deeunit1answered grow question 3 years ago Your plants will grow but your buds will be very skinny with 200w.Are they 100w each?You need 600w of any type to get those fat nugs,Its nonsense them saying a 300w LED will replace 500w HID.600W LED compared to 600w Hid and the buds still don't get as compact as the HID.You do get more oils due to better spectrum with the new LEDs though.Not sure what a 300-450w CFL would be like if added to the Mars.The CFL only need a £10 E40 socket that plugs straight into the wall.I add the blue ones at the end of flower for the oil.
