Again my veg room is a 10x3 room with two 600 watt metal halides in closed glass faced hoods ventilated 6 in tubing to a carbon scrubber. The fan im using is a 6 in inline maxi fan. And right now I have no use for this hydro res so it’s on the floor. The ballasts are two 10 year old still freaking awesome magnetic switchable ballasts.
Flower room consists of 10x5 with one 1000 watt hps in a xxxl dominator hood vented at 10in through a carbon scrubber. The inline fan im using is an ac infinity cloudline 10in. The ballast is a second gen solistek.
For starting beans and growing them until I can put them in veg I use a 4 foot t5 light.
