Hey guys, so nice to see seedlings doing their thing.
Looked up Lisbon on the map, 38N Latitude. That compares nicely with NoCal or Oregon climate conditions. Hot and dry unless it raining cats and dogs.
Getting them through the first couple nodes of growth can be a challenge, every hungry bug on the plants wants a piece of them. Grass hoppers are my bane.
For the most part, you don't have to be concerned by rain or stormy conditions. Your first pic spread shows them on flat ground. I would be a little concerned about runoff rainwater. If you are clear of the actual drainage zone, you will be good.
Good luck, keep an eye on your progress.
