Use it and love it. I started with the CD and downloaded the tracks on my iPod and bought a speaker dock then plugged it into the timer with the lights. Mix the Sonic Bloom nutrients 1 tablespoon per gallon, in that ratio. Use warm, filtered water at high pressure. I've found the Berkey shower filter is perfect for getting the chlorine out. Then I spray the underside of the leaves and they droop way down! Clones need a 1/2 strength solution until they are rooted and it can be used every other day but less for mature plants. The next day you will notice how perky your plants look and it looks like they had a growth spurt! Stop using 1 or 2 weeks before harvest because you probably don't want to taste it. Generation after generation will improve and you'll see higher yields each time. Also your plants will be more resistant to shock, droughts, and really give it that X factor I call it! Its great for rehabilitating plants and clippings. Then I decided to spend the big bucks for the outdoor unit. This runs two hours at dust and dawn and my vegitable garden is loving it while some citrus trees I recently planted look like they are bouncing back instead of dieing!! Its pricey but you get a lot of nutrients. Seriously experiment with this, give it some time and you'll get results.
It might seem ridiculous playing music for your plants but this isn't Led Zepplin or Weird Al music it is embedded with the frequency that actually simulates the pours on the leaves. The plants actually feed through the leaves and not just through the roots. Now what do you think that will do for your buds if they don't need to use as much energy to get the nutes to the buds! Now if you can get a couple more zips would it be worth it? I think you will agree that it is! I can see this unit wouldn't be right for everyone like if you sleep with your plants! But that said, the music is pretty relaxing so I guess its not just for the plants! Also if lighting is an issue this will keep your plants growing in less than optimal light!
