Well the as far as lowering the light, its as low as i can go to keep the temps around 78-82 degrees F... As far as the netting goes its only about a ft above the plants at the moment and i plan on letting them veg as long as possible maybe 3 weeks... does that not seem like enough time to do it... also does that seem like to many plants for that space to do a scrog??? the space is 2.5ftx 4.5ft
