well, I am an LED guy wit h zilch experience with HPS. We are not concerned with the overall heat the the light generates only what the light is putting down to the plants.
I would recommend you look through this post.
I’m sure if you read that it will answer the question. If we need further clarification, I know just who to tag! @VelcroThumb
LOL! Been there done that . And doing it now with early harvest thanks to the rain and more rain. I only had room to dry half of my outdoor Widows at a time. Oh well
@VelcroThumb all six in a 4X4? You should be fine. My first grow I made the mistake of trying to fit 12 in the same space… I learned that lesson. They look great. Better than mine when I first started. They were a little stretched from lack of light.
Everyone says itll be fine until they bloom. I plan on doing a SCROG. A few people said those tents can fit 6 when they are clones because they dont get as bushy???
@VelcroThumb If you’re scrogging, then 6 would be too many. I’m not sure on the clones, you can follow along as the next grow is just that. Including two monster cropped clones. Stay tuned!
