Finally, I have seen various different manufactured materials at Home Depot that may suit your need as a tray lid. For example, 6" wide by 40" long by 3/4" thick boards of PVC for making weather proof outdoor decks. Several could be placed side by side to make some sort of light-proof lid that would accommodate the 9 plant sites. If you are placing the plants directly into the tray, here is another option: get a roll of Panda plastic (black on one side, white on the other side, pretty thick stuff) and cut a 4'x 4' piece to go over the top of the tray. Pull it snug and tape it into place well. Then simply cut a hole or an X in the plastic film in each spot you wish to place one of your plants. You may have to replace it each time you flower a new crop, but it is cheap, and it will keep the light off of your nutrient solution!
Hi everyone, Jason from Jason's Indoor Guide here. When I got started
with hydroponic gardening more than 22 years ago, my first garden used
rockwool cubes and B.C. Nutrients....and I remember thinking to myself
yeah, sure, there may be a lot of advantages to gardening with
hydroponics, for example there are very few pest problems, therefore
very little pest control, no weeding, no plowing or tilling the soil, no
soil testing or having to add things into the garden soil, no watering
the garden....but for someone who just wants to grow their own
vegetables and have more control over their food supply and the quality
of the food that they eat, the cost of constantly having to buy grow
media and hydroponic nutrients makes this an expensive hobby for most
people.
I suppose when you take into consideration how much money you save NOT
having to buy food at the grocery store, it is surely cheaper to grow
your own food hydroponically even with the cost of high quality
nutrients. Nevertheless, I didn't have a whole lot of money to work with
and I needed to make my efforts as affordable and effective as
possible....and in the last 20 years I HAVE learned a thing or two!
As you browse through Jason's Indoor Guide, you will notice all of the
systems that I use personally are homemade systems. As I got 3 or 4
years of experience under my belt, I quickly adopted a preference to
standing water systems and systems that use expanded clay pellets or
lava rock, because the media is re-usable and it eliminates a huge
operating expense. So once a hydroponic system is built, garden
maintenance is minimal- check and adjust the nutrient solution daily,
and to change it completely every 2 weeks....and the biggest operating
cost is the hydroponic nutrients. (and the electric bill, lol).
And, regarding the cost of the nutrients....I experimented for about 3
years with making different compost teas and nutrient teas, but there is
still a lot of expense $$$ associated with making high quality nutrient
teas....like kelp meal, liquid seaweed, rock dust, bat guano,
un-sulfured molasses, worm castings. You can eliminate a lot of this
expense by becoming an expert at making high-quality colloidal humus
compost, and use your properly made compost as the basis of your
hydroponic nutrient solution.
Unfortunately, I have been gardening for over 20 years and I have only
just recently mastered this difficult skill....and even then, only
because I happened to find a very easy to follow, high quality technique
and decided to follow the instructions to the letter. I produced more
high quality compost in just one week than I was able to use in a whole
year! I highly recommend it. It is one of the top 3 things you can do to
increase the productivity of your food production efforts, while at the
same time decreasing the amount of effort required to grow all of your
own food, and decreasing the total cost of operating your food
production system.
And when I say decrease operating costs, I mean decrease them to almost
ZERO, especially if you are producing your own nutrients.
One final solution to eliminate the cost of your hydroponic nutrients: Imagine a hydroponic system that does not require you to buy any nutrients, does not require you to make your own compost, and does not require you to brew your own nutrient tea. Seriously! No cost and no effort as far as providing nutrients to your plants is concerned. Plus, at the end of the gardening cycle, you harvest all of your garden vegetables, PLUS YOU HARVEST FISH from the system!
This solution is aquaponics. If you are serious about producing all of your own food and being self-sufficient, this is the ultimate solution for reducing expenses (as much as possible), reducing the total amount of work required, and maximizing the productivity of your gardening efforts. I have been gardening for over 20 years, and it is the perfect food production solution in my opinion.
Besides mastering how to make high quality compost, learning aquaponics is one of the top 3 things you can do to increase your garden productivity, reduce your total costs, and reduce your total work. The product that I learned from is called Aquaponics4you. With all of my hydroponic gardening experience, the first time I came across the Aquaponics4you product I knew immediately that it was something very special! Place an aquaponics system outdoors and use the sun instead of grow lights, and you have reduced every garden expense to nearly ZERO!
This is where my advice ends for people growing in water. But some of
you out there are in love with soil gardening and organic gardening, and
rightly so! It's a pro-human activity. It is pro-conservation. It is
pro-life. It nurtures and promotes life at all levels, from the
micro-organisms to beneficial insects, to healthy humans. It's natural.
it's spiritual. Gardening is written deeply into our DNA, like how you
feel watching a bonfire or sitting by the ocean or next to a river.
My friend John at Food4Wealth has more than 20 years experience organic
gardening, so he reminds me a lot of myself. He knows organic gardening
like I know hydroponic gardening, and over the years he has learned just
about every trick there is to organic gardening. He knows what makes
the plants grow, and he knows how to do it with as little effort as
humanly possible. His garden never needs digging, naturally repels
pests, has no weeds, always produces more than his family is able to
eat, produces vegetables everyday all year round, and....only requires 8
HOURS of light, easy effort PER YEAR!
Years and years of experience and results can't be argued with....the Food4Wealth gardening strategy is one of the top 3 things you can do to increase your productivity, reduce your total costs, and reduce your total work....specifically for organic gardeners who love soil gardening. THIS is the most efficient and productive way to do organic gardening, period! And combined with the ability to make a years' worth of colloidal humus compost in just one week (see World's Best Compost), this overall organic soil gardening strategy is just unstoppable- foolproof, low cost, and low effort!
