I am wishing I didn't use all the seeds already so I could do this as well! Im up to 5 black seeds as of this morning, and the inside of the cups smell musty. I think they are all goners... :(
BTW, your asking what is the best pH down to the hundredths place. This tells me you plan on screwing with it constantly. pH is hard to hold at such a degree of accuracy. In the end most will cause big fluctuation trying to do so.
Exact pH is not anywhere near as important as stable pH!
Air temp is around 78 F. Lights are 120w aquarium LEDs raised 16" up running 24/7. I plan on running howard resh as well btw. I was just afraid to run full strength at this age.
Thank you. Much easier to find info now that I know the name! I just wish they sold panda in 4' widths. I am familiar with it though; I use it on my grow shelves.
Burned, as in too much light? I didn't think I was over doing it. Each 2 trays is under a 120w LED raised ~ 16" up. 50% royal blue; 50% mixed white, red, and green. No uv that I am aware of. They are aquarium LEDs afterall, not pot LEDs...
Thank you.
Seeing that they are still very young, how much calcium nitrate would you recommend per gallon?
They have never seen ferts so far btw, just whatever is in promix.
Or should I start a full spectrum at about 10% normal strength?
N NO3 - 19.000ppm
N NH4 - 1.800ppm

Nah, they look great! I would not change a thing.
The only piece of advice I can give is that glossy white is more reflective than shiny silver when it comes to walls. On my grow shelves I used what is called panda liner. One side white, one side black.
I apologize for the blue white balance issues. Im using aquarium LEDs and they are very blue. Taking pics with my cell, which doesn't have manual white balance to correct them.
A few types of plants have very crinkled up leaves. Some have leaves that are highly cupped. Any issues?
BTW...
May I add, that keeping the soil warm is the only concern I see with this approach. Im in Savannah, GA, so I am a little afraid the soil might get too hot over the summer! I am guessing that weed fabric is breathable enough that it shouldn't cause too much of an issue.
