found these can anyone advise. would it be better than my 300w dual spectrum CFL with a reflector?
Let me know your opinions I'm on my 1st grow using the above CFL growing some autos.
Or would I be better shelling out £60
For a 250w hps and ballast?
I'm growing in a 1.2x.0.6x1.8m tent with good negative pressure.
Ambient room temp outside the tent is 24-29.
Thanks ahead people.
