No, don't be rediculas. You can't ship a live plant, through a company, with a battery operated floro light in there. First off, shipping companies don't treat your package like a new born child. Even if you put a fragile sticker on there, they'll toss it around like a cheap hooker. The lights will break, the plants will get crushed, and what about heat buildup in a crammed, stuffed, cardboard box? You're going to have 2 humid plants, that will generate heat and moisture, with a battery and light? ZAP!! I once received a pack of 40 seeds from a friend that a had a big fragile sticker on it. The package had a size 12 boot print on it. Luckily it made it okay thanks to his good shipping method.

It will be very hard to keep a battery, lights, and 2 live plants, concealed, without getting busted. You get busted, you're fucked.

They are only 4 weeks old you say? Their is a good chance they won't even smell. A lot of strains have a very low plant odor during flowering. Yours is only what, 4 weeks in veg, or 4 weeks from seed? Either way, you can safely conceal 2 plants yourself in a well packed cardboard box, if it's just overnight, without any smell at all. You with your folks still, is that why all the worry? No biggy if you are, but I suggest moving them yourself or forgetting it all. You should have got these clones or whatever after you moved. Good luck!
