give it 2-3 week's then put them under the HPS ,but when you do start with the HPS as high as possible and work your way lower everyday untill thay reach the desiered hight.
marijuanamat Reviewed by marijuanamat on . seed/seedling questions hey everyone, I'm a first-time grower and I have a few questions: 1. I'm germinating five white widow seeds in cut up 2L coke bottles...while I was away for thanksgiving, two seeds' taproots pushed the seedlings out of the soil. Now the question: is this common and should I be concerned about the stress this might cause them? they were green when I got back, so I'm assuming they're still healthy, and I recovered them with half an inch of loose soil. 2. I'm getting a 400 watt hps system Rating: 5
