how to make a grow box from a to z

by:Grade     2019-12-31
A closed growth box system will enable you to create and control your own growth environment such as sun, rain, wind, air, nutrients and pest control.
I recently decided to build a growth box and measure 5\'x2 so it can be placed in my small apartment.
This planter box is designed to help me with my interest and love for exotic plants.
The purpose of my article is to inspire people with my ideas like other people\'s posts inspire me.
This is my first long-time follower.
So, please bear with me, be gentle.
Before going out to buy the material, the first step I took was to determine what exactly I needed to reduce the cost by not buying anything more than I had to buy.
I do this by using a free program called Google Sketchup downloaded from Google.
I highly recommend it because it allows me to build the box in 3D and zoom with the handy tape measure tool that comes with it.
This program is very easy to use.
It took me less than a day to get a basic idea of it.
At Home Depot, the total amount of wood used for this box is $52. Lumber list. 2 -MDF sheets.
4\' x8\' x 1/2 \"$18. 99 each7 -
$1x8 pieces.
55 optional items (
Well worth it if budget allows)4 -
$3 casters. 79 each16 -
Bolts, nuts, washers (1/4\")
About $5, this is the full list of required and optional items.
I already have wood screws. I used 2.
5 \"screws for all uses of the frame and 1.
25 \"10 wood screws attach the mid-fiber board to the frame.
I printed a template to cut the mid-fiber board and the guy at Home Depot cut it for me.
A total of 6 pieces, 3 pairs of the same size.
It would be difficult to stay in the apartment, however, I did cut 2 \"x2\" myself \".
I was going to get this box only 4\' high but not sure if there is enough space.
However, a 4\' high box only needs a mid-slim board, which can almost reduce the price of the box by half.
The fiber board parts are: 1\'11 \"x 4\' 11 \"(x2)
Front panel s2 \'x 5 \'(x2)
Side plate s2 \'x 1\' 11 \"(x2)
In terms of the 2 \"x2\" cuts, the top and bottom panels are: 2 \"x2\" and the side panels are now ready to connect.
However, I chose to put some mai la (
$20 water and electricity store 25 feet Rolls)
On the panel before doing so.
Not only does this hide the edge of mylar, it will also be fixed once attached to the frame.
I spray glue with 3m (
$13 Home Depot)
On the panel, they spread mylar onto the panel to keep it beautiful and tidy.
For obvious reasons, someone gave me a good idea to put the wheel on the box.
Anyway, I should have turned the wheel on earlier during construction, but this is not a problem.
I flipped the caster over and used it as a template to drill my hole from inside.
Next I inserted the bolts, washers and nuts and now it can move!
Now connect the sides with a few wooden screws and you\'re done with a project!
To be on the safe side, I decided to wrap Mela around the exposed frame.
This is the structure.
I did a lot of things looking for fans.
I found that the fans of such a small growth box should work very well. They are computer fans.
Fan specifications: size: 80x25mm fan speed: 2000 RPMAir flow: 26.
8 CFMNoise: 21 dBAPower: 12 V, 0.
12AI plans to use one fan for the light and two fans for the growth room.
I bought these fans for only $4!
The two fans will replace the air in the growth Room 3 together.
35 times per minute, or 1 time every 18 seconds.
Since the minimum is every 5 minutes, this should be enough.
One fan in the light will replace the air at twice the speed of the growth chamber or every 9 seconds.
Now that I have finished the structure, the photo of the fan I will be using is the time to install ventilation and lighting.
First, I will install ventilation for the lighting added later.
I made two holes for the fans.
I use 1 \"hole saw drill bit in fan shape and cut out the gap with saw.
There is a more efficient way to do this, but it works with the tools I have available.
Finally, the fans were right in the hole.
Any space left will be filled or covered.
The fan fits well.
I connected them to the universal power adapter I bought at the warehouse for $12.
This reduces the voltage on the wall and prevents me from exploding again. (
I tried it once. )
Like movies, pop music and smoke.
Usually 15 am ps comes out of the wall and the small fan is only needed. 12 amps.
This is the picture of the power adapter I connected the fan to, to be safe and to prevent the fan from exploding.
I added some images to help show the rewiring process.
I just cut the tip with an RCA cable and splice it to the fan.
