Help me decide...new room

Going to be doing a 4 X 8 space (for flower). Currently i do a 4 X 4 space and have one 600w and have pretty good results. Should i do:

1. 2 600w
2. 3 600w
3. 2 1000w

Those are the 3 options I am considering. Will three 600's be a lot less electrical than 2 1000w since they are more efficient? Is there other options i should consider? Light movers? thanks guys and gals

Just thought of option 4 that is kind of a compromise. two 750w's! yeah

I would do the 2-600's. As they say more is beter. The 600's are the best light output for the power used the 1000's have more lumus, heat and power cost. with two light going of any size you'll be dealing with alot of heat.

put two 600 watt hps on the sides ans one 400 watt mh in the middle, im in the same position you are,
got the same size room and just dont know what i wanna put n there

lol I got the same size room and run one 400 with a few cfl's would love the 600's but just 2 the 400 would go to the veg room.

I use 3x3 trays.. and I love my 600s...

But if I was using 4x4 trays.. I would go with 1K...

I actually vote for 1x 600w per 3x3 area... I prefer 600s to 1Ks by far...

Opinions based on experience... journals in sig..

Maybe i can swing a 3X9 and put 3 600's. - hmmm, i know im not doing 1 1000, or 1 600. Im doing more than that for sure

Im setting up my new room with 2 1000w HPS Magnum XXXLs per each 4x8 tray - after a lot of research , trial and error !

im in the same size room and have a 1000.. im gonna get a light rail.. less hydro and to go get 2 600 would be too pricey seein as i already have the 1000... 2 600's would be ur best option if u have the $$$ to invest and good circulation for heat issues

Al B. Fuct... https://www.rollitup.org/hydroponics-aeroponics/6592-get-harvest-every-2-weeks.html uses 1K per 6x3 (roughly) area... and pulls a pound every two weeks...




I adapted his method with 600s... and when fully operational gave me an once a day...

about the same results as Al... just broken up into a daily harvest...

Here's a shot of it in full swing...

I am not worried about $ or heat. I am going to have great venting etc. I just want to maximize my light, and worry only about electric bill prices getting to high. 2 600's would be good im sure, but maybe i can do 3 600's and get a lot more in that area. Things will probably fatten up a lot is what im thinking with the extra 600 (all while being more efficient and a couple hundred watts cheaper to run.)
