What do you guys think,will they be ready to harve...

Plants are looking very healthy!! as for a drip system to keep it going while youre gone - get a big resevoir with an air stone to keep the solution oxidized, place it at a high place above the pots and connect a timed valve (usually found in garden stores/greenhouses/online) that switches according to your watering needs! from the valve spread a drip system across your plants. With big enough resevoir you can keep it going for more than two weeks without maintaining it! Hope this helps! Good luck and happy growing :)
