50-60Hz is an audible frequency range. The hum from a ballast is around 60Hz. It's not ultrasonic by any stretch. I'm not saying that plants don't like this frequency. The same frequencies can be easily reproduced with many musical instruments.

It's a plug-in pest control device used for repelling rodents. I picked one up online for $30. It's basically a small ultrasonic speaker that modulates between the 32khz and 64khz frequency. The literature claims this frequency range is painful to small rodents but larger animals, such as dogs, would be unaffected. I don't have pets, but this statement is likely true. From an evolutionary stand point, smaller animals would have to have more sensitive hearing than larger predators in order to survive. Anyways, in the months since I bought this device, I have noticed a marked increase in the vigor and vitality of my plants. When I was running hydro I had to feed my plants at full strength solution. I normally never have to do that! I know that this doesn't count as a controlled experiment, but for how cheap the device was and how well it worked, I'd say it's well worth the risk. I recommend others try this and see for themselves. It's also a better alternative to blasting metal 24hrs a day for three months (not that metal isn't great music, mind you). Look at it this way; if I'm wrong, any potential rodent problem will be solved and that's the worst case scenario.

It is not an ultrasonic speaker unless it can reproduce frequencies above 20kHz and below 20Hz. 32Hz is not ultrasonic. Ultrasonic would be a very high frequency, above the audible range of human hearing. It is also not a subsonic speaker since 32Hz is probably around the lowest audible frequency that most humans can recognize.

I am not trying to be critical of you or anyone here. I am an audio engineer by trade. I have friends who build high-end audiophile and studio mastering speaker arrays that cost many, many thousands of dollars. I hate to see folks being sucked in to a "system" that costs a lot of money when it is totally unnecessary, at least from a hardware standpoint. The Sonic Bloom speaker device is of questionable value to me. There is nothing special about that speaker array. The only thing unique about the system may be the foliar feeding nutes and the frequencies they have isolated that helps the plants grow. That CD could be ripped, flown into a spectrum analyzer and the frequencies isolated, analyzed and reproduced with just about any test tone program. It's not rocket science, though I do respect the R & D they spent in isolating beneficial frequencies and developing a product that helps augment the way those frequencies affect plant growth......if they actually work. I am not advocating ripping them off by taking their R & D and reproducing it without paying them for it. I am just trying to contribute a bit reality here relative to sound reproduction devices and the terminologies that are being used. 32Hz is not ultrasonic and can be reproduced by many different speakers that can be mounted in a wooden cabinet.

Has anyone actually tried this method? It sound like it def worth a try. If you have done it care to share any finding you might have. Thank you

Okay, I've been gone for awhile, but I did set up the circuit that dug posted, and took it to my electronics lab, to test it out. Turns out it's generating a 200 kHz signal which is way higher than we need. I'm trying to get my circuits professor to help me create a better circuit that will be within the 30-50 kHz signal we're looking for. Will let you know.

He said it operates in the 32-64 kHz region, not Hz. 32 Hz would have no effect on rodents

Hey mate. I think I can help you out with that. Just change the C1 capacitor with a bigger one.

By the way, give it a go with the 200KHz, see if you get any resuts, you never know, right?

Cheers.

Ahhh.....kHz. that is ultrasonic for sure. Not sure where I went off the reservation with that....but.....you're going to need a tweeter that can go there.

Here's a speaker that's designed to entertain bats:

We tried messing around with it a little, but since there are two capacitors, there are two RC combinations, and therefore two frequencies being generated. They combined to make a 200kHz signal, and when we tried using larger values for C1 we just got crazy mixed signals that weren't really any singular frequency. It was funky looking on the oscilloscope, for sure.
and the reason i brought the circuit to my professor was that my tweeter was making some weird noise with the circuit as is. turns out, a 200 kHz signal messes with a tweeter designed only to go as high as 50 kHz. it doesn't work well.

I haven't posted in a while because of some bad luck in my last grow I had lost interest (Lowrder 2s feminized seeds but 3/4 turned out to be males I was pissed). I have to decided to try a grow of Blueberry because of all the praise I have heard about the strain . Seeing both of your posts (Plantricity and this one) have really got me excited. Believe or not about 3 years ago I started wondering why plants couldn't run solely on electricity becuase in essence that's all leafs do is produce bio electricity to give the plant energy but I kinda thought it was a crazy idea. I have found a few simpler ways of accomplishing this for cheaper if anyone is interested.

