I have a 48'' flourescent setup with two "sunlight" bulbs (in my closet). They are 40 W and the lumens output on the box says 2250. Are these light sufficient for my six babies to grow big? Six now but i plan on only budding the strongest two or so. Thank you in advance for the advice.
Hey LD, good to meetcha man.
Well, for a good grow, you need at least 3,000 lumens
per/sq.ft.
Measure the grow area and multiply one side of the square by the other and you'll have how many square feet your grow area is. You'll need a minimum of one square foot of area per/plant. If you have 6 plants that you want to grow BIG, then you should plan on more area. Whatever sq ft area you have, you'll need at least 3,000 lumens of light for each square foot of it.
This is for the vegging cycle only.
You'll need some HPS lights for your flowering. The same amount of lumens is needed for a minimum. MJ can use up to 6,000 lumens per/sq ft.
My area is 3.5 x 5.5 feet and I use two 430 watt HPS for a 6,028 lumen per/sq ft coverage.
Keep asking questions man. Lots of people here have already been down the same path. You'll have lots of help here.
Good luck to you man.
