30 cm COOLTUBE.

Discussion in 'Micro Grows' started by Fountikos, Mar 24, 2016.

  1. I was wondering if anyone has used the 30 cm (length) cooltubes and if it is possible to use them in a micro grow with a 250w bulb. And also if all kind of bulbs will fit into them.
    In some growshops they mention that these cooltubes can be used with bulbs up to 400w but i doubt it.
    My main concern is if they will work SAFELY with 250W bulbs.

    Some links to see the exact descriptions of the products.
