Hey this would be my first post and also will my first ever grow ... im very new to this and would just like some pro input before i dive head first into all this ... 
I have done lot of reading on threads but not really found anything to answer my questions ..i have been looking at buying a 300w led grow light to grow 2-4 auto flowering strains i have been looking to spend a max of about £100 on my light and was looking at these ..

My grow will be in a modified wardrobe that i will be adding a carbon filter to also and would like to grow in air pots as they seem like a good thing to use ..
would this size carbon filter be efficient for approximately a wardrobe thats 66inch high 45inch wide 20inch deep
Im fully open to any advise on all of this .. also would like some help on what strains a good for first timers and grow mediums ..
Thank you
Sam
