Highest yield plant to grow?

its impossible its all down to you. A plant can yield a incredible amount if you train it for long enough and then flower it for long enough skunkle is right I have had 14z off 1 plant before. I just got 11 from 3 plants its all down to the strain and each one is different. most breeders will claim you can get 500-600gram per square meter but this is based on optimal conditions which none of us have. or know what optimal conditions are its such a broad term. I've seen some people on this site get 1kg plus per plant its all on how you grow it and how experienced you are as a grower I suppose. Having a good knowledge about growing plants and horticulture in general will increase your yields alone growing cannabis is a patience game plants can flower for much long than we allow them too. keeping in mind you don't go too far and get into self pollination territory the flowers will only increase in mass overtime as its trying so hard to get large in order to attract male pollen more pistils more chance of one pollinating. plants will only foxtail in my experience under poor light or its a certain charitaristic of that strain other strain will keep piling on the pounds and can finish with a very high yield at the cost of some potency. Also fast flowering strains often sacrifice yield to pull it off btw. The other grower is right attitude is a great place to get seeds. though there is such a variety I always recommend dutch passion always had good experiences with them. I would look into critical mass by barneys farm or and strain bread with either bruce banner,big bud, blue dream, gorrila glue there are so many to choose from but best of luck :)

Critical by RQS. Largest yeild and nice up effect, easy to grow.. but My top tip for big buds is low humidity at night. Below 50

I’ve had my largest yields ever from a strain called Big Bud. Like the name states, it produces massive pop can buds. It’s defiantly in the top 10 all time producer. Best thing about it to is she will flower in 50-65 days so very short for how much she packs on. I was absolutely floored at the size of the buds. Attitude Seeds in the UK has many different suppliers that have Big Bud in stock Hope this helps.
