    Overwatering

    Use coco coir lol, that stuff is *MEANT* to be wet, in fact you should never let coco coir dry out as it has it's maximum oxygen retention when it is wet.

    Reading PPM/EC - Scales and Measurements

    You should use EC (Electrical Conductivity) as that is the actual physical characteristic being measured and it's units are mS/m (microsiemens/meter). The picture I've attached, however, will provide you with all of the conversions. You can read all about the *science* behind it here...

    Arduino programming

    I haven't looked through your code yet my head is splitting, but if you are using a device over SPI (serial peripheral interface) that has MOSI, MISO, SCK, , SS, GND, VCC on an Arduino Mega they use different pins then an Arduino Uno. Specifically MISO=50, MOSI=51, SCK=52 and SS=53. You can...

    What light recipe is the best plant LED grow light spectrum?

    An interesting read on basic astronomy solar radiation here: https://www.ess.uci.edu/~yu/class/ess5/Chapter.2.solar_radiation_season.all.pdf My understanding is that as the Autumn approaches the incident angle of the sun decreases which means that its light needs to penetrate more atmosphere...

    Will You Take The Vaccine?

    Then I'll be sure to let you know what information they bear out if I ever get access to their publications. I'm not a doctor, but I am a Biochemist. The microchip conspiracy makes me laugh because everyone walks around everywhere with their mobile phones and they don't give one fuck about the...

    Will You Take The Vaccine?

    They have been working on this vaccine since 2001 (when SARS, the first major coronavirus to affect human beings came around). With that being said I'm still waiting to see their research made public and not behind a pubmed or journal publication paywall.

    Veg & Flower same room humidity?

    Looks like you did the same boneheaded thing I did which was to paint (spraypaint?) the plastic lids before preparing them and then realizing afterwards that all of that paint will just flake off lol. In my case the plastic underneath isn't a nice green colour though, it's a bright orange...

    We run our ventilation through our lights.

    I made 2 of these like DIY filters out of a $3 4" ABS toilet flange, some cardboard (from a pizza box I think), some duct tape and a filter cut to shape (MERV11 or 12). Ive also now covered them with nylons as a sort of pre-filter.

    Aliens....Do You Believe?

    There are over 7,000,000,000,000,000,000,000 (7 x 10^22) stars in the observable universe. The sheer hubris of Humans to think that we're the only intelligent beings in the universe is .. well human. We likely havn't found any of them because of the extremely vast distances between things in...
