Swampy areas are good - use buckets - google swamp grow. But we are blessed with rain here in NE so as long as you get your plants in by mid-may you are good. Yes, mid may, we are not talking tomatoes here, cannabis is tough. Dig deep, they will root and do well.
I don t grow more than 3 plants in 1 site. I use deer netting, I dont use much of it, just to protect from rabbits and other rodents, as long as you plant away from deer paths they will not bother. They will not eat buds they taste like shit to them. Also slugs and snails will not bother too much a strong, fast growing 2 month old plant. Botrytis - bud rot is my worst enemy, not much you can do.
I start with 3 month old clones, this year fast flowering Nirvana mix - AK48, Kush, Aurora, and my all time fave Bubblelicious. I use whatever soil I have, mostly composted horse shit, mixed with 10/10/10 slow release pellets, peat moss, lime - all from the local hardware store. No fancy schmansy coco peat or expensive organix, I spent like $40 on soil. I move soil and gravel in the winter on the snow. soil is not the most important, cannabis grows in anything, sun and fert is. Once I have checked on my plants a couple weeks after planting and they are doing well, I dont come back till august to add flowering ferts. I only had one rippoff and thats because I was stupid about the location.
I used to grow inside, but high costs and gilt about my carbon footprint made me look at ways to grow outside. this year i will grow 15 plants. I keep the top buds the rest I make Kief - pure trichomes, I dont compress.
This will last me the year hopefully, I dont sell, I use marijuana for my anxiety and arthritis, plus it make my life happier. So fuck the government, the police, the religious right, neo conservatives and all those other hypocrits paid for by corporations.
Peace to the rest.
