In the GH I am restoring, I put some old paving bricks down to cover
the dirt floor before thinking about the potential weed problem. Is it
safe to use Roundup on the weeds that come up inside the GH, or should
I go to the trouble of removing all the bricks and putting down
weed-blocking cloth? Thanks.

Yes it's safe, although a little scalding water works fine also.

Go through the trouble. Roundup does not prevent weeds from sprouting up. It's
a systemic pesticide which must make contact with the foliage, and in a
greenhouse the drift can vary and cause you to lose plants.

how about some salt?

In a confined space like that, I would only apply Roundup with a brush
rather than spray. I think you might prefer a more permanent, non-chemical
solution.

It is never recommended to use RoundUp if it is not for professional use.
Try to get rid of the weeds manually and indeed, use a nylon cloth, as you
probably will need this anyway. It is a non-chemical solution with more
lasting effects, but the investment is a bit larger.

The best option would be to remove the bricks and any organic soil under
them, replacing it with gravel to bring the grade to the proper level.
This will not only remove the growth media and seed bank for the weeds,
but will minimize fungus gnats, which breed in the organic material,
whether or not there is a weed cloth over it.

Also, if there is really organic material under the paving bricks,
walking on it will eventually compress it to the point where it is
impermeable to water and you will have drainage issues. The gravel will
mitigate that (although you really only have to worry about it in the
walkways).

However, this solution is a lot of work and has a limited lifetime. You
will be occasionally spilling growing mix etc, adding to the organic
component of the subsoil, so eventually the fungus gnats will have a
place to reproduce. You can stretch this out by placing the weed block
cloth on the surface. This will allow you to clean the floor
periodically, minimizing the amount of organic material reaching the
subsoil. I have weed block cloth (the woven polypropylene stuff) that
has been in place for about 10 years now and it's still in good shape
despite having been walked on all that time.

Deal with it, Shill.
Using a herbicide inside a confined space is never recommended. Even
braindead zombies ought to be able to look up application/instructions when
it comes to the ill-advised use of glyphosate. But judging by your spelling
skills, you no doubt did not know that. The stuff has an application but it
is not designed/formulated to be a weed barrier in a hobby greenhouse. Here
is a handy link with picksurs! of application/protection:
http://www.bugwood.org/PAT/16exposuretopesticides.html

Hot, salt water. Or a flame torch. Or a layer of pebbles, aids in passive
solar capture and helps regulate moisture levels. Or even a pre-emergent
such as Corn Gluten Meal on top of a decent quality weed barrier. But not
RoundUp.

Don't bother with a ranty reply, you are not smart enough.

Roundup is definitely recommended for home use but it is important to follow
directions. Most of us possess the intelligence and literacy to do that.

Try to get rid of the weeds manually and indeed, use a nylon cloth,

Or any kind of non-rotting water-permeable weed barrier. But that has
nothing to do with Roundup being unsuitable for non-professionals. It's
simply more appropriate in this application.

Dave, I think it may depend on where you live. It is my understanding that
some countries have banned or restricted its use. It is also possible that
it is banned or restricted in some cities (anyone from Toronto who can tell
us what is its status there?).

A few communities in Canada have outlawed the cosmetic use of herbicides.
That is mainly against the broadcasting of lawn weedkillers, but can include
other chemicals and uses as well (not sure if Roundup is on the list). But
that was not what I was thinking of when I mentioned that Roundup is
"recommended" for use by non-professionals.

Personally I find Killex to be more irritating than Roundup. I use lawn
weedkillers as little as possible (I use a hand spray-bottle, and squirt
directly on the weeds), but will pull weeds by hand if practical, which
unfortunately it sometimes is not.

Can anyone comment on the information at the following link:

This link gives an example of Roundup being declared a restricted use
chemical; (can anyone from this part of the country comment?):
