Yup thats the good stuff, sorry i was typing fast but yes the Stoma are blocked and clogged very easily after a week or so of dust and particles sticking to the leaves from air circulation. Thats why it is very important to foliar wash the undersides of the leaves once a week or so. Its a noticeable difference this Sonic Bloom study that was made. It works with the recorded sounds of special birds found in the Amazon Rainforest alot better than just foliar washing, I think thats what gives the plants a wake up call so to say. Music helps alot also its been studied quite a bit, but I feel they didn't understand why it was stimulating the growth in their study though. It is a very interesting study. In this CD he sells its got dubbed Classical music into it so you have the birds chirping but classical music playing with it, so it doesn't drive you crazy I guess LOL. I didn't mind it was kinda nice IMO. I chill out and vibe to it while working in the garden it doesn't have to be real loud but loud enough to hear ok. They say heavy metal or fast punk is not good for this but more high frequency smooth sounds. I.E Classical, Jazz, chill house music maybe, or even the right kind of Techno I guess, Deffinately some good Marley or whatever tickles your ear drumbs good, but it should be on when the lights turn on to the time they go off. this alone will show difference in the vigor and happiness of your plants garanteed peoples.You can Take this to the Bank literally.
