1. The Practical Aquaponics discussion forum has been in operation for the last 5 years...

    We have enjoyed giving this service free of charge however ongoing increasing financial costs of running this service is making it increasingly difficult. Up until now we have resisted advertising as a means of a revenue stream to help run this forum but it has become inevitable that extra revenue is required to run this forum.

    We have introduced a donate button to help offset the cost of running this forum. It is completely voluntary, but if you would like to donate, all donations would be greatly appreciated.

    Scenario:

    I'm an eager young man looking to take my Hobby Farming to the next level.. I've been interested in producing extra lettuce from my system to sell to local restaurants and the weekend farmer markets for a little pocket money for the week..

    I think my goals are accessible for I am only planning on selling 200-400 lettuce heads per week, that means I'm going to need room in my system for 800-1600 lettuce heads, 2000 to be safe. How much space will this take? can my dreams come true?

    2000 heads of lettuce ......
    OK...each head would take 1 square Ft..(300mm square)
    2000 square feet is equal to :
    63 - 4ft. x 8ft. growbeds....so flood and drain is out....
    Maybe NFT...
    OK.....2000 ft of pipe in a greenhouse (1 running ft. per head of lettuce).....
    Say 4 pipes with holes in them side by side (so you could reach the lettuce)....and a 3 ft. space to walk between the next 4 pipes....
    Say 4 sets of 4 pipes.....
    If you lay it out on paper...you'll probably need a greenhouse
    150 feet long by 32 ft. wide...(50 meters long x 10 meters wide)
    to grow 2000 heads of lettuce.
    Have you got that space....?
    Someone correct me if I'm wrong....

    Spacing depends on which type of lettuce you're going to grow.

    If you were to grow Oakleaf for examples sake, and you wanted to harvest them as a "whole" lettuce, then you would probably want 300mm spacing.

    I have a friend that had a hydro lettuce farm for many years, he grew a variety of the "leafy" lettuce and regularly harvested the leaves only, his spacing in this system was 250mm.

    and Daryll is about right with his measurements I reckon... that's one big shadehouse... I'd start small and see if the demand is actually there.

    Don't give up on the dream, start small and establish demand for the product, all you need is one local restaurant willing to take your product, or try selling at a local weekend growers market.

    I don't know about where you are, but here in Aust' there has been a big resurgence of interest in weekend growers markets, and you may even be able to swap some of your produce with others at the weekend markets, eggs, meat, tie-dye kaftans etc. :D

    Ask around local restaurants that specialise in local produce and find out what THEY want, rather than taking produce to them and hoping they'll buy it.

    IMO... as a horticulturist with years of hydro experience, I would say an AP system running NFT or DWC would be the most cost effective and easily managed method of producing lettuce.

    Cheers, Yabbies.

    Here's one of my (home) 200 hole NFT table, ten channels.... 6mtr x 2mtr...

    A standard hydro table would be 12mtr x 2mtr... 400 holes...

    So you'd need five of them.... min... something like the last photos of my "small commercial" system some years ago... (actually 20 tables - a breakeven hydro operation)
