When I saw people were searching for this on Google, I just had to write a post about it. Below is an excerpt from Suite 101 about Early Research on Plant Growth and Music.
Early Research on Music and Plants
Dorothy Retallack, a researcher at the Colorado Woman’s College in Denver, published her work on music and plants in 1973 in the book The Sound of Music and Plants. In one experiment, Retallack found that plants thrived when she played a tone intermittently, but died when she played the same tone constantly. In another experiment, she found that plants grew better when she played “soothing” music on the radio, whereas rock music affected plant growth negatively.
Another of Retallack’s experiments sought to discover what kind of classical music plants liked best, finding that plants exposed to North Indian classical music leaned towards the speakers, while plants exposed to the modern, dischordant classical music of composers such as Schoenberg leaned away from the speakers — but not nearly as much as the plants exposed to harsh rock music.
Isn’t that interesting? I didn’t find the study report, just the reporter’s view on it, but nonetheless, its interested to hear a scientist make claims like this.
What do you think?
You could try your own experiment or research more about the topic. I figured it would be insignificant gains at best, but anything is worth a shot! Here is a link to a experiment you can do yourself.
Leave your results and thoughts in the comments below. I can’t wait to hear what you have to say!
Here is an example of a Grow Box made out of a dresser. It is very easy to do because the frame of the grow chamber is already made.
So you want to start an indoor garden but don’t know how to build a grow box. Building a grow box is actually simple once you understand the mechanics. Today you will learn every thing you need to know to build your own grow box.
The following guide will walk you through the basics of constructing a grow box out of an old piece of furniture. A lot of indoor gardeners are also very enthusiastic about recycling, so this should really hit home for a lot of you. The dresser grow box could be considered a grow cabinet, whatever you want to call it, the function is the same.
5 Reasons You Need Grow Box Plans:
1. Grow Room Ventilation: There is too much to say here. You will obviously need some sort of exhaust. The size of fan you need depends on the size of your grow box or grow room. This simple grow box uses PC fans which can be wired to an old PC power supply very easily. You can also control the timing of the fans by putting the power supply on a timer.
WARNING: Do not use the biggest power supply you can find. Stick to a smaller power supply with low wattage because the fans use very little power. If you do not know what you are doing, use a pre-made fan that you can just plug in. For 20 bucks you can get a dryer type ventilation fan that can be attached to ducting.
Cut a hole in the back of your box and screw your fan into place. You can also use epoxy or strong glue.
2. Reflective: Reflectiveness should depend on your budget. Aluminum foil is probably the cheapest material, but it certainly doesn’t reflect the most light. Since you will likely be using small grow lights, you will want to get the most out of it. White poly or Mylar are the premium choice.
3. Water proof/Bug proof/Mold proof: Water proofing is one of the most important things about building a grow box. All hydroponic systems should be in water proofed grow boxes, or outdoors where they can’t possibly make a mess. I’ll discuss bug proof more in the next point. Mold proofing takes a little common sense. Don’t use carpet for the floor of your grow box or anything dumb like that.
4. Air tight: You will want your grow box to be air tight so that light doesn’t escape, bugs will have a harder time getting in, and you will want control of the ventilation.
5. Odor control: Some people enjoy having fresh herbs, vegetables, and fruits growing in their house, but don’t want their house to smell like a garden or green house. Some people just don’t like that smell. You can get a carbon filter for the unwanted smells, but you will need to get an inline fan, which could dramatically raise the price.
Electrical Components
Please make sure all of your electrical components are away from possible water sources. You should place your outlets on the out side of the grow box and hung up. The last thing you want is water in your electrical components.
Key Components
The small desk fan provides plenty of air movement in this small grow chamber. Here you can see two of the small ventilation fans and a few 23w CFLs. You want to get the most surface area of each bulb facing towards the plants. Notice the fan is pushing air OUT of the box. The fan at the top is drawing the heat from the lights and pushing it outside the grow box. The lights are what make the grow chamber's temperature rise. You don't want your plants to catch a fever!
-General rule of thumb: 400CFM exhaust to 100CFM intake. Play with these numbers to see how the temperatures and air flow change. I suggest hanging digital thermometers in various locations and heights in the grow room. There are thermometers that also tell you the min/max temperatures from the day. Knowing those temperatures allows the grower to understand how their daily temps are fluctuating. Indoor grow boxes are much more efficient when they are running cool.
-Clean Green Tip: Clean grow rooms are happy grow rooms. Use carbon filters on exhaust fans and HEPA filters on intake fans. Use gas duster cans to spray away any dust on fan blades. Spider mites love to live in dust and travel through the air. Avoid spreading a spider mite infestation with a little preventative pest control.
PC fans are great for small grow box ventilation and circulation.
There are a few different ways to ventilate your grow room depending on the size. Small PC grow boxes, and any box roughly 2’x2’x4′ could be ventilated with PC fans or one small ducting fan. Small bathroom exhaust fans would work but may be too loud for the application. A closet grow room will need a 4″ or 6″ inline ducting fan. The inline fan can ventilate the room and clean the air with a carbon filter. If you are using metal halide or high pressure sodium light bulbs you will want the inline fan to push the air through air cooled hoods. Below is an example.
The hot grow lights are cooled in this hood. The white ducting is the entrance for the air that is coming from the inline fan. The air is pushed through the shiny duct and to the outside of the grow box.It is essential to cool hot lights in some way. You will notice healthier plants and great results!
Key to indoor gardening: Experiment with everything to see what works in your grow room.
If you understand the principles behind the practices – you will be able to make things work with what you have. Try using a bathroom exhaust fan as the grow room exhaust. Bathroom fans are rated with CFM just like inline fans. They practically work the same. Control the flow of air with quiet insulated ducting. The noisy vibrations will certainly get annoying. Look for more posts in the future about ventilation and grow room air circulation.
