what method of vertical for better yield

[dazzerx2000]

Help me decide please,

Hi sorry about the long explanation but try to visualise what im getting at. Im using 5gal circular pots vegging my plants till there 3ft tall then flicking to 12/12 What method should i hang my lights for maximum yield from vertical plants i have two options that i cant decide upon.

1. Place 6x 3ft (in veg) 5-6ft(in flower) plants around 1x600w hps in the middle moving onto 2 later in flower and have another 2 hps hanging on the outer sides of the plants where no light reaches.

or

2. Place 12x 3ft (in veg) 5-6ft(in flower) plants around 2x600w hps in two circles of 6 plants with lights in the middle moving onto 4xhps later in flower. SNAP the bud sites/branches on the sides where no light hits the plants because the bulbs are in the middle with the plants circling them, fold these branches into the plant and when the plant regenerates they will hopefully grow to the light???


Hope that makes sense what would you do in this situation. thank you for any help received

anyone??? the question can't be that complicated?

I would stack the 600's around 10 or 12 plants and see what happens.

Have a look at superconductors vertical grow diary, i'm sure that'll help you if you haven't seen it.

thanx for the replys following up on the info proided what would you say then about the shaded side of the plant what should i do about it.

 

[pine boy]

That depends on how the plants grow.Train them forward if the're long enough and or suppliment with some dangling 23-27 watt cfl's.
I would also look at supercropping before I try a screen.Thats me tho

Put mylar on the walls

 

[dazzerx2000]

thanx may i ask is diamond Mylar better than normal Mylar? as it doesn't crease ect

pine boy breaking the stems is supper cropping or a form of it ill be basically forcing the stems on the unlit side of the plant forward if they have to snap to do this then all the better as when the stems/branches heal they will be a full 180 heading in the direction of the light. The only reason im thinking of using a screen like superconductor is to stop the plants potentially touching the 2x600w lights and burning the buds im still looking at the link bens lab provided but ive decided already to go with a small gauge screen size some good info in that thread.


Ive started to notice ive wasted allot of time and money on horizontal kit but just about every new grower is steered in that direction it'll be good to try a new method and get rid of allot of heat as well, had to start somewhere i guess. thanx for the continual support.

 

[pine boy]

Yeah Dazz I wasted $$ on my reflector.I knew it as soon as my 400 lit up.I kept it on for about a week.
As far as a screen goes,I will suggest you try a grow without one but use most of the other techniques similer to a scrog grow.Like not moving your plants or rotating,light trimming of fans that are in the way.
I dont use mylar so I really dont have an opinion but white flat paint looks good,last long time
Good luck Dazz

 

[og kush]

i hate mylar. i use flat white paint. reflects better imo.

 

[Bush Dr]

i hate mylar. i use flat white paint. reflects better imo.

If that's true (which it's not) why can't you see your reflection in flat white paint when you can with mylar???

Flat white =80%
Mylar =98%

Dazzzer .... use a screen for your first run and don't rotate your plants or the buds will end up airy

Now i know a fan under the bulbs is a good thing to have but what about oscillating fans? in traditional horizontal grows you always have oscillating fans to help with air movement should i keep using them?

One problem that i can think of is while the fan under the bulb is pushing air up over the bulb and to the ceiling, the oscillating fan might blow this air onto the plants if you get me as it rotates from left to right.

I don't see how the plants get allot of air movement without the use of oscillating fans thou???

 

[dontae1000]

vertical circular coloseum is the best.......and concerning mylar or flat white paint, whatever is easiet and cheaper, the inverse square of light is everything, if u think mylar or white paint or the 7 pecent diff between them in relfectivity reflecting light back at your plants from like 3 or 4 ft away is going to make a big differance dream on., use on of them for sure, but dont expect miracles.

 

[Bush Dr]

The fan under is there to cool the lamp, ideally there should the a straight line through the fan/lamp/exhaust .... the fan may have to be suspended from the screen to keep it cool

Air movement is partially achieved by the vertical draught moving air, but I use a 6" fan in each corner of the cab blowing straight up ..... you need a good extractor fan

 

[dazzerx2000]

hmmm i think i see what you mean im going to use a 7inch fan rated at 740m³/hr for under the cage its designed to work at 180degrees angle, perfect for blowing over the bulbs, the heat from them going to the ceiling will be caught by a acoustic 250mm extractor fan rated at max 1380m³/hr with a similar fan 200mm version for intake. Both fans will be run at max speed unless needed otherwise i understand this is over kill for 2x600w but im buying big now so i can multiply the setup in the same room numerous times if it works out good.

The room itself is 4mx4mx3.5high and ill use one oscillating fan in the whole room to move air around. Unfortunately i wont be able to get a clear line of sight for the extractor fan from the bulbs the extractor fan will be placed very high in the room at one end but due to hot air rising i don't see there being a problem at all.

 

[Bush Dr]

dazzer ...... you want to make a false wall and get a rectangular space which those 600 lamps will really shine in ....... Prawn Connerys cube is pretty much what I have

If you want to make use of that height I'd put the lamps end to end and build a 1.2m sq box with the extractor pulling straight in the middle (duct it, easy to move then), line that with mylar and you're looking at 40+oz every cycle, more as you tweak it

Is that the sort ot yield you're after?

 

[dazzerx2000]

Bush Dr yeh 40+ is deffo what i would like to see the more the better id be happy with anything to be honest max ive had from horizontal grows is 26.5oz so looking to improve didn't think about boxing things in with a fake mylar wall to tighten things up might have to consider that sounds good to begin with till i expand out into the space.

I wanted to set the room up with a bigger grow in mind hence the extractor being in a place that'l cool the whole room not just the pending grow if you get me but i really should just make the extra effort and move things around after the first grow after all the yield will be better wont it. Im looking at mimicking superconducters grow instead of something like what Prawn did as its just really simple and im probably the worst DIY'er about also i going to grow in compost instead of coco or hydro (what i should really be using) because of the frequency of watering's and less maintenance as i work ect and have very little time and watering every 2-3days for big 5gal buckets suits me.

obviously yield will be lower and i will need a longer veg time to but im hoping to offset some of that with a separate veg space in the loft. Ive tried hydro ect and was good at it till i started working more hours its the simple grow in the end that will win with me due to my schedule.
