Narrative: Sunflower and pea sprouts are looking healthy still. The tomatoes looked like they needed more water again so I gave them about 3 gallons total. I have determined it is from underwater because they look better a few hours after watering. When tomato plants start fruiting they generally need less water but they are in pots that are too small and will need to be transported to 4 – 5 gallon containers. I checked one of the carrots today that was peeking out of the soil. It measured ~ 6 inches and weighed 14g. It was a beautiful purple carrot! In the next few weeks there should be plenty of carrots ready for harvest.
Harvest: 14 g Carrot.
