Square semi-hydro pots? Source?
 

Do people use square pots for semi-hydro? Where’s can I find some? Thanks.

Google ("square plastic container") can be your friend.

Here's one example.

Thank you. Google has been my very good friend for about 20 years. I was hoping to get particular tried and true pot recommendations from those who have been square pots for S/H.

I have almost all my SH in square translucent plastic tupperware type containers. Walmart, 4 for $7. Come with lids, I pitch the lids. They stack one inside the other so I get several sizes with each purchase. Roughly size is gallon, half gallon, quart, and pint. Sometimes Dollar store has them.

I don't think you need "tried and true" necessarily. Anything will work. It's just preference. I use these at present because I did a ton of repotting, they were cheap, and there's a Walmart nearby. They're like the real deal soft rubbermaid plastic, not the hard brittle stuff. Last for a long time. When I want to display something that's actually blooming, I just stick it into a decorative pot. Used to use a lot of glass. Decided it was silly, for me, because I have more orchids than common sense at times. Much easier with plastic to repot than glass is. Glass is much prettier if you just have a few, but when you get into higher numbers, why bother? Just my opinion.

Any particular reason you want square? Just curious.

Edited to add: By the way, Ray is inventor of Semi-Hydro. If it can be grown in SH, or even if it can't, Ray's likely already tried it. His short advice was on point... you want square and plastic? Here ya go... square and plastic. After that, it's just preference.

Thanks! I prefer square just because I’ve found them to be a bit less tip-prone and top-heavy than round plastic pots. I have a fairly cramped growing space in my office, and have already experienced a few “oops” with a couple round pots. But it’s not a major consideration.

Gotcha. Check out Walmart or somewhere similar, or Amazon. I like the ones I'm getting because of the different sizes and I like to keep a bunch "extra" on hand. You may find something you like better if you want more all one size or a couple of different sizes.

When I was having S/H pots produced for me, the square containers tended to be thin-walled PET, making them much more prone to breakage during drilling than either PP or HDPE.

Now that I'm the "consumer" side of S/H, I too tend to cruise the aisles of dollar stores, Walmart and the like, grabbing whatever will work for my current need.

Thanks, Ray!

My two cents of advice regarding DIY-ing semi hydro pots: don't drill them. It's not worth the hassle. The plastic will most likely snap and break and you can harm yourself.

Instead, use a welder, the ones with a thin tip that heats up that and are use for electronics (not sure of the english name for them). Melt through any holes you wish to do in the pot. It's a lot easier.

Thanks for that tip. I was thinking about poking the holes with a soldering iron (that’s what we call them). Good to know that wasn’t a crackpot (no pun intended) idea.
