Two 1k lamps or four 600 watters?

RichiRich · Nov 4, 2010

Which set up would you chose if you wanted to grow around 30 - 40 plants?

Don't the 1k lamps have more effectiveness, more lumens/m² ?

Also, is it true that instead of having lots of plants, I could get the same yield just by having less plants and using more powerful lights?

Thanks

TRUST ME!!! your going to get the same response from everyone

Yeah, that's not even debatable.. Anyone that knows anything is gonna tell you to run the 600's, and actually they are more efficient than the 1k's.

EDIT: As far as number of plants and added yield, you will get a better yield off of more light, but you would need to veg the plants out bigger to gain the potential of the added light.

Depends on what you are trying to do. Little to no vegi 600's/ If you want 4 or more weeks of vegi then 1000 for light penetration

RichiRich · Nov 4, 2010

Ok - so you're saying I should get four 600 watters and spread them out - I see.

However, how do you explain the penetration of the canopy and the lumens/m² ? I can't see the logic in this - a 1000w should definitely be more efficient... no?

And would I have to cool the 600 watters as well? I had one of them in my last grow and it was pretty damn hot... I don't see how four of them are going to run without cooling...

Wouldn't the problem of the 1k lamps be solved by just cooling them? I could bring them closer to the plants in this case....

I am thinking of vegging for just one month - I want this op to run like clockwork, producing a shit load of weed with both a veg and flower room.

just because each 1k's produces more than each 600 watt dosnt mean 2 1k's is going to produce more lumens than 4 600 watters...

think like this

each 600 watt produces 90,000 lumens

90,000 x 4=360,000 lumens!

(1000watt) makes 120,000 lumens

120,000 x 2= 240,000 lumens

with the 4 600 watts your getting like 100,000+ lumens more than the 1k's and you can put them closer to the plant!!

Ok then - I'm convinced

Thanks for the advice.

What about cooling - is it necessary for the 600 watters?

RichiRich · Nov 4, 2010

Buuuuuuuump!!

marsellus wallace · Nov 4, 2010

if you put cooling systems on the lights you can put them closer to the plants but is not really needed if you have a stable environment, (meaning you have adequate cool air to keep your area from 70-80 degrees) air conditioner ,ect.

Ok, because honestly - I have no idea how I would set up a cooling system for the lights... Maybe the money would be better invested in ventilating the WHOLE grow room instead.

Also one thing - if I put the lamps closer, doesn't that narrow the spectrum of the light reaching the other plants? Or should I bend the reflector upwards on all the lamps, like I did on my last grow...?

Thanks

depends on your temps outside. if you can pull fresh winter air cooling is not needed, just get a decent exhaust.

is money an issue 4 600s will cost almost double than 2 1000s i bought 6 1000s cause i couldnt aford 10 600s

this is true good point 600 covers 3x3 or something and 1000 covers 4x4 so a 12x12 room would need 16 600s and 9 1000s thats and extra 7 lites that are only 60 or so cheaper.

George cervantas say 600s are optimal.
I run 1000s cool fall and winter air and chiller in the summer.
coolind i think is a huge positive and u can t at the end of the cooling line for an exaust vent just put a dampner on it to keep most of th ecfm comeing from the lights.

LIBERTY MEDICAL · Nov 4, 2010

you could light your 12x12 with 6 1000s and have plenty over lapping light that a light every 40"s and 1000covers more like a 4x8 area
i have 5 in a 8x12 and its super bright

Yea well if I had a 600 w for every 8 plants, meaning 32 plants for 4 600watters - I think that would do that job, wouldn't it?

Cus Buying 4 1k lamps is a bit too expensive and it will surely be too noticeable on the electricity bill.... :\

LIBERTY MEDICAL · Nov 5, 2010

pay your electric bill and the power company wont say shit they dont care as long as you dont steal power they just wanna get paid.

people are all excited about there 600s but when my homie came over and saw my 1000s compaired to his 14 600s he about blew a load
just sayin dem 1000s have there place

LIBERTY MEDICAL · Nov 5, 2010

o and here its about 40$ a month per 1000watter

withoutAchance · Nov 5, 2010

I think a 1000 is good for 4x4 or 9 plants in some close arangement of 4x4 altough nthe supplimental light or the light right out side the 4x4 is still better than teh 600s but people swear by 600 i dont get it

Yea beats me.. Everyone is saying to get the 600 watters instead cus you can position them closer to the plants... But if I cool the 1000 watters, I can do the same thing, can't I? Now wouldn't that be better?

Oh well - guess we'll have to figure something out.... Maybe two 1000 watters in the middle, and a 600 w on each side to compensate.

What do you guys think? What would YOU do in my position?

Thanks
