Discuss Trampo's answer to: Has there been a successful vertical farm in the USA?

Any plant that dangles vines would work.  Out here we grow wheat and potatoes. 

We get half again as much wheat out of an acre as they do in Canada.  We buy "sludge pellets" from waste treatment centers all over Washington and spread it by aircraft after each harvest.  Just let the rain and snow push it into the ground and the next season we come back with bumper crops with the land we were planting already.

We use blood meal, bone meal, chicken and steer manure on our potato land.  We have to put just a measured amount on every acre and we come back with better spuds than you get out of Idaho.  The sludge we get comes in a powder or pellets.  Buy pellets if you are going to rototill it in, or buy powder if you want to mix it with water and spray.  Either way it works great.  Yeah, that is what leftists call "chemical fertilizer" but it works and it came from us.

The only ones that come back with poor crops are "organic farmers" that refuse to do anything like the professionals do it.  One gal from some leftist liberal college went to a farm town in Kenya and had the people trash all their home grown produce cause she thought some farmer might be using chemical fertilizer miles away.  That is why they went hungry -- cause some leftist college type got a word in edgewise.

That is all college ever got anybody.  Talk about uneducated.
