OK Quick Question i am growning indoors in and area of 2x3x6 i already have one 400w mh/hps with a digital ballist. I want to get some more lighting and i was wondering would it be better to get...

a) another 400w digi ballist lamp to provide a full spectrum of both mh and hps light and also a hood that has room for 2 bulbs

or
b) a 6 bulb 4 foot long t5 setup to provide side lighting

which do you think would insure a better harvest?

the 400 watt would help do it better if you can keep it cool and the heat dosen't build up.

I am not an expert, but I think you have plenty of power already for your space.

I have used two bulbs before, in a similiar sized space, but for the different stages of growth. MH for vegg, HPS for bloom. I had pretty good results.

What are you doing for ventilation?

i have good ventilation the air cooled hood w/ 4'' inline fan and 2 6'' fans for intake and ventilation...temp is not an issue but i want to know if the extra wattage from above will get to the lower branches in plants that are 3-3.5ft tall or if its better to go with side lighting with flouresants

Nice ventilation.

The 400 would work better IMO. The local hydro guy aways says "the more power the better".

If you can ventilate..and keep the temp PERFECT.... HID is always the way to go...

hps HID for flower. if temps and ventilation are not a problem then i suggest getting a new hood. Green Gold Hydroponics something like this. that way you can maximize effeciency with the area that you have combine your existing 400w with a 600w hps and you have 1000w total. just a thought.

Whoohoo, let's stop right there! How high can you go? Somebody's gotta stop this.

If you put a 1000w in there, that would be 167 w/sqft. Definitely too much.

Right now, with your 400w, you are supplying 67w/sqft. Perfect for getting excellent results. Adding side light will increase your yields nicely.

Go with the T5s, and put them on at least 2 sides.

I see where you are coming from PR... YET

I have seen 4 - 600 watt HPS lights over a 4x6 SOG and the results were amazing...

cheers

Exactly. Like the man at my local hydroshop says - the more power the better.
