The first principle I’d like to present you with is the idea that you need to grow something your already know and already like. This might sound very simplistic, but seed catalogues and nurseries can make even a vegetable you don’t care for sound irresistable! (Heaven only knows I’ve fallen for it more than once.)

If you have a 20×20 foot plot in the ground you can afford to take a chance, but when you only have a small amount of room, go with a proven winner that you know you’re going to enjoy.

Also, you need to adopt a very Stephen Covey idea and begin with the end in mind. By that I mean only grow vegetables or herbs that you not only like but you actually know exactly what you’re going to do with. to make my point, just think of zucchini. Every year at the end of the gardening season when abundant harvests are generously distributed to friends, family and neighbors – what gets handed out more than anything else? Zucchini! Why? Well, because almost everyone plants too much of it and almost no one knows what to do with it! Do you?

Vegetable gardening on your balcony deserves a bigger reward than harvesting your crop and then watching it go bad when you realize you really don’t know exactly how to cook or preserve it or what to eat it with. I did that the first time I grew Thai Basil – which I love and NOW know what to do with.

Think it through!

I pulled the beefsteak tomato, green bell pepper, Brandywine tomato and flat leaf parsley – each in their own one gallon pot (which is only 6″x 6.5″high) from the planter they shared with a single gravity feed valve.  Of all the hydroponic designs I played with this summer this simple configuration – 4 pots in a single tray, with a single valve, from a single purposed nutrient reservoir- was the most successful.

when I pulled the plants from the pots, I was gratified to see the kind of solid mass of roots that you’ll be shown in any picture that demonstrates what a root bound plant should never look like.  But since I had no intention of either increasing the pot sizes, planting them into the ground or extending the life beyond a single growing season the solid mass of roots was good news to me becuase the purpose of the exercise was to confirm that – You Can Grow a Full Sized Tomato or Pepper in a Six Inch Pot!

OK,  so neither the beefsteak tomatoes nor the peppers will yield Fall Fair Blue Ribbon sized fruit ( yes they’re fruit!)  but they will yield a steady, generous crop of food – and you can do it in the lowest maintenance container garden that you can imagine.

Since I’m about the worlds worst artist,  I won’t be sketching out the designs but I’m going to create a PDF with photos to show how to make these gardens.  I hope that for anyone who would love to grow their own organic vegetables and herbs, but don’t have the space to plant a garden – these designs will set you along the road to your first harvest.

I’ll post information about the designs here – and probably post the PDF on my ecommerce bonsai site – Zen Garden Bonsai.

Oh – the flat leafed parsley is actually still good until a hard frost takes it out – here’s a shot of what it looks like.

First it was a matter of getting rid of the overly complicated mixing and balancing of nutrients that are an inherent flaw with traditional hydroponic systems.  At least they’re a flaw if you want to get regular consumers interested.  Then it was about ditching the reliance for electricity – and luckily both of the first two problems had the same solution.  I thought the gravity fed valves were my answer but now I’m not so sure.  I think they’re overpriced and I can’t seem to do anything to bring the prices down and they are still a mechanical element that is subject to a few hiccups.

If it doesn’t work flawlessly, it can’t be foolproof and I want foolproof.

The second season is starting and the new lettuce garden is still hydroponic, still small space, still organic – but this time it might also be foolproof, too.  You see, I’ve ditched the valve for now and I’m working on something that is sooooooo simple – if it works – it will take the container and balcony gardening world by storm.  On the other hand – maybe I’m about to find out why this technique hasn’t found broader adoption.

I’ll let you know.

BUT – Everything and I mean everything that relied upon my hydroponic watering system including tomatoes, herbs, peppers and all the salad greens were in perfect condition.

I’m struggling with an affordable way to bring this system to market.  The problem being that I’m just too small to buy the volumes that will command a great price so the cost of goods will be ugly and unless I want to market these for free ( or worse yet at a loss- which I can promise you is deadly easy to do) they are going to cost about twice what I hoped to bring them to market for.  Still – They work.  And the relative benefits just keep stacking up so I’ll just have to wait and see what I can do.

Gotta run.  Late for work – again.

And of course the vegetables would need to be organically grown- to do anything else runs so far against the trend as to be a waste of time.

The first bonus was a cut and come again salad greens garden that not only grows well in its hydroponic garden but has produced a better yield than expected.  In fact that advantage continues to grow.

Even though the lettuce has bolted....

The oak leaf lettuce in the shot to my right has got leaves that have extended a long way up the stem.  if this lettuce had been planted in the ground it would be completely inedible, since once it starts to bolt salad greens are incredibly bitter.  This lettuce still tastes terrific.  It’s still tender and not bitter and a true delight.

I’ve concentrated the harvest lately on one half of the garden so I can pull it up and reseed for the second season – which should be good becuase it seems that summer does not really want to come to Toronto this year.

