So im not going to have a significant difference in my yeild between the 600 and 1000? Sorry if im not grasping what everyone is saying but doesn't more light = faster bigger grow?

Well there are more factors to yield than just light. My instinct says that it will be so difficult to exhaust the heat from a HPS1000 from that space that you will actually end up shooting yourself in the foot yield-wise. In a larger space, a HPS1000 gives more yield. But the footprint to run one should be a space 5x5 feet and at least 8 feet high. You could FIT one, if you can exhaust it- but that's something you need to find out.
Have you ever grown before? The way you phrase your questions about lots and lots of yield hints that this is your first time out. In that case, you will DEFINITELY want to make absolutely sure you do not have heat problems, as they are a guaranteed path to disappointment!
Edit: How long do you plan to veg the plants before flipping them over to 12/12?
How about a 400 cfm inline? Is that sufficient or are you talking about A/C for cooling?
first time out,C. Vegged for 2-3 months,i know longer then i need but light situation is the hold up. I am concerned about heat and energy,although getting the most for my money and best yeild possible is my main concern,and im trying to to do the best research for my conditions as i can.You see,i can spend $100 more and get a 1000w opposed to 600w,and this is where my problem lies.From the way it looks everyone is definitely in favor of the 600w instead of the 1000w.
Let's throw everything out the window thats been said and speak in theoretical terms. You have 2 5x6x8 room's. Exact same setup in each to the T! Same amount of plants and genetics,they grow exactly the same, same setup,same humidity and temp in the room,etc etc etc(im aware this is not realistic as nothing in nature is identical,but theoretically speaking..... One room has a 600w,the other has a 1000w.They grow for the same amount of time. Which room is going to produce a better yeild and why? Rember the only thing different in the equation is the light,everything identical
In that case, the light makes the difference.
If you decide to go for the HPS1000, I STRONGLY recommend a good exhaust fan connected to an air-cooled hood. Aim for a 200+ cfm fan!
It's good that you vegged extra time if you are only growing 4 plants under a big light in that space. I'd personally grow 36 small plants SOG on a 4x4 runoff tray in that space. You can set it up in many configurations, depending on what STYLE of hydro you prefer. But longer veg=fewer, larger plants to fill the same space. Try to train them as flat as possible as you are flowering them, and then let the buds grow up straight with no more training after the 'stretch' period is over (2-3 weeks in).
Yeh ,that's the case here pretty much. I deff have 200+cfm in mind,im going to get a 400cfm that i decided on.
But yeah its DWC style 5 gallon buckets,everything is going pretty smooth and looking good so far actually(the vegged plants are about foot half to 2 feet tall full of stems and leaves(stacked),my only concerns are getting the correct light for my setup.
You say the light makes a big difference, so am i right for wanting to go with the 1000w to get massive buds or will the 600w still be a extremely close competitor that id be better off with?
honestly I would run two 600 watt hps's vs 1 1000watt one. More lumens per watt and still easier to cool on an individual basis if going through a cool tube.Quote:
