Just set all up for my first AUTO grow.
Appox. size is 28x43" (70x110cm). I am using 2x TS1000 (disregard 315w light in the middle on the photo-its gone) which should be sufficient for the this space size.
I have done extensive research in regards to light distance/space size/etc but I am a bit confused with the light distance and PPFD readings that I am getting.
The catch is that one of the light is older type with the screw intensity adjustment which does not work so I only get full 100% strength , the other light`s adjustment works.
So I have been playing with various light adjustments/distances and right now one light is at 100% the other one around 50-60% at the distance of approx 37-38 inches from the top of the soil which in theory should be ok for the seedlings.
But, I am getting close to 400 PPFD readings (phone app light reading meter) at this setting. That seems to be way too much according to Mars Hydro recommendations for seedling 100-300.
What to do? Rely on readings or general distance of 36" at full strength is ok for seedling stage?
Another question regarding Promix HP that I am using ...... how packed/lose it should be when transferring from original plastic bag to these fabric grocery bags (approx 6 gal). Promix bags are 28L which is a bit more than 7 gallons and I packed the whole Promix bag into one of these pots//bags so I am afraid that it might be to dense and later not get proper drainage.
Any advice about my set up would be much appreciated!