Still many salads left on the left

As you can see, the left hand side of the garden where I backed off a bit for the last three meals has tons of greens left, so while the right hand side re-sprouts, I’ll be dining on the left.

I’ve also been playing with the design for the tomatos and the real question is just how small can the pots be to produce a good yield.   I’ll let you know more about that soon because I’ve got a Brandywine heritage tomato and a beefsteak tomato in what are definitely undersized pots.  They got a later start than I would have liked, but they’re starting to take off now.

Looking over the numbers I’ll be able – I think- to bring different variations of this garden plan to market starting at about $60.00 . Still sorting out the line up and confirming what works.

And even though I’m trying to develop a product -  urban hydro gardens and bring them to market and I’m still fine tuning the prototypes and starting to juggle the numbers.  Sitting ( or standing) around plants that I’m growing is the most soul easing place in the world.  I sincerely believe that anyone who loves to grow plants gets the same feeling.  It can be stretched a little out of shape now and then, when the slugs are eating holes in my pepper leaves and the earwigs are treating my romaine lettuce like a high rise condo.

It makes me wonder if people with other passions get the same sense of peace or if maybe this is just something special that’s given to people who love to ( or is that need to? ) grow things.

I can swear to you that the plants I have in the hydroponic gardens are growing better than my pampered little beauties in their pots of compost- and they are much easier to care for- probably because I don’t have to water them every day and don’t need to worry that they’re going to just about expire if we get a hot day and I’m not around to water them

This is what I was aiming for when I started this project.  High yield, organic and super low maintenance vegetable gardens in a small space.  It’s all coming together now, but there was one thing I had forgotten about – Earwigs!

In my 20’s I did battle with them, only to learn that it isn’t worth the trouble and now I have them again, hiding in the lettuce, dining on my basil and chewing great jeezly holes in my peppers.  Thirty years later and almost nothing has changed – except me.

The next thing to think about is the question “Why?” as in’ Why do you want to grow your own vegetables?”

If you want access to favoured or hard to find treats like oriental eggplants or thai basil or snow peas that don’t have the texture of cardboard,  or heritage tomatoes- thats one possible reason.

Another is that you’d simply like to grow a few vegetables that you and your family like and ýou want to know beyond a shadow of a doubt that they are organic,  chemical free and as fresh as possible.  Another perfectly valid reason.

Another reason is that, even though you don’t have much room you want a vegetable garden that will make a solid contribution to your families consumption by  improving the quality of what you get and at the same time saving some money.  Value is good.

Or just maybe you’ve simply  been bitten by a desire to grow something, because it will make your soul happy.  Welcome.

Every reason is a good one.  Heck I don’t think there can possibly be a bad reason for growing a vegetable garden.  But if you’re going to be growing on a patio, balcony or deck , space will be at a premium.  If you want to be happy with the result, it won’t hurt to give a little thought to what result you’ll be happy with.

Every reason I’ve outlined will take you down a slightly different path when you plan your own garden- and anything is possible.

And everyone is working with the same simple equalizer- sunlight.  If you want to grow vegetables you need sunlight and lots of it and preferably you need sun morning – noon and afternoon.

The amount of sunlight you get is the number one factor you need to take into consideration if you want to grow vegetables in containers and it’s probably the only consideration that you won’t be able to find a work-around for.

I’d say as a rule of thumb your bare minimum to grow vegetables is 5 hours of direct light and I mean direct afternoon sun.  A spot that only gets morning sun simply will not cut it- sorry.  So think of sun from lunch to 5 and remember that’s the minimum.  You’ll get growth and a few things will grow reasonably well- but most of your plants will never hit their maximum potential unless they get the light all day.

This is especially true of tomatoes. They are -without a doubt -the numero uno vegetable choice, which you have to admit is a little ironic since technically, tomatoes are not a vegetable- they’re a fruit. sorry I couldn’t resist.

I shouldn’t have put the aggregated clay at the bottom of the bags, not sure why my brain was dead that day but until the roots reach into it, the clay doesn’t allow the moisture to work it’s way higher up into the bag.  And the roots aren’t likely to reach the bottom when the top and the middle – where they’re living now doesn’t get the nutrient.  I made the same mistake with the pipe gardens, but I used very little aggregate so some of the coir still made contact with the moisture.  This is not to say that any of the plants are doing anything less than thriving- they’re growing like gangbusters!

Even though the hydroponic test plants were 1-2 weeks behind the plants I potted into traditional containers with compost and soil,  they have pretty much surpassed them in size and have started to flower sooner.

The pipe gardens so far are total winners ( a.k.a. nothing has gone wrong yet) I’ve had 3 salads so far from the container greens- very satisfying and once the cukes take off I’d better dig up the pickle recipe again.

I now just need to refine the pipe gardens and figure out the most economical way to produce them- and I need a stand for balconies and patios that don’t have a place to affix them vertically and for people who don’t have the time, tools or the desire or skills to do that kind of job.
