    Hydroponic addition of Chelates (specifically Fulvic acids) PRE nutes or POST nutes?

    This is all I can answer as I don't bother with fulvic acid or silica. Iron DTPA is good stuff. It's pretty much the only non-white salt used and it will turn whatever stock solution it's in a deep orangish-red color.

    Uh...it was just 90 degrees in there...

    Just estimate. If you assume efficiency is 38% (38W of PAR for every 100W of electricity) then 62.5W/sqft * 0.38 = 23.75W/sqft of PAR. It's good for making rough estimates of how much power you will need for any lamp where you have a decent estimate of its efficiency. For example, if you...

    Uh...it was just 90 degrees in there...

    Yeah, I wouldn't recommend using 12.5W/sqft of PAR. You'll get good results (I used it for a while), but I think the sweet spot is closer to 18-20W/sqft PAR when balancing good use of space vs photosynthetic efficiency. Anything higher is probably overkill. If you had a micro grow and keep...

    help making homemade “nuke em”

    Insecticidal soaps are basically just potassium based liquid soaps. Putting it on the soft bodies of spider mites is supposed to cause their soft bodies to melt.

    Also, is your veg/clone tent in the same room? How powerful is that lamp? That's also a heater.

    You could replace 1600W of HPS with ~1200W of LED, at great cost of course. Then you'd have 400W less heat to deal with. At 50% efficiency, you'd just about match the PAR W/sqft of 1000W HPS + 600W HPS in a 4x8. A 400W LED is definitely not going to out yield a 1000W HPS, but I wouldn't say...

    Total TDS

    The 82ppm is most likely from calcium carbonate. When you add your nutrients and pH it, the carbonate will off gas and the remaining ppm will all be nutrients. In short, if you measure 1000ppm, don't subtract out 82ppm.

    Low soil pH adjusted using high pH water?

    Amend your soil with lime.

    My opinion on flushing cannabis. (Yet another)

    The point is that the white ash is the nutrients you're trying to flush out. (potassium and calcium oxides, etc)

    2 days darkness before dry?

    After 12 hours of darkness, all the starch in the leaves will be used. There's no need to have a 72 hour or 2 day dark period. Once the leaves run out of starch, growth will mostly stop in hopes the lights come back on.

    How would your personal Grow OP look like, with unlimited $$$ ???

    My grow OP would be a fully sustainable secret underground bunker. It would be nuclear powered and capable of going 5 years before needing to be refueled. I'd have an 80W CFL for every 1 sqft of grow area.

    If you were running a commercial grow what lights would you use?

    HPS will always be the king!! LED sucks!! Please prove me wrong with 100 pages of healthy debate.
