> You can but you need to water more often, raised bed have a greater evaporation rate than the usual method.

the radishes always were seeded early in the year, i think it's wet enough.

> You also need a good input of composted material.

i have a compost going where all the uncooked vegetable peelings etc. go, i think i'll mix it with some normal humus from the garden and try that.

> I don't recommend use wood pallet for this usage, they'll contaminate the soil. it's better to use tree trunks.

good point! they are probably treated with something. well, then i'll just use the frames as random boxes for stuff in the shed :D tree trunks are a nice idea, i just have to get them :)

i'm not really sure if you can prevent the worms. maybe it was too wet. i think i've read somewhere that you also can plant things (i'm not sure about which plant right now) alongside the other vegetables to prevent the worms. another thing might be putting a kind of fleece ontop the plants to prevent flies laying their eggs.
