Stolen plant, I'm gonna miss you

Ok so this week i didn't have any time at all but I managed to adjust the LST and set the automatic watering system. It's a little thing I bought on Amazon for about 25€. It uses 4 AAA batteries. I set 1.50 minutes of watering every 24 hours. It should keep them safe and moist. I also covered them with the transparent umbrella since we are expecting summer storms. I'll be on vacation for about a month, but I'll be back two times and for several days. I also have a friend who can come and check on them. My only regret is that I won't be able to further adjust the LST and give them nutrients... Before I go I'm going to water them with a good rich manure tea and plant some bushes around them. Probably some easy peasy Basil or cheap stuff like that.
