150w x2 or 1x250w HPS

[budnasty]

I was wondering for a 2x2 Cab would it be better to flower with:

A) 1x 150w HPS and 1x 150w MH or
B) 1x 250w HPS or
C) 1x 250w HPS then change during flowering to 1x 250w MH or vice versa.
D) 2x 15ow HPS

D

2 x 150w!!!!

or 1 250w and 1 150 ?

dont change to mh that will waste your yield with such small wattage



do sea of green or do screen of green to get effective yields!! other wise you wont get anything really?

why not use a 400w hps? instead of 300w?

I actually wanna build a 2x4 cab now. Im going to Scrog it but now im stuck between 400w or 600w hps. If the 400 can cover the area without problems i will do that but more light could never hurt.

In a 2 x 4 cab set up the difference in heat output between a 400 watt & a 600 might be a significant factor to keep in mind ,,,

More light is not the problem, but the intensity of light will increase the temperature of the room, so make sure the temperature remains less, and the distance form the plant to the light has to be maintained, there should be a distance of 20 to 40 cm from the plant. whi:harvest:ch will not harm your leaves..
