I just wanted to no what sort of yields per sq ft are achievable and what you get then ppl could work out what space they would need for the amount of bud they need and it would make me be able to see what would be the max light for a small space and still be worth the runing cost

[Mr THC.]

I was thinking more smaller iv got 4 sq ft wish I had 30 sq ft

[Mr THC.]

Yer I no but was asking what the max per sq ft in terms of yield not light

[Mr THC.]

Ok let me put it like this what's the best yield per sq ft with the environment bang

[compostverte]

Within reason it is down to watts .

A 250 watt HPS would work nicely in there - with good ventilation there are people here who can get 250 grammes - or 62.5g per square foot if you prefer. - that's a gramme per watt which most people struggle to get from more efficient lamps ...

Ventilation is key - you want to almost emulate a wind tunnel in such a confined space.

I've been very negligent in that respect, but I haven't had less than half that most of the time I've been growing ...

yer i no that a good grower in a dild in room can get a gram per watt but i have a 400w so wanted to see what ppl in the micro section can pull in a small space so thats why i was wuondering what the best sort of yield per sq ft

I guess if you have 400w and you can get a gram per watt then your DR60 has 4 sq foot which means an optimum of 100g per sq ft.

It's the gram per watt thing again. Regardless how many sq feet you have the light and environment dictate the yield. The yield per sq ft is relative to the watts per sq ft.

oh ok i was just thinking that you can only get so much bud in my tent so would have thort that thear would be a max sorto of number

no, it's not, there's something called diminishing returns....

i.e. more light only equals more bud up to a certain point, there's not a chance in hell anyones going to be pulling 100grams from a square foot unless they've got a good co2 dosing setup.

i grew with a 400w in approx 4 square feet, and my best yields were around the 2.25 Oz per foot i.e 9ish Oz from my 400w, never managed 250g from a 250watter in the same growcab

with co2 i could get around 15 Oz with a perfect grow, (well actually that was about the yield from my best grow from that space) usually got around 12-13

thanks scraglor so it looks like about 9 is the max my grow can praduce maybe ill look at a dr90 after this grow
