16w per sq. ft... 2 lbs??

What’s good DGC, how are you growing today? Shout out to Scotty, Dude, Guru, and the entire crew, I’ve posted a few times and have gotten great responses and helpful answers. My questions today is in regards to my 5×5 – 400w flower tent. Is it possible to achieve 2 lbs. dry flower with such minimal watts?

I typically run a S.O.G. type method; whereas, I use more plants in smaller pots (in this case 16-17 in 3 gals), with a minimal veg time of about a month after clones root, and use the net to try and fill out the canopy, and as support for later in flower. Last 3 runs I’ve gotten 1.7 to 1.95 gpw. Would it be a better idea to use less plants, slightly larger “batteries” and a longer veg time in order to achieve the 2.28 gpw?

I don’t do a heavy feed, my current genetics don’t produce giant colas but rather dense golf to ping pong balls, and I have no complaints on the resin production … just want to push the yield a little more without boosters or changing anything mentioned. Big dreams I know, but curious as to the ideas and thoughts of all you growers .. cheers and happy harvests! Pics taken day 36 and 38

Good looking grow, nice, clean and full, too full to maximize potential yield. If it were me I’d be growing 6-8, 5-7 gallon pots, training the plants out wide fully utilizing the scrog net.

You’re doing a good job with your lollipopping, continue doing the same with wider plants and trimming off lower popcorn buds. Growing them straight up and tall you cannot get your lights low enough for the light to penetrate low buds without scorching the tops without too much defoliation. That’s where training and the scrog net comes into play. I am not sure that this is absolute maximization in your grow but it’s a start.

Your girls are healthy and look great. You got the growing skills, now to maximize yields. Happy Growing 😊

Sorry I forgot to include other answers, in regards to your lighting 400w from the wall is a little shy to maximize a 5×5, minimum 600w probably 800w. Two pounds in a 5×5 isn’t an issue but 2.0gpw you’re going to need more input. If you up your wattage and want to add CO2, it will also boost your yields, in order to achieve your goals. And of course with additional pot size you will need to extend your veg time to 6-8 weeks. Happy Growing 😊

Just think of the time associated with increased veg time. Most people don’t account for every variable and just look at light wattage and finished product without taking into account time. You might harvest every 2 months instead of 4. Like mentioned above extra light as your wattage is more suitable for a4x4 and then co2 to push yield. Here’s a good article.

Hello, more light would help. I would say CO2 also but I don’t have experience with it yet, I’m adding CO2 soon. Beautiful grow, nice defoliation, I’ve never gone quite that far on defoliation but next time I’m going to strip them down like yours. How do you reach the far back pots for watering? Do you have to water often after the plants recover and get bushy again?

I’ve been doing just two plants in 25 gallon fabric pots in a space less than 1/2 that size (2×5) using a pair of lights that are only pushed up to 500w for the final 2 to 3 weeks, rest of time its below 450w.
Right now they’re only 15 days old and I’ve just bumped the light up to 110w each.
I usually get between 17 to 21 oz.

This current grow I decided to change my soil as I just finished my 9th grow on same soil.
Fabric pots seem scarce for reason so the best I could find were Grassroots fabric pots at Buildasoil.
They don’t make 25 gal and 30 wouldn’t fit so was forced to go with 20 gal.
That opened up a space for a 7 gallon fabric pot so now I am running 3 plants in that space.
I am expecting 24 oz if I get my usual yield.

Of course this will take far longer in veg, I usually veg for 8 weeks.

The room looks great, but I wonder if you have chopped yourself off at the feet. That is a very heavy defoliation and yes, I have seen it done this way before, online and in person. History tells us that you will still get a nice harvest but to reach your goal, you want everything firing on all cylinders.

With the extreme defoliation, you have taken away the solar panels that capture light, photosynthesize and make sugars, which increases your bud growth. You’ve also removed a massive amount of surface area that was used for transportation (plant sweating) and that process will now slow down. But this process is what pulls nutrients up from the root zone.

So I think you might have handicapped yourself in the goal of reaching the largest harvest possible, but there are many ways to do things and I am confident you will have a good harvest, but there might have been more yield with a less aggressive defoliation.

I pretty much agree, I’ve never believed in this extreme defoliation nonsense.
The key to large amounts of big buds is use SCROG and grow in large fabric pots.
