Tomato grow bag tray

[sandysoil]

Good morning all,

looking for advice on the use of growbag trays, I have bought them for my greenhouse and plan to grow tomatoes, this will be my first year with the green house.

do you:-

1)put the bags in the tray and puncture some holes in the bag, so that when watering you can add more water to the tray and the bag can absorb this through the holes too?

or

2)put the bags in the trays and just use them to keep your green house tidy with no holes being added to the bottom of the bag?

i think the latter has no real benefit but my father in law has advised against option 1 and he only uses option 2.

many thanks for all that reply.

I don't use grow bags so may have misunderstand but if you don't put holes in the grow bag then how will it drain?

Hi sandysoil and welcome to the forum
I put a few holes in the bag, on the side, so that if I should overwater, the water can escape and not stagnate in the bag. If they were on the bottom of the bag, sitting on the tray, it couldn't drain.
Let us know how you get on

Hi Alison and Veggiechicken,

thanks for your responses, correct on the drainage, ill put some holes on the side as you do, just want to make sure they get enough water as I hear tomatoes need LOTS of water.

many thanks for the welcome Veggiechicken.

ill hopefully keep you successfully updated.

To help with watering, use a plastic milk container - 4 or 6 pints. Cut the lower half off it and turn it upside down. Stick the neck of the container in the middle of the growbag so that it stands upright. Fill it with water, rather than watering the plants in the growbag. This way, the water goes to the roots and doesn't splash on the leaves.
Hope that makes sense

A photo from last year with the toms in growbags on the shelf. You can just see the milk containers in each.

thanks for that Veggiechicken, are you putting one milk container per plant or per growbag, or if im putting 3 plants in a growbag, put a milk container in the middle each, so 2 containers.

great idea will give it a try when its time.

I put 2 plants per growbag with the container in the middle. I only use growbags on the shelf in the GH where there's little headroom. All the other toms grow in pots.
