  2. If the stats are real I only ask one question that seems to get the wishy wash answers or a flat out lie,HOW LONG DOES A PLANT THAT GETS OVER 2 LBS AT FINISH HAVE TO VEG BEFORE IT FLOWERS?Myself,I have grown my share and to get a plant to 4-5lbs in one growing season few months seems an impossible task.The revegged method seems to throw a lot of limbs and if u are good at training,have support around and all over it,then maybe I could see a plant grown inside started in feb or march and finishing in Nov being a couple lbs but hearing of 10lb tree of blue dream or seeing some of the trees people grow I just have that one simple question..and cannot get a strait answer most times.A 55 day flower is great but it must have grown for quite some time to get enough size to have an enormous amount of bud in 55 days after veg and being put outside in june,or 12/12 in a place with 100sq ft a plant floor space with a 15 ft ceiling

    Reply
    • Start with a 6x6x 1ft deep pot(8x8x1ft is even better but its a pain come harvest) feed your baby(that you started indoors in feb/march) well and on time, top when ready and strip out all the larfy bud about halfway thru flower and THEN you will start to see 5+lb plants. Good luck

      Reply
    • I’ve done 1040g on one plant indoors with dwc on an average strain. That was a 38 day veg and 9 week flower. It’s about genetics and environmental control. I ran led and rdwc chilled and ro water.

    • Check it out bro if you want a 10lb plant than you need to start vegging like yesterday !! Finish around 2nd week in oct … If you treat her right it can happen.. I’m doin the dam thing as we speak ️ happy growing sir

  3. High!
    I think Big Bud is the highest yielding strain.
    One more note to you, this is the Incredible Bulk from Dr. Krippling.
    It might not get a medal position, but in many ways better than the other strain. It is a high-yielding and large-sized plant, tolerant of all pests and although blooming late, produces an explosive miracle. Avoids pollination by wild and industrial hemp. It has great hybrid properties. Hassle-free, but thanks to high calcium and magnesium supply.

    • Ohhh Oklahomans have and had good genetics but our weather changes more than a female tryna impress at the club… So with humidity it’s a struggle and dense buds can get “bud rot” so I prefer to create and work on strains that can thrive here … we’re not even 2 yrs into legalization

  4. Very informative with a good choice of high yielding strains. I live in a very wet region in the pnw, and I’m leaning towards super skunk for a both inside and outside grows. I can’t wait to try it out and see what happens. Who wants a bunch of bud if it’s not high quality so super skunk sounds good to me.

  5. Are these estimated yields by experienced grower? Or is that a minimum and maximum.. seems to me little high numbers. I’ve gotten 1.1lbs off my white widows outdoor last season but I’ve yet to see kilos off singular plant.

    Reply
    • It’s all estimated amounts. A lot of us can really wring the weight out with the right seasonal conditions. That 4-5lb per plant mark is in areas perfect for growing and of course outdoors. I get the about 1.5 from a single WW indoors but I control it’s whole environment and I have limited space. My best yielder was a 4 plant run in 4×4. Seedsman Big Nugs Fast. I vegged and trained vigorously for 6 weeks and she banged it out it 7 weeks bloom (including transistion). Final weigh -in DRY was 2.96 lb (7 gallon Final size air pots, remo nutes DTW (30%+ runoff fed daily, FloraKleen Flush bi-weekly) 65% coco/ 30% Perlite/5% Basalt, CO²) and Bigs Nugs is just their variety of big bud when you look at the genetics. (I’m not plugging seedman at all because it’s all pirated genetics. But they are good genetics. Alaskan Purple is a beast outdoors and it’s almost never in stock in the late winter and through spring for this reason. A couple missing here are: Julie’s Cookies from Dr. Krippling,(she produces some big ass colas), The right Pheno of Super Lemon Haze from Greenhouse can seriously produce. (I’ve personally seen 3lbs from 4×4 consistently from a friends clones) TH Seeds Heavy Duty Fruity is another that will break 600 g/m² with the right care although she is a bit more finicky on her nutes that the last two.

  6. big bud is the one for me reaching over 3 meters tall is one big plant this is in Tasmania with 2lbs easy and easy to grow 400 litres grow bags and plenty of water and feed all the time

    Reply
    • My big bud grew to a 1.4m height. Grown in pig manure in a 300 litre volume blowhole in limestone rock. This plant yeilded and yielded and created branches to be propped and tied up everywhere. Now this plant yielded 5 and a half pounds of over manicured bud. Trimmed differently I know conservatively it would have comes in at 6 pounds all told. South Australia turned on a beautiful finishing season. And many a person raved on about it for an evening smoke. Cheers
