I have a 1000w hps light how many plants could that light do? and is it safe to put the mirror foil around in veg stage help would be greatly appreciated
It is not the # of plants, but more like the # of square foot it will cover. A 1000w HPS will probably produce about 100-140k lumens so rougly 30 to 40 sqft. Now you can SOG 30 plants in the space or SCROG 6 monsters... I would not use a mirror, get some mylar, or panda-plastic, or even white paint but not a mirror (or aluminum foil either). GL!