The RCA cable works well because it has two conductors inside, just like a fan, and keeps it clean and tidy.
I also have some RCA cables attached to the fan, giving me more length so that the two fans can be connected on the back.
It\'s very easy to connect, just stay consistent.
I connected the red and white, the black and the shield, and it worked very well. Then the other. .
I then wrap it up with tape to keep it safe and moisture-proof.
Finally, due to the heat up, I put the air intake in the bottom right corner of the rear and the exhaust in the top right corner of the front, which is the best place to remove it.
There will be a piece of glass to separate the growth room from the lighting room.
The following figure shows the two locations of the growth room and ventilation.
I connect the two fans together and then connect the two connected fans to the power adapter with a wire.
Some safety features can protect me in case of an accident for some reason.
It\'s time to install the lamps.
Only two screws are required to install the MH fixture.
The next step is HPS.
I installed the fixture so I just need to remove the bulb when I don\'t use the other one.
Look up the picture of light sq from the bottom of the box when should I use metal halides (MH)
Plants grow light? Metal halogen products (MH)
The lamp produces a balanced spectrum closest to natural light.
Using metal halides plant growth lights, plants can grow from beginning to end.
If there is little or no natural sunlight, MH is the best type to use the primary light source.
The equilibrium spectrum of metal halides contains common blue and red wavelengths required for rapid leaf growth.
Ask me when I should use high pressure (HPS)
Plant light?
Sodium high pressure is 10-
15% more energy saving than metal halogen lamps, but no balanced spectrum.
At noon, the HPS will emit an orange/yellow light similar to the solar spectrum.
In terms of promoting the growth of flowers, HPS is the best light supplement.
Next is the air filter and ventilation in the growth room.
I picked up some heavy ones first.
The chicken line on duty in the warehouse. $5 for 2\'x5\'.
Next, I use a little math to figure out how big the shredded chicken is.
I need a cylinder measuring 2.
5 \"and another 3.
5 \"to fit my settings.
The formula is (PIE x diameter)
= Length of shredded chicken.
I then compress the test and make sure it meets its requirements.
Then I made the outer cylinder and tightened the zipper.
Check it out and it looks good.
Useful tip: After the zipper is tied, use the closet bar or something similar to the round chicken line.
Wrap it up with underwear-
The hose that holds the activated carbon to the placeI will use two of the fans.
The entrance is on the side and the exhaust is the rectangular part.
I will connect both ends of the PVC to the entrance of the squirrel fan, breathe in the air through the filter and drain the box.
I will then use the dryer hose to send two exhaust cylinders to the attic through the ceiling.
No one will notice as the ceiling of my apartment drops.
I went shopping at Home Depot again.
I bought some caulkers as gaskets for the filter.
It\'s about $5.
I cut a piece large enough to wrap around the bottom all the time to keep the center screen in place.
Perfect job!
Very comfortable too!
Then I bought some activated carbon at Petsmart for $20.
I ended up using only the third carbon and filled most of the filters, leaving room for more spacers and PVC joints.
Then I capped it and almost finished it.
All I need to do now is seal it with tape and force the air through the middle to make sure it goes through the carbon.
Now I have attached the fans and put them in the growth room where it does not destroy the light at the top.
I want to install it on the side of the box to keep it low profile and prevent it from blocking the lights in any way to install air ventilation, first of all, I made a hole in the squirrel\'s exhaust to fit in a comfortable environment.
The first hole is cut and this hole will be used as a reference for the next hole.
The second hole is a bit tricky.
In order to find the right position, I had to keep the filter and fan together, remove the filter and track the exhaust, but ended up working.
To keep the inside clean, I decided to run the wires out of the same hole.
Squirrel fans will be connected like computer fans, which are shown in the previous steps.
The following figure shows the wiring work done by the fan.
The next step is to seal all the holes in the box with tape.
Especially around the filter to prevent any unfiltered air from escaping the growth chamber.
I also glued the inside with tape to make sure there is no air to escape without filtering.
All the holes and wires are fixed on the box by air.
Here I don\'t have to cut off the power to connect to the squirrel fan because I can work without cutting off the power.
It saves me a bit of time and the hassle of using any connector.
To relieve the pressure on squirrel fans, I made this sling with a zipper to support the other end.
