Alright mate:thumbsup:I will throw my ten cents worth here lol.The second light with the glass would be better if you have the right fan,compaired to the cool tube i found that they give better light intensity derected towards the plants and are exellent for scrog and sea of green but if plants are grown normaly they dont do as good as the cool tube as they can be hung in all sorts of angles which is great help when growing monsters.What method of growing are you planning?the postman.
