Well, for a start, Good Weed, Sir
The show you saw told you a bunch of crap.
The Schumann resonance is a standing wave in the Earth—ionosphere cavity
with a wavelength equal to the circumference of the Earth.
The lowest-frequency of the Schumann resonance occurs at a frequency of approximately 7.83 Hz.
This is influenced more by Lightning and coronal ejections than "space frequencies"
Humans fu*king with the Ionosphere have a negative influence. Ever heard of HAARP?
Space has always been there. The frequencies in space have always had an influence,
like we have an influence on each other, sometimes good, sometimes bad, but mostly in-between.
We are all travelling through space. Dust and shit also affects us, not just frequencies
AND your Growroom is on the Earth, so that's OK
Of course, your fans and ventilators have more influence on the actual frequencies "flying through your room"
Than any cosmic rays or frequency could have.
Add the frequency of your lighting,
and "Space Frequencies" only play a teensy tiny role in the overall "frequency" of your Growroom.
But don't worry, Hydrogen is always there, looking out for you and keeping you (relatively) safe.
