Change to crops: All the crops in the direct path of the heater are
staring to have crispy, dry leaves despite the daily watering.


1st sprouts: N/A

Harvest: At 4:40 P.M., 18 grams white onions of was harvested.

Other: I was able to fix the temperature of the thermostat within the
greenhouse. The temperature before was at 16 °C and I placed it to 21
°C. Additionally, I planted two pots of snow peas, and one pot of
white onions. The snow peas are placed on plot A, column E, row 7; as
the white onions are on plot B, column F2, third shelf.

The photos requested by Director Rupert are attached below.

Suggestions: Since the thermostat was changed to 21 °C, the floor
temperature has increased to desired ranges (between 10 °C - 15 °C).
However, because of the angle the vents are for the heater, the heat
is directly hitting the hanging plants. Prior to this, some of the
hanging plants, e.g. cucumber, lettuce, and snow peas, had been
burning a bit on the tips of the leaves. By increasing the heat, the
hanging plants are now burning more and the soil is drying out faster.
I was wondering if it was possible to rearrange some of the plants and
place them in other areas of the greenhouse. For instance, since snow
peas prefer cooler to warm temperatures, all the hanging snow peas can
be connected and placed in the back of the GreenHab by the herb bed.
Also, the lettuce can also be placed at the back of the GreenHab and
connected with the other lettuce pots. The Narcissis plants can be
placed on the top of the plant stand in plot B and the spinach tray
can be underneath the plant bed next to the GreenHab doors. I can put
all the watering cans on the bottom rack where the pots and plant food
are to keep things organized, and the metal trellis can be placed in
the back right corner of the GreenHab where the icicle radish’s are.
Finally, I would move the bags of soil to the other side of the desk
so that it will be placed by the rack.
