6, 600w or 4, 1000w?

[Sure Shot]

Which is the better way to go? 6, 600w or 4, 1000w.
I have 2 8'x4' trays, what do you think?
All opinions welcome!

I'd say the 4 1000's if going for budding. Just keep an eye on heat spots, make sure u got good ventilation, couple of oscilating fans.

idk if he could control the heat i think that the 6 600watt would far exceed 4 1000. but thats just me.

600w is good. i will be having 1 600w on 15 plants..should be fine for even 30

yeah, id vote for the 600's just so u could have more points of light as well as keep the heat down. are u planning on aircooling or what?

 

[randk21]

a 600w for 30 plants!? really? I dunno either. I myself am gonna go with a 600w but thats just based on what i can afford. I've head a 1000 watt can do a 8 x 8 room but I myself want max results...

im packin about 48+ clones under my 600w. right now i have about 39 clones and three large plants late in flowering. i have 20 more clones almost done rooting too. one week veg time and keepin them in 36oz cups.

These would be air-cooled.
Currently I am using 4 1000w.
But I'm thinking 6 600w might be best.
Here is my room right now.

4000w vs. 3600w, 90% of the power and one and half times the coverage? No question, go with the 600s! You will be able to cover much better toward the sides of the room. What reflectors are you considering?

I would go with 4x 1000w because they produce more light and will cost you less than buying 6x 600w.

 

[randk21]

awesome video thats what I'm wanting to get goin! So you are using 4 1000hps now for that?? Hows the energy bill??

As I just pointed out in the post above, they are only 10% more power. Do you honestly think they will produce more light than the more efficient 600s?

 

[mindphuk]

As for costs, if he goes electronic ballasts he can save almost $100/ballast, even more if he gets dual 600 watters. Plus two extra reflectors.

Compare that up front cost with a 400 watt overall savings. 400w x 12 hours x 60 day flower is about $30 for 10-11¢ per kwh. It doesn't take many harvests to start paying back, if he spent more to begin with.

I'm going to air-cool them.
Haven't went to the store yet.
Still a few days away from buying them.
Gonna run two sets of three 600w in series.

Ya, those girls are under 1000watters.

It runs me about 1500 Kwh per month.

IMHO - 600's are the most efficient - but you already got 4 x 1000's - and your shit looks choice - you are set, Bra! Now the question and goal would be to replace the 4 x 1000's with 4 x 600's - then you would actually be making a diff in your energy consumption and your grow efficiency. 600's are as bright at 2 feet from your plants as 1000's are at 3 feet... using this principle, there has been a move towards smaller wattages... There is a great article on light and heat in the current issue of Maximum Yield - it is a great read and is related to your question on lighting. Again - your action looks great - nice vid!

Get Super Sun 2 or Radiant reflectors and lumatek or galaxy dual 600 electronic ballasts, you will be gold!


(the hinged glass on the radiants are so nice, easy to clean and change bulbs etc.)

What is the advantage of dual ballasts? They literally cost twice as much - so the upfront cost is the same... is it the power consumption? They have an on/off switch for each - so it does not seem like they are sharing anything that would make them more efficient than having 2 single ballasts (easier to replace singles in case of failure, right?). Am I missing something?

No, they are about 10% cheaper than twice as much

Go with what you got! Add a couple of 600's in the middle for good coverage. Lot of ways to do it. You already paid for the 1kw's.
