is the hight of the light ok?
I haven’t had any problems yet you can check my grow first real grow is the title
If you use a 150 lamp only; You should have a healthy grow, but temper your expectations for yield and bud density. 
Thank you guys, as you see i’m using a normal kitchen exhaust fan for filtration, is’t enough and fine for 3-4 plants?
Keep your lights about 12- 18 inches during veg , and as they stretch raise them higher .
