OOOps. I let the team know. Thanks!
UDPATE: Should be fixed up.
I imagine a 5 x 5 grid of these would make a nice setup … maybe even work out a drip irrigation system to make their claims of soil drainage and more efficient water use applicable.
But, that would cost almost $2,100 for what amounts to 100 pieces of thin-walled extruded metal … and that will buy so many years of fresh organic produce I don’t need to take the time or cost to plant, water, feed harvest or clean …
Home Depot sells weathershield-treated 8’ x 8" x 1" for $7.57, so four boards per cube (stacked to 4’ x 16") x 25 would be $757 …
I only use untreated cedar for growing food. Treated wood is fine for flowers though.
I built 4ft x 6ft x 12in deep cedar beds this year for less than $20 each. Took about 30 minutes to assemble them too.
Is there some type of bottom to it that it can go on decks? It just looks like 4 walls.
I am curious about the same - only thing I could possibly think of using would be some thick plastic. Regardless … even after one season it “would leave a mark” if you decided to ever take it apart and move it
I was under the impression that the harmful chemicals (arsenic etc) were taken out of treated wood - is this not true or can treated wood still not be used for vegetable growing please?
Good question. Here’s a few more. How much arsenic is really in treated wood? How much could feasibly leach into the ground? How much from the ground could feasibly get into your food?
I ask because many foods naturally have low levels of arsenic in them.
I’m not an expert and am def coming from place of ignorance, but I find it hard to believe that enough arsenic could go from the wood, to the soil, to plant to pose any real danger.
Then again, there may be more arsenic than I am envisioning or other more harmful chemicals.
Any chemists, botanists or agri experts out there?
I know that arsenic is no longer used in pressure-treated wood, but was curious about the Home Depot brand mentioned above. Turns out the old CCA (arsenic-containing) variety was safe enough, could be made more safe by taking steps to minimize cracking and exposing the surface to weather for a while etc.; the newer stuff is even more benign.

EDIT Looks like everyone else beat me to the punch.
You’re safe to use treated wood for vegetables. Source = Fine Gardening
I use treated wood in my garden bed and am happy. It was very cost effective. I have a 4’x8’x16" raised bed and it cost me under $60 to build- 6 treated 2x8s, 2 treated 2x4s and a box of exterior screws. Don’t like the look? a quart of exterior stain for $12 will go a long way.
Picture 1, 2
TL;DNR Treated wood has inorganic arsenic so you probably shouldn’t eat it. But it’s fine for gardening.
You shouldn’t put this or something like it on a deck because of the added weight. 4x4x1’ of dirt (at 75# per) would be 1200 lbs. That’s a lot of weight to have sitting in one place, for an extended period of time. While a correctly constructed deck should be able to support that kind of weight, most decks aren’t. That and you’d end up with a discolored section due to the spot being covered. You’d also have to put a liner of some sort inside of it to keep the soil inside. Trouble is that will also cause issues with condensation (water being trapped) and that will degrade the deck and metal sides.
So don’t put one of these on a deck.
As for arsenic or other factors, how many folks here are even bothering to test the soil that’s already present?
Using your math, a 2 cu ft bag of potting mix/soil from Home Depot or Lowes would weigh 150 lbs. Really?
You’re forgetting that a bag of gardening soil or potting mix from Home Depot is completely dry and not weighed down with water.
1 cubic foot of wet soil weighs at least 75lbs, but a lot of that depends on the type of soil, temperature, etc. The gardening community likes to say that a cubic foot of typical soil at average moisture will weigh around 100lbs.
So yes, a 2 cu ft bag of gardening soil from Home Depot weighs at least 150lbs when it is soaking wet.
No real long term studies have been done on the new version of treated wood. If you look around online you will see plenty of articles about the arsenic no longer being an issue but many people are concerned about copper leeching into the soil and therefore the plants.
I couldn’t afford cedar in my area (Northeast US) so I just asked around at the community garden. I found out many people were using untreated douglas fir which is very common around here. Even with direct ground and soil contact most have already gotten 5-8 years out of it.
For the piece of mind, I went with 2’x 12" for my wife’s 12’ x 5’ plot and the lumber only cost me $50.
Anyone else notice the price went from 82.99 to 79.99?
How on earth do 8 pieces of tiny metal cost $80 and who in their right mind buys this?!? Seriously, why would you buy this vs buying the materials for 1/10th the cost?
Well, that explains the back pain.
