what Lights for size of growroom

Hi all

I have a growroom that is 2m long by 1 1/2 m wide and the height is 2 meters tall.

I would like to put about 20-25 plants in here

what size of lights would you recomened using.


thank you

two 400w Hps bulbs

maybe go with two 600 watters would be better... but not neccessary

So if i only grow about 8 plants, I could get away with two 400??????

Id look into using cool tube reflectors to minimize heat.

i'm growing 6 with one 400w...

it all depends on how you grow...

2-4' t-5 8 tube fixtures will perform better than 2-600watt hid lights. VV For less.

Hi Thanks guys

VV by 2-4 t 5-8 Do you mean 2 x 4ft t5 8 Tubes ?

I have two 125 CFL ENVIROLITE Grow Lamps with the blue bulb as I was planing to use them on the the plants in the veg stage and then was going to Flower on Hps and thats what I been trying to find out the best light to use. , have not considered useing T5s, so do not know a lot about them. Do you use your T5 to Veg and Flower?


so using 2 x 4ft fixtures one over 4 plants, would give me the lumuns I would need to give me a good harvest? ( do you use the red light for flowering ?)

is this what you mean? but this has 4 tubes in each and you get two or is that what you meant by 2-4 t5 8 tubes
