2 600's 1 1000 HPS

[Laser_Face]

I am growing in a 4x8 tent. My plants are in a perpetual SOG moving from left to right across the tent (new plants arrive on the left and finish on the right side) every two weeks.

My question is how would you position the lights in order to achieve the maximum output given the photo period and when the plant needs the most light? Would you place the 1k in the middle the beginning or the end of the flowering cycle?

Thanks

you dont need the 1000watt hps at all. In total you have 100watts per square ft when you only need 50 to 60 watts per square foot i say drop one light.
600 1000
600 600
up to you.

Agree with Craven ....1 better dump the 1Kw add another 600w, less heat more lumens ...baby it's always in the Lumens, did I say U can get closer?

according to my calculator 1,200w÷32ft
=37.5 w/ft

2,200w÷32ft
=68.75 w/ft

68.75w/ft is certainly not over kill it's a pretty nice number in fact.

well i used to use 3x1000w hps over a single 4x8 so I do not think that is too much light.
regardless of what stage you put the thousand watt light over I would definitely put it in between the two 600's.

but I think that's a decent layout for your stages as well for the plants to start week one at one side of the table and move it's way across the table. that way it's got the least amount of light at the beginning and end of flowering and the most during the middle.

If you really feel the need to add the 1000w to your garden I would recommend that you use the 600w and side lighting hanging vertical and I would use the 1000w over the top in an xxxl hood with NO Glass. As long as you have the proper ventilation and cooling heat shouldn't be an issue. Lots of factors play a key part in light placement , such as strain, indica or sativa by you using the SOG the plants should be short and I(personally) would defoliate before placing them in flower.

Sorry mate i was to pissed last night i divided 3200 by 32. You can go A or B, if you do run into problems e.g heat drop a 600 that would be 50 watts per sq ft which is still good. if you have the head space you can play around lamp heights as well.
thanks Lammy.

Guys thanks so much for the quick responses! I'm gonna run the 1000 watt in the middle. Seems to be the consensus... I'll post some pics when its all done. Keep an eye on my F-13 from dj. should get interesting...

Thanks again!!

Thanks reaffirmed my thoughts!

pictures please. let me learn something tonight. how are you growing? i've seen 2, never seen 3, but if it's been done i'm late to the game. i stand corrected... just youtubed it. let me ask you this, per 1k i've magic numbers for me are 1.5-2lb. So having 2k in a tent 3-4lbs. So how much are you planning on getting with the extra 200w? And is it worth it? Might be more efficient to run 2k, initial investment might not be the time, but as all things bought, they pay for themselves in the long run.

I would go with choice b. Or do what tdotellis said and use the 600's as vertical side lighting. I run a 4x8 table myself with two 1000's over it. I wish I could use 600's for side lighting, but the summer time and power costs are stopping me. I have another table that's 3x6 that I use a 8 bulb t5 fixture and it works great. I really think most people underestimate the benefits of supplemental lighting. In your case the 600's are supplementing the 1000, that is if you go with choice b.

I'd like to see pic my self as I'm doing SOG soon also.
Do you have mothers? Or do you just take clones from the plants on the right hand side?

Agreed. A 1000W bulb over a 4'x4' area is 62.5W/sq.ft, giving excellent results.

My experience is obviously much more limited than many here, but I'm of the opinion that intense lighting in that range greatly promotes growth & speeds maturation somewhat.

Dunno that it's the point of diminished returns for commercial growers, or that even greater intensity would be beneficial. Growing for oneself & close friends, the cost considerations of a business aren't necessary. Slight inefficiencies of process are not much of an issue.

3x1000 on electronic digital ballasts with dim and boost controls. i prefer solis tek matrix as you can use a remote control to adjust the wattage. in my setup, i find it hard to adjust my ballasts (they are out of the way).
having the ability to run 1000 watt MH bulbs is an advantage during early veg and late flower. you can still run 600w HPS bulbs on the 1000w ballasts and the price is not much different.

I'd put the 600 on the early side and let the 1K penetrate for increased bud maturity deeper into the canopy on the finish side.

 

[BCNeil]

Have you ever tried something like

600mh 1000hps 600mh?

 

[gus738]

this is indeed good as i plan to do 600 then 1k hps for flowering and if i have money ill get the 600 vertical as side light.

@BCneil. That is exactly what I ended up doing 600 1000 600. I'll post some pics later when the lights come on. Seems to be working well so far.

peace

thanks in advance bro i would like to see your pics
