Highest yielding and most dense strains

There are hundreds and hundreds of strains and a ton of seed banks... and the success of any of them will depend on their genetics and the ability of the grower.... If you ask a person who doesn't know how to grow very well, they might rave about X strain because he got 20 grams off of one plant which was the highest he'd ever had... another person will have a different story about that same strain because of his level of ability and because he bought his seeds from a different seed bank... But good luck in your research!

Greenhouse Seed Co. - White Widow Sensi Seeds - Northern Lights #5 Royal Dutch Genetics - Strawberry Kush (My favorite) DJ Short's - Blue Dream

First off with anything its genetics, on top of that it depends on the training it receives, and how well it responds to that stress, if you take a look at my most recent grow in creating clones from a flowering plant, once stabilized and put back into veg eventually to be reflowered this is called monster cropping and greatly increases yields as it increases the bud ratio, can also supercrop, mainline among other techniques. Fruity Pebbles was THICK, but i messed up the cure! Your knowledge & understanding and using that to provide an optimal environment for growth that is the single greatest contributor to high yields.......DNA and light do the rest, 90% of growing problems arise from the improper environment. Good luck.
