    Bright light!a bright light!!

    Idk if any of y'all remember about a yr ago someone posted a link to a study done at Utah St that showed that seedlings not only can handle strong lights but actually thrive on it. I concur. These 4 are 10 days old & have been 18in away from a 150w MHydro TS 1000 since they came out of their soak & were buried.
    I just threw out my cfls & T5s 😀

          It has been my thought that if I can plant in full on Oklahoma sunshine, I can do the same under fake light. My LED stays at 100%

              Well they're obviously using it- they are 4-5x the size of the ones that I've started under cfls or T5s.

            Very good point george66 i'm guessing he's using it because he has no space for seperate lighting areas looks like to me?

              No tent true but no need for a separate section- just one quick grow before I have to move again 😀