First the Ultrasound Generator:

SONIC PESTCHASER - Sonic PestChaser

Only 10.99 it has an oscillating frequency between 32khz and 62khz. BTW after doing some research I have found that humans can hear up to around 20khz while dogs and cats can hear up to 28khz so as long as you stay above that your pets should be fine (they use these to drive away rodents in residencies).

Then for the Plantricity I have found that old cell phone chargers produce around the same 10v 500ma range small PV cells produce. I had three or four just laying around. So free or next to nothing and you can control when they are on and off so you can expierment with it while there in flowering (dark period). Maybe you can leave them on all the time and growth would continue even when its dark. I think it should be possible because the leafs think it is still getting later in the season because they are in the dark 12 hours a day. Maybe thats not right has anyone tried?

BTW Dug you have inspired me and I appreciate it. We should all strive to think outside the box as much as he does. Some times you just gotta expirment.

[Dug]

Woah, excellent post, Greenisking, great info, and a nice vibe, thanks.

About the pestchaser, you mentioned it has an oscillating frequency, did you confirm the KHz yourself? If it works on those frequencies then it will certainly deliver the package!

About using plantricity to facilitate growth during the dark hours, this remains to be confirmed, sounds deffinitely promising though. As far as I am concerned, the plants produce a certain compound to induce flowering, and this chemical can only be produced after several hours of darkness (10+).

So what remains to be clarified is wether this compound will be produced if the plant is electrically stimulated. Like you said -great understanding-," in essence that's all leafs do is produce bio electricity to give the plant energy".

If we take it a little further, what we need to figure out -and hopefully someone around here will already know- is the actual process with which this compound is produced. Why is it produced in the absence of light, exactly?

Simply put, is it the light itself that inhibits it, as in, is it photosensitive? OR is it produced in the absence of ANOTHER process/compound, which exists only under light? In the latter case, is this other process/compound also sparkled by electricity? If yes, we'll have to find another way.
But if this -elusive- compound is indeed photosensitive, or whatever other paragon causes it does not occur under electrical stimuli, then we're golden.

If this is indeed the case, it means we can possibly increase the growth rate under flowering by 200%! And growth rate under flowering is extremely important, considering the fact that the more growth a plant has during this time, the more bud it will produce within the limitations of the fowering period. Amazing prospect.

I hope somebody here has more knowledge about this subject, as I am neither a biologist nor a chemist. I am certainly intrigued, though!


Thegreenisking, good to have you around mate. Thanks for the thumbs up, and for the great info. Best of luck.

is it true that plants do not know or cannot tell how many hours of light there is period, they can only tell &/or count the dark hours.

this essesntially means, you could experiment with 20hr light cycles & 12-15 hour dark cycles without killing the plant. whether this is ideal for potency/yield/etc etc, is not knwon to me.

the reason i ask is, untils omeone compares or tries the high freqs to the plants juxtaposed to a control plant, we will never really know if the sounds are aiding or disturbing the light or dark cycle or both cycles. perhaps the high freq sounds only occur in daytime & work best then & hinder dark cycles. same can be said of the PV cell experiment. I am wary of causing yet another stress to the plant. so, looks like it will be another 4 months before I can come back & comment or say how it goes.....

[thegreenisking]

I might be bitting off more then I can chew with this grow (I am combining about 4 different advanced growing techniques). But I am going to experiment during Flowering with Plantricity on one plant and see what happens (going to do it on all them in flowering if my first experiment on a weed the useless kind). Also I have confirmed the Pestchaser (well the only way I can I goggled it and found the Manual) what I meant by oscillating is that it fluctuates supposedly to keep the rodents from getting used to the frequency. IDK if this is good or bad for our application but like you said it can't hurt to experiment (at least I hope so).

As far as what Boom was saying I would do the same if I were using soil and had another room to keep a control plant but maybe next time. I guess I will have to do it mythbuster way and forget a control (they do it all the time it ticks me off) and just try it on them all. If they continue to bud with no signs of stress I will continue.

My ultimate goal is to by able to set a speed record on harvest while still retaining yields. I'm hoping to go from seed to harvest in 2-2.5 months might be unrealistic but I would rather shot for the stars then never fly. Its all very exciting stuff who know maybe we will revoultionize the industry. Or it could be a complete and utter failure but that is science.

I am think im gonna try to figure out an ultrasonic setup myself....seems likes it def worth a try. Thanks for the info
