Hello guys My 2 plants are 5 weeks in veg under 150W Hps. I just purchased 250w HPS in my growtent and planning to start flowering with the new 250w light in 2 weeks. My question is if this will stress the plants or do things what I dont want for my grow.
no. youll be fine as long as you have 12-18" of space between the bulb and the plants as well as adequate air movement/ventelation. the plants will thank you for more light.
Good advice. In order to make sure you do not burn your plants. Place your hand aplm down over the caopy. If the back of your hand is comfortably warm; That is perfect distance. if too hot; Raise lamp 2" at a time until you find the comfort range. Lower if hand is cool. Keep up with this excercise weekly. Sometimes you will see a burnt leaf. No worries. Raise the lamp 2". Hope this ehlps.
