This is my first attempt at growing. I am using a 4x4x7 ft grow tent with 1000 watt equivalent Led grow light, Growing 2 plants hibrid purple headband..my girls are right at 6 weeks old grown from clones...they are 20 inches tall.. Growing in 3 gallon pots with 40/40/20 grow medium. Using root organics nutrients. My questions are .1.. Do I have enough light? 2.. Are they growing at a good rate? 3. What kind of yield should I expect from this set up?
