Hello everybody How is everybody today hope life is treating everyone well

Nearly onto my next grow, using a dr120 1.2x1.2x2. Got 9 in a 1x1x2 at the mo and its fine enough room thanks 2 a bit of pruning and supercropping

I think I should be able to fit 12 in a 1.2 easily just wondering what everyone else thinks really in regards to what would give me a bigger yield 9 or 12? 9 has more room therefore could yield more but 12 is more plants so could yield more what does everyone think?

By the way this is all bein done under a 600hps (flowerin anyway) with h.p. 150 ruck extract and l.p. 150 ruck intake.

You can't really say for sure - you could either grow less plants bigger, or have more plants but keep them smaller.

You're probably better off keeping it at 9 but maybe vegging them a bit longer, or training them a bit differently if you feel that you've some extra space that you can make use of.

Yeah thats what I was thinking aswell im gonna do some measurements n ting wanna get some pictures up but my mrs has the camera

Funny..... Iv wandered this for quite some time. I go with 12 per 1.2m2 since thats what i started with and havent had the balls to try 9 incase it is a drop in yield. I think im gonna try 9 on my next to finally answer it. But thats some time away from now unfortunatly.

Little tip too..... I only use a 400w hps for flowering (which normally would be a little less light than perfect for 1.2m2), but i position a 30w fan at the end of the hood blowing directly onto the bulb, allowing me to have the bulb 6-8 inches closer to the canopy, making it almost as effective as a 600w. (sounds crazy but if you do the calculations its true)

Hello mate

Ive done 9 before (clones) with a 41 days veg in compost & topped once & it got pretty full,even had to move my oilfilled rad out aswell,heres a pic just before chop:

This time Im trying 13 with a 4 week veg (clones) untopped this time but also in a passive hydro setup finishing in 6.5 litre pots.

I rekon you could fit 16 of them pots in there,but as mentioned its all dependent on strain & growing method.

Goodluck!

p&q

That is truely a beautiful picture peace & quiet

I would only do 4 in that size growroom, 4ft sq for each plant, 2-4 weeks veg.

Ive done 4 in a 1.2 before and had quite abit of space left so I did nine n im sure i could fit 3 more in....

I've done 9 under a 600W in 1.2m2 in 6L pots, 4 weeks veg time and always until this grow i would get around 0.84gr/per watt.

Changed my reflectors this time and dropped 0.3gr/per watt.

geez mate that drop is serious,what reflectors did you have latter and before the drop?

I am about to go same 1.2 m2 and putting 12 plants in 6.5L pots,putting wide net to stop buds from colapsing in 5 weeks off flower/i am sick off thying buds and branches

Will see how it goes

Correct me if im wrong but im sure its not the amount of plants you have its the amount of light that gives you the yield.

I hear you Herbal

I wont be doing 13 again with a 4 week veg!!!!

p&q

what he said....you could put 900 plants in there makes no difference. it's dependent on your light. well thats what i've always been told anyway.

I usually do 5 fem seeds in that space, will be dropping down to 4 soon.

I treat the veg tent light as 'rent'. It runs a 400w cmh 18/6 and sometimes it's close to full but today it's only got 5 little plants that could fit into a shoebox. No matter, it does what it's there to do and no problems giving them a full veg.





How far from the bulb are the plants at the edge of the tent?

wrong , this comes up all the time .

yeild per m2 is dependant on light no other factors involved but its a fact that other things are involved ! strain for 1 (irrelevant in a plant q but still) main thing is time you do a grow with 1 plant and i'll do one with 20 , in the same time frame i'll yield many times more!

question is how scared are you of being lifted? if police make you shit your pants go for 1 , if you donty give a fuck then go 20

Interesting no one mentioned finishing pot size,that has no effect ? So is yield the same if we go with 9 plants in 6.5L pot as 9 plants in 11L pots.. on 1.2m2 under 600w? Both methods should give 20plus OZ?

and 30w vent blowing on bulb is nice idea me think i might even try it,but i gues that works only with bat wing reflectors?

I would go with 9 personally, if you can get the right size pots to fit in there, but you could probably get a similar yield with either.

I used to do 6 in a 1.2m2 tent, in huge tree pots... that was pretty awesome.

The key is definitely to veg, top and train properly

So that makes 65 grams per plant X 9 plants in 6.5L pots, equals 585 grams or 1gr/w. Somehow i think i wont get near 65 per plant

will see in 2month, ill let ya now the final score!

No wai dude, you want 11 litre pots, not 6.5 litre

Root mass is very important!!

6 in mine and it was wall to wall

Oh I just read your other post hehe

Yeah, for 12, I dunno, 6.5litre still sounds a little small to me? I find it hard to visualise though

I new it,so i need another pot up from 6.5 to 11L? It sounded a bit small to me too,but one expirienced 420 grower convinced me it good


bolox now i need to go buy 11L pots

If you're doing 9 in a 1.2x1.2, yes!!

I'm finishing in 11 litre pots and i'm doing 9 in a 1x1

Off to store tomorow for 11L buckets, at least it will give me enough time to finish neem oil treatment

thanks for setting me straith mate,its visible that i have to big holes between grows

No worries dude! Ideally you want to fill that floor space as good as possible. Root mass has a directly proportional effect on yield.

You have to bear in mind light penetration too. Sure, if you have smaller pots you can let them grow bigger, but with less root mass they will struggle more when they get bigger AND your light won't penetrate at full strength all the way down anyway...

The space at the bottom of your plants is best taken up with roots

Make sure you let them root the pots out before you flower too!

why 12? 16 plants would be more even one per sqft, reduced veg time.

I'm debating between 9 and 16 plants in exactly the same size, going to use 1000w's though.

That space is half the space i've got to hand, but currently only using that space (1.2m2)

So far i have ten plants in smaller pots, probably 4 Litre pots?, potted up from plastic cups back in veg when they rooted the hell-outta-it...

The smaller pots, 16 fits my table absolutely perfectly, four rows of four.. There is wasted pot space by doing just 10 plants but this is a test run more than anything...

Think im going to utilise all my pots so thats 16 x 2 in the near future...

Thing is since i am a table user, i dont think i've got 'root space' like you guys have. My pots are netted and get flooded regularily for bottom feeding.
I guess i could get less pots yet bigger, however need to see what i can acheive with just ten and work out what each pot can roughly bring me...

I heard someone from over the pond gets just over a keg (30 bounces) from this sort of space.. think hes got 10-16 plants too ie. smaller pots...

Roots are like a mirror, if its not happening underground, it aint happening above ground...
The most variable factor is dialing in environment, so even though you run a few pots and later run more, your enviro changes rapidly unless you can maintain it but will dent or add to your yeild, just as anything else will imo...its not a easy question but to be honest i'd stick with 9 and if you can, test 12 and see if it works for you.. then let us all know

Just to put 'gram per watt' into perspective, the bit of bud in the pic weighs one gram and there are 600 of those 2" squares in a screen covering a 4 foot by 4 tent/cab.

cool shot! '

is that a gram? x 600 holes>?
