then I set up the 2 garden approach and keep them away from the flowering chamber under quarantine. I use sulfur, Neem Oil and Serenade. Neem and sulfur don't mix, use them several weeks apart. Serenade is beneficial bacteria you can spray on all the time but smells like pig vomit. So I do spray it around the plant base and inside the reservoir tank a bit too, it's good bacteria that eats bad bacteria for breakfast.

This plant (Flo) vegged 3 weeks, flowered for 8 weeks. It yielded 1.8 oz. The root ball is significant but not overly packed. The screen from the bottle is ingrown in the bottle neck's pig tail. Fertilizers in BC nutrients tend to turn the roots a little brown, they are still fairly healthy


 image 2

This Train Wreck vegged 3 weeks and flowered 8 and yielded barely an ounce and it's root structure doesn't look cramped at all


 image 3

Placing an empty bottle in the garden is good way to check the flood levels and notice the bubbles coming up during the flood of this little Afghooey baby girl. The empty bottle serves as a funnel for refilling the system after a nutrient change. I think changing nutrient solution often will make the most effect use of this garden's limited root zone area.
