Day 28, flowering flip this evening.

So this is my first full grow using LED, as i was using HPS before.

They are 16 cm tall with the LED day 25 while the exact same strain was 38cm tall day 25 with the HPS.
They produced nearly the same amount of leaves stages, may be one more for the HPS than with the LED.

Leaves are slightly more indica with the LED than with the HPS.


At this point i'm a bit worried they are so short, bushy and compact but will see as stretch and flowering goes

    • That is an interesting observation! I have never used hps but I have grown with CFLs and t5 and I noticed similar results when I switched to LEDS. I wonder if it is because of the more intense and smaller footprint of a LEDS? My plants are shorter since switching to leds but my yealds have definitely increased. I am interested in seeing your updates so please keep us posted.

      • seem mostly due to the total lack of blue in HPS spectrum.

        • yeah i had heat issue with the HPS, and it's so much better with the LED.

          Last grow i switched to LED 2nd flowering weeks and i didn't notice any signifiant difference with stretch wich bug me a little, but this might be related to the DLI drop when switching from 16/8 to 12/12

          last time with the HPS this strain was 93cm tall in the end with 3 weeks of veg, i m curious to see how tall they gonna be in the end with the LED

          • I have a very small grow area so the heat from a hps wouldn't work.

          • Very healthy plants ! LED's are basically more efficient than HPS/MH lights. Well at least some are !!! They create a tighter plant, with less internodal spacing compared to HID lights. What size pots ? GL
