i going to be doing it in a closet 2x2x5 with t5 on the side
could i get decent success with the 150 hps?
should i just get 250 hps
cant for sure handle 400 hps heat
hiya firstimegrower1, is that 2' Length x 2' Width x 5' Height? if so I would plump for the 250wHps, less heat issues to worry about(Though you will still need to monitor Temps & Humidity~just to be on safe side) A 250wHps in a Closet that size will IMHO give you pretty good results(21,000 Lumen Veg bulb & 32,000 Lumen Flower Bulb) walls will be close so if you paint Matt White will get good reflective light.
Have or are you going to Vent/Exhaust out of the Top of Closet, or on side nr Top? Passive or Fan/Filter kit? and what about intake?
Peace
OH, what strain and how many Gals you thinking of doing
EDIT: Reason I said the 250w is I have read the 150w is not so good on the Watts>Lumens>$$$ Ratio running costs
