Hi everyone just uploaded some pictures of my grow room which I’ve modified with what I’m calling a reflection wall. I grow in a room with diamond Mylar walls to 3 sides so when it comes to crop time the buds on the open side tend to be popcorn. I came up with this idea to string an old curtain which I taped some diamond Mylar to one side but meant I had to higher the wall fans so air could flow over the reflection wall. I’ve taken some ppfd reading without the wall and it was reading 550 ppfd but with the curtain pulled across I’m getting 750 (200 ppfd more) I’m so surprised how well it’s worked. Just thought I would post this if anyone was interested and will do an up date at crop time to see if I’m still getting popcorn
