No, I'm talking about the driver. You're just plain wrong. The closer you are to minimum driver load the less loss of efficiency.
Edit: Turns out I'm the idiot. Posted a graph below.
You can make your own feminized seeds with colloidal silver. I would use the smaller cabinet as a perpetual veg area constantly popping new seeds to feed the flower cabinet. You don't even need feminized seeds though, it's just more efficient than having to remove males during veg.
An oversized heat-mat attached to an inkbird 306T is worth it's weight in gold. You can set different day/night temps. Throw some styrofoam on that garage floor and put the heat mat on top.
Flushing absolutely works, but it's a tradeoff where you're going to get a lower yield at the expense of having a higher quality smoke without having to jar cure it for months first. When I do fresh-frozen there is no reason to flush at all because I'm not at risk of extracting plant sugars...
They have 3.8cft promix bails which weigh a whopping 60 pounds available on 2 day prime shipping! It's just like 3x the price of a hydro store. I usually just get 10lb bails of coco though because I am lazy and don't like to go to the hydro store for cheap promix.
Upon re-reading. I had mis-interpreted you to think it was miracle grow potting mix, but it's miracle grow garden soil. That's probably your culprit. It will keep compacting more and more with each watering but as the roots grow out into the foxfarm it should resolve your issues.
That should be fine. The roots are mostly still in the solo cup full of miracle grow, since you just transplanted. My guess is overwatering plus transplant stress. Overall they look very healthy so I wouldn't worry.
Miracle grow is also very heavy, so you might be over-watering, even if you added a lot of perlite. I always have to use way more perlite with miracle grow than with any other potting mix.
Either way, it's probably the problem. Measuring runoff indeed means nothing, and your soil ph might be 3 right now. You could scoop some soil up and make some mud with it and measure that, or use a soil ph meter, but the runoff is totally useless.
They absolutely are. It's no wonder that china makes so much money ripping off american stoners. They don't even understand what efficiency means. All they know is if it's blurple or not.
