Basically this is an easy process.
I am not going to melt the plastic. I will first cut the top's off, then sterilize them. Cut weep holes in the bottom, add medium, plant seedlings and store/ care. It's a poor mans nursery, but effective. The sun is so brutal on plastic, store bought planting containers get brittle and crack. Plastic plant baggies from Ochoa, on average get used twice before stretching and tearing. So, I find this method of re-using (a form of recycling) most beneficial for the long haul.
I will need for starters around 100. So, this is why I posted, for a little help from the community.
I wish I had the resources/ time for a full fledged recycling operation. Up here in the campo I pick up bag after bag off my lawn from distant neighbors. There idea of trash removal from their property/ homes is to either throw it over the wall onto my property, throw it in the road or burn it. Once a week I have to put up with toxic fumes blowing around and settling on my finca. Not good for the environment, my family, my dogs and our numerous horses.
Anyways......
Looking for containers here, any givers?
