I have grown GDP and the purps with no hermies but i got those in clone form from the club... I am growing out sharksbreath by dna now- i highly recommend for beginners and pros. high quality and low odour variety- Allegedly the genetics are jamaican lambsbreath and great white shark anyways i got four females and they are top shelf sativa-hybrid quality also dinafem white widow is easy grow and very forgiving. If you are still looking try ace seeds or ******s you cant lose with either and ****** gives bomb freebees.
big yeilders are a tough outdoor grow. 2 kinds of plants yield big= plants with big fat donkey dongs which mould and catch every disease blowing on the wind or the wind itself destroys the plant when budded.
the other type of plant that yields big are big plants. Early skunk or early pearl get huge and yield a lb or more. Kc33 yields big because it gets 12' tall.
The second category of plants performs much better outdoor. Strains like critical mass, himalayan gold, kc36 - with huge buds are hard to grow outdoors. caterpillars/ pests/diseases.
Dinafems Blue hash yields well. ".Mango" from Kc brains would work well but its not feminized. Brains breeds for outdoors and mango has huge buds, doesnt mould easily and finishes early. Its rare in that respect from my perspective. Even it has to be staked heavily or the wind ....
I make a copy/paste of my comment in the "best yielding strain" thread:
I can tell you.... Ace Orient Express has an amazing yield.... forget big bud or chronic, ak47 or whatever.... last summer outdoor they yielded more than any other. Over 300gr each of em in 40l soil. Superskunk and shivaskunk high yield phenos planted the same time, which are pretty nice yielders, didn´t even reach 200gr the one most yielded, never had other strain even come close and I´ve tried many. Some other strains i had at the same time didn`t reach even 100gr with the same setup. I had a branch of an OE plant that almost yielded the same as Paradise seeds Ice cream (very potent cerebral smoke Ice Cream by the way) Supervigorous as hell aswell and good structure.
I´ve heard she goes well indoors too, but haven`t tried and that the regular seed form is higher yielding than the fem version.
Greenhouse Seeds' strain AMS was the only plant that didn't get any mold. It grew among 2 other strains , Dutch Passion's Holland's Hope & Paradise Seeds Rox, which are mold-resistant.
The weather conditions were perfect for mold. Each strain was flowering their last 30 days.
