upgrade to 1000watt hps

Needs to be lightweight and with good light spread and noise is a concern if air cooled area I'm working with is 1.2×1.2×1.2

No offence mate but I go on a forum for information not too chit chat and joke about lol
no offence taken, but if you act all serious and moody about a little joke you will most likely find others will see you as an easy target to annoy
that is the nature of this form for the most part

when you ask questions, you should not expect the perfect answer, folk have no obligation to help you
if they do help you, see it more as a bonus

you might find "grasscity" more to your liking , those cunts over there have no sense of humour either

Sorry man I did over react.

So....to answer your question.....and I'm doing a Monday morning metric to standard conversion from my head, 1.2 meters is around 4.5'.

It's my opinion that 1000 watts is WAAAAAY of an over-kill and will most likely do your plants more harm than good. Since you're looking at only 4.5'-5' in height before adding a light fixture that will take up about 8" of grow room, and then another 10" for the container(s), you really should consider getting a four-foot 8 or 12-bulb T5 HO. It only takes up about 3" of height, will light-up your area well and you can play with bulb configurations to get the optimum PAR.

That and the T5's would run much cooler than a 1000w HPS set-up. Don't believe any nay-sayers that say you can't get good yield from T5's. Since you won't be growing any really tall plants to begin with, light penetration really doesn't come into play here. You'll be able to grow your plants much closer to the T5 than you would a 1000w light.

he's not going to get an equal yield using t5 over hps. t5 is great for veg, and i'll stand by that, but i still think hps for flower is the way to go. i do agree with you though, it is definitely a common misconception that you can't flower with t5. i've seen people produce beautiful results flowering with t5. some even say the quality is better than what hps can produce. however, it is pretty safe to say t5 yields less in flower than hps.

anyways, for that size of a space, i'd honestly recommend 2x 400 watters. 1000w is a bit overkill but i've got a space similar in size to your's and 800 watts is brighter than you'd think. plus you'll get better light coverage with 2 bulbs rather than just one.

When I read his post my first thought was 400w but then got thinking about it and recommended the T5's. I think there'd be a trade off yield wise as you could grow your plants taller under a T5 vs. HID just because a T5 fixture takes up less vertical space than a HID fixture. That and the plants can get within an inch of the T5 bulbs whereas under a HID I wouldn't get closer than 3"-4". That's about an 8" taller plant.

You can yield JUST GREAT from T-5 lighting....The thing your shooting for would be Lumens or intensity of light. Say around 80K for that area.

T-5's with a proper balance of light temps or Nm range is key also.....Proper bulbs to look at would be Aquarium bulbs,,,,,costly but, the BEST way to go!

With the cost of fixtures, bulbs and monthly electric.......I might look into Plasma or Induction lighting for that size area.
While those have a high initial cost. They do run at low electric rates and long lasting bulbs that end up saving thousands of $ over the life of the bulb.

If HID is what you have to do......600 watt for that space is where you should focus.

Cheers for your suggestions and advice however I don't have enough growing skill to pull off a good yield with T5's as well as I've invested in a 600watt hips already so think I'm gonna buy a 400watt and use both together as the 600watt on its own isn't seeming light enough as there is a few bushes in there shadowing a little bit and only really good intense light in 1 spot really! Brought a new hps bulb so hoping there will be a difference fingers crossed

Good idea man, changed my mind again and gunna do 2x 600watt digital ballast and not have the turned up full

Sigh.....I am no expert on lights, but have read enough from those that I consider pretty smart in the light department.

It's my opinion that your focus on a ton of wattage is mislead....especially in the confines of the area you have to work with. I actually did the metric conversion and you're working with less that a 4'x4'x4' area (1.2 m is 3.94') and a total of 1,000 watts will fry your plants.

As I keep telling my wife...."More isn't always better". While she disagrees (usually laughing and pointing) this is true about lighting. I suspect that my telling you this will not stop you from trying....but when you look at your burned plants not too far off in the future, please remember I told you so.

What kind of hood/reflector are you using? A 600 should cover that tent just fine.

Quite right!
LUMENS are the true measure......watts are what your drawing per hr in electricity. That is how you figure cost.
