I like like 9- 3 gallon pots of coco in a 4x4. Doesn't require much veg time to fill the space.

I agree, this pic is 7 days into 12/12. These are in FFOF + 25-30% perlite and topped once. No further training required, I'll stake the mains up in a week or two.

Grow buds not branches. ;)

What quantity do you think you`ll get cramping 9 in 3 gallon pots in such a small space?
I did 2 pineapple chunks in4x4, 8 gallon pots under 400mh veg then two 600s hps for flower and i got close to 2pounds.
Next run did one PC in a 13 gallon pot, same lighting as the above and pulled 2.5p.

PS: that is just running A and B nutes only. No other additives.

Each to their own. This might not work for you, but sure did for me.

It all comes out about the same, the more plants you use the less veg time required. I used a 4x8 with 18 plants in it for years and hit between 4-5#.

Less veg time, equals more crops per year in most cases.

I've since moved and have more space and plant count limits. I have to grow bigger plants. Turns veg into a lot more work. Before it was clone to cup for a couple weeks then into a 3 gallon for a couple weeks and then flip. Now I'm having to get veg plants way bigger and grow em for way longer, and on scale that's a lot more work and takes up way more space. If plant count limits weren't a thing I'd be running hundreds of plants with barely any veg. But that being said i just hit my best yield to date off big plants, over 3.5 per fixture. But I'm confident I could hit just as much or more with small plants and cut out a lot of work.

Time is a factor of efficiency. So you have to make the equation such that all factors are weighted appropriately based on your value of importance. So one could make the case for 1 per square foot (64 plants) in 4” rockwool in an ebb and flow table, which I would say gives fastest turn around and greatest yield. And on the other hand 1 plant total in a 25 gallon soil pot. Slowest turn around since you have to take time to scog it out but maybe for some the simplicity of 1 plant and no pumps timers tables etc makes it the choice to select.
That being said I run 1 plant per 2’x2’ in 3 gallon coco DTW hand watered.

So if it were my tent it would be 4 plants. Seems to be a consensus in that as being a sweet spot.

I'm not understanding how 1 plant is more work than multiple.

I've grown 32 plants in a 4x8. It was a pain in the ass. I now do 1 in a 3x3. It's much easier. Granted I don't get as much yield in that space but it's almost a quarter of the size smaller. I dunno.. much easier imo.

The thing that makes me nervous about that is messing up the plant. I would say min 2 but I like the idea.

Ok, I had to bump it up to two plants in the 4x4. Some unknown soldier sprouted in an old pot and grew, so I pruned and bent her and tucked her in:

... I still think that 4 plants in 5 gallon pots fits about perfect into a 4x4 but that's just me ...

Totally on board with ya D.D. I'll put 2 plants in my 2 x 4 in 5 gallon buckets. Each plant in a 4 square foot area provides good air movement with no overcrowding. Yields are just under 1 lb each time.

Personally not a fan of managing too many rootballs.

One plant would have to veg for a long time in order to get the structure of many plants, a monster! Veg for 4 months or more! Then ScrOG or tie it down to fill up the whole 4x4 tent then flower! Where you can take 9 veg for 1 month and flower done

the T4 is about 203 cfm... too small for your area. i have 1 in my 4x4 and should have bought T6... 400ish cfm.

I've made that mistake more times than I can count, I've just got to the point where I buy a size bigger than I think I need and use a thermostat or speed controller depending on the setup.

Why do you feel you need a bigger one? I am just curious as I have a 4" in a 4x4 and I get negative pressure easily at half power.

It's under an HLG 600 Rspec set at 50% with distance of 30" for veg. Slowly turning up now during second week of 12/12. Its at about 420 watts now and I will keep turning it up a bit every day until it hits 600 watts. There is also an HLG UV bar attached which I will turn on when stretch done.

Is there a reason you're waiting until after stretch to turn on the UV?
