Would 30 gallons of a soil consisting of (below) bring 1 pound per plant? Also how big is a 1 pound plant? Any pics? Final mix- 500 gallons (67 cu. ft) 1/3 peat 1/3 perlite 1/6 compost 1/6 ewc 4.25 gal. Lime 20 gal. rock dust 4 cups per cu ft (264 cups) 80lbs of epsoma garden tone 2 cups per cu. ft = 132 cups (8.25 gallons) 66 cups of kelp meal (4 .25 gallons)
My grow isn't shit compared to a few of the fellows on the 2012 growers challenge thread. But yeah, you can certainly pull a pound per plant with that set up, but you will need to give them lots of space and lots of sun, top a few times etc. My pounder plants were different heights and widths but they need to be big. Plant them at least 10-15 ft apart at the base to leave room for them to bush out. One of my plants was 10 ft wide and 7 ft tall. That plant yielded 2 lbs. Another plant I had was 10 ft tall and 7 ft wide. I still haven't done the final weigh in on that one yet but I know it broke the lb mark too. So both of those plants were about 70 cubic feet, just one was tall and one was wide. I prefer growing the wide plants myself. The tall plant was hard to are for and had less nice tops and more popcorn buds. Anyway, my smallest plant that yielded a pound was about 6 ft tall and 5-6 ft wide. It was smaller but I let it grow longer so the buds put on more weight. The only thing I can think of off hand that I would add to your soil mix is some alfalfa. It's supposed to be like an organic super thrive. Great for root growth and a good source of nutrients.
My largest pull from the smaller smarties I had was the pound and 10 ounces from my unknown strain think it was blue cheese or very similar in a twenty gallon pot with fully amended soil.
Ive gotten a pound indoors in a 7gal smart pot... 6 foot tall plant - super-topped and super-cropped to perfection is key
Here some pounders last year [ame=http://www.youtube.com/watch?v=buzYHgT5hb4]C 99, Sour Diesel, White Widow, AK 47, American Dream, Dogshit, Monster Backyard Grow #5 2 - YouTube[/ame] Some of these were in the ground native soil with on bag FFOF and perlite. Native soil does the rest. [ame]http://www.youtube.com/watch?v=hQRpVHe5sis[/ame] [ame]http://www.youtube.com/watch?v=hQRpVHe5sis[/ame] Here is some this year. They were not full one pounds this year though. 1/2 plus average. I started late though like on June 29th from clones & teens. 27g pots with FFOF soil and 30% perlite. FF treo of ferts. PH'd fert water to 7.0. Thats my basic grow. I did prune the bottom out this year though. Size wise it was perfect for me. Those vids above with 60 feet of plants was way to much work. Next year I am growing only 6 plants. Or maybe 6 plants and 6 Autos. [ame=http://www.youtube.com/watch?v=NFgwKYKJNaw]2012 Grow G-13 Sour Diesel American Dream Lemon Haze & More - YouTube[/ame]
