600+400w or 1000w

Hi there i have a 400w mh bulb on at the moment and would like to add another light in the tent either adding a 600w or a 1000w and taking out the 400w

4 Plants

Tent - 1.2m x 1.2m x 2m

Temp - 18c in tent and 25c at canopy lights on and 15c lights off

intake fan - 6" rvk fan bringing in cold air from outside

clay pebbles

2x 90litre oxy pot bubblers with 2 plants sitting in each

is anyone using a 1000w in this size tent ?

or even a 600w and a 400w ?

What's more important light coverage or penetration.

2 lamps will give you a better corner to corner coverage but the 1000w will give deeper penetration.

I'd go for the 1000w in 1.2m tent...

I've just finished some using a 400 dual spec hung vertically under a 600 super red hung vertically. was very pleased with the results, especially the quality and density of the side buds.

@@Baller18791 Yes I,am using a 1000watt in the same size tent,first attempt tho but all seems good,pics in my gallery.

You dont mention your extraction? Ive got a 6" for extraction and a 5" drawing air in from within the house.

Your light off temps are too low,get them above 20 degrees and lights out.

Goodluck :yep:

I agree those temps seem a bit low mate. You want around 24°c with your lights on. And as close to that as possible when they're off. Ts1

yeah i was thinking the more coverage would help yield especially where the 600 and 400 cross over?

plus im using a 400w now with the light placed about 10 inches away dont know if a air cooled reflector might be better than just getting a 1000w w/ open reflector as ive let them grow abit too much on the 10th week veg from seed

pics later on today

I was experimenting, half my tent was a diagonal scrog which produced about 4 1/2 oz, the other half of my tent I had 4 plants in 10 litre pots, they produced just short of 10 oz, I reckon I can get nine in there around the light, so with the right strains I reckon 20 plus is easily manageable. i went pretty basic, as i was experimenting a bit, was just a basic coco a + b regime, with a bit of pk. so nothing to fancy. will be tweeking things for my next grow, diferent pots, nutes, and no scrog, lol.
