hey im a first time grower,im growing bubblegum and they are 50mm after 4days,im using 4000k cfls what effect will dat hav on vegging?and any suggestions plz!!!
4000k is a suboptimal light for any cycle. 2700k is for flowering and veg should be 5000k to 6500k (daylight). Try getting some 6500k CFL's. also check the CFL tutorial in this forum.
