We re providing info for two different sized grow light setups using the same materials option 2 is just a miniature version.
Cool tube grow light setup.
Vscr6000 virtual sun open cool tube grow light hood duration.
Air cooled grow light extraction set up with insulated ducting duration.
The main use for a cool tube is to contain the heat generated by the light bulbs within it enabling the grower to extract it right away out of the grow room.
Each type of light warm or cool stimulates specific plant behavior.
Cool tube grow lights are easier to cool than a wing because they trap the air and allow it to be easily exhausted but cooltubes are not as good at reflecting light as a bigger air cooled hood.
On average the temperature will drop about 2 3 c within the grow room.
Below are the parts you ll need to put together the exact grow light setup we use.
If your goal is to improve foliar growth in your houseplants or grow leafy greens or seedlings choose a cooler spectrum bulb.
