Good Morning!

I have googled and searched and cant really nail down a good answer for this. So I figured I would ask here and maybe get a lot more different answers and ill be able to average them lol.

Anyways, title is self-explanatory. How far away should my 315W CMH Light be away from my plants during Veg Stage? During Flower?

During the Seedling Stage I had the light about 20-22'' away from the plants and they grew well, but they did stay pretty short. Well what seemed short to me, 3'' after 16 days.

Did me having the light too low lead to stunted growth? (the plants didnt want to grow any taller to avoid getting closer to the light)

i found the app and used this (from a different thread) as a guide

Seedling/rooted clones 5000-10000lux. (Your are stressed so 7500for a week and see how they go.

Un rooted clones under 5000 lux.

Veg 18/6 15000-45000 lux

Flower 12/12 40000-65000 lux

Always start at the low end and slowly increase. 3-5k every few days to a week. You will find the plants almost grow into the increases and moving the light is far a few between.