Close-up of the sling in action.
All I need to do is seal the PVC and squirrel fans and let them air tight and just install them.
I put the squirrel fans too close, but it\'s easy to fix.
I just sanded the PVC with sandpaper until it fits the way I wanted it.
I will also twist a piece of wood under the lower squirrel fan for additional support.
I even stuck the base and the door inside.
A really cool feature of this particular power supply with optional voltage is that it acts as a variable speed control for the fan!
After I finished wiring the fans and made them sealed, I installed some CFL which was only used in the early stages of growth.
I mistakenly thought it was the socket adapter for the socket and picked up two cool outlets to split the itters.
Fortunately, I found them useful.
I installed two power strips on the opposite side of the box.
I screwed the extra screws on the side of the box, and I can choose to adjust the height of the power strip later if I need.
This is the setting, a power strip-$3Adapters -$2 eachCFL\'s -
$7 for two finished products. I don\'t have any specs for this final product, but the weight of each bulb is 100, considering the way the socket adapter is installed, the weight of these two lights looks a bit too big, so I used some zippers to fix the lights to prevent them from falling off.
What does this box look like now.
All I need is the glass and air intake in the growth room!
I just added up all my receipts for a total of $334.
The money spent on the box.
Here is the action of CFL.
As you can see, I used two higher spectrum bulbs at the top and a lower spectrum bulb below to expand the light range.
I can easily add more bulbs, but this should be enough for one or two plants I\'m going to plant in the first two weeks before I start HIDs.
Wiring is very simple for two fans.
I just connected the two wires on the RCA cable to the power supply.
The special power supply I use is a two-pronged approach and I only use it to reduce the power coming from the walls.
The power supply has two leads, just like the RCA cable.
For the computer fan, I just cut off the tip/connector of the power supply, which left me two leads.
I just connect the two leads of the fan to the power supply, that\'s it.
The fan didn\'t rotate when the wire connection was wrong, so I tried another way and it worked.
Before you seal the connection with tape, just make sure the fan rotates in the right direction.
For squirrel fans, I managed to get them to work without having to cut off the tips like I did with computer fans.
Because you are facing such a low level of power, there is a lot of room for trial and error.
Just don\'t plug the fan directly into the wall.
I use the Caulker specifically as a flexible gasket.
I didn\'t use it as a liquid insect repellent and I just sealed the end with tape.
This is the easiest way to seal the end, forcing the air to be sucked through carbon.
I actually have two power supplies to power two fans.
The computer fan uses almost no power.
I \'ve been thinking about using one power supply for each squirrel fan, but for now I \'ve connected two to one power supply, which is OK as well.
I am thinking of using a separate power supply for squirrel fans as they will consume more power (1.
In contrast, 2 amps.
12 am ps \'computer fan \')
Than computer fans, they don\'t seem to run at full capacity.
I have the platform less than 6 points from the back.
I then lined up in the area below with a black plastic cloth to help absorb the light.
On the right side of the box, I put the tape strip where I was going to nail it to help reinforce it and prevent plastic tearing.
It seems to work very well.
I did the same thing on the left, but with screws so I can remove and replace the plastic when I want to see it.
I found a spare hook and did the same thing to the bottom center of the plastic board as when I nailed the plastic board to the box.
This allows me to remove the film when I want it and keep the hole intact and don\'t open it every day.
With this ventilation remodel, I keep the fan low in front of the box, it blows air at the bottom and then from the back inside.
It works very well because when everything is sealed, the plastic will tell me that the air will definitely be pushed inside.
The bottom is lined with a black part of the plastic cloth, which seems to prevent light from entering, while allowing air to enter.
The hardware shop was cutting custom pieces of glass right next to me on the street.
Just tell them what size they have in a few days.
I believe both are 1/8 thick. tempered (cheaper)
It finished the work.
The size I get is less than $20 per piece.
With the basic structure of this box, it is easy to install any adjustments or add any items.
Thank you for reading my instructions, please vote for me if you like.
PS: I originally wrote this note in MS text and arranged the pictures in order.
I don\'t know how to make them appear in structure in order, I have bound html etc. . but no go, :(
I\'m still trying to figure out if anyone wants to throw me a bone, thanks again.
