My Constant Flow Grow Box

Hi, this is the setup i am thinking of going with to make a small in-closet grow box. if there are any sudjestions on how to make this any better please let me know.




thank you for your help, what size HPS bulb should i go with if i upgrade for the flowering cycle.

how big do you plan on growing your plants?

To the best of my knowledge, Carbon filters and computer fans don't work very well together, They don't have enough power to draw through the filter.
Good luck

dont you also need a fan pointing in the box not just out

not always it's called passive intake, you blow the air out and it will usually find a way in through all the cracks or anywhere it can.

im going to be growing a indica strain like Northern lights or White Widow. i am not sure what yet, i will prolly put bag seed in first to test out the lighting and temp and stuff so that i dont kill a plant that could make 250$.

and as for hight im looking at like 2.5 feet (give or take)

and as for the intake fan, i forgot to graw it and realized it after i posted it up, but yes a fan will be used for intake as well.


as for the computer fan and carbon filter not a good combo, what is a good setup, this is only going to be used as an odor control, so if there is a better/ easyer way to control the odor please let me know.

ohh right on

ok well it looks pretty well thought out but you will need more air flow ON your plants to build stem strength, AND 3 23w lights is NOt enough for 1-2 plants, i have 3 40w cfl for 1 plant before, you need at least 4 40w lights, the more the better. and with these lights you will need more vent.

yup, raeman1990 is right you need more light, more light means more heat , more heat means ya need more airflow, perhaps you could use multiple fans on for exhaust, and on pulling through the filter but not vented outside the box, like a scrubber, that way the scrubber wouldn't need to clean the air completely in a single pass, and there would be no filter to add resistance to your exhaust so you would get better airflow. Good luck and let me know when you start your build.

needs much better light like a 105Watt CFL =400watts 6500k Light bulbs, Rope Lights, Halogen and Fluorescent bulb - 1000-Bulbs - The Light Bulb Superstore

thanks for your help, and i will get more lights and more fans, and i will get picks as soon as i start the build
