BH is not germinating as well compared to the rest. 11/12 (92%) from BLH pelleted seeds. These are the ones on the right side. Only 4 sprouts from the Yash seeds that was sprinkled over the 6 pots on the left.
Nonetheless, a good experience thus far. Pelleted BH seems to have far higher germination %.
EC1040
- interesting to note the increase in EC. Could be due to evaporation of water. Water level has dropped to almost the min level.
pH7.3
- is consistent.
Action
Top up with 1L of nutrient mix, with the following EC400 and pH6.8 from the balance from Day 0. Find that the water level did not change by much.
Added another 1L. Added 2 drops of pH down and brought the pH from 7.8 to 3.5. Did not add any ABC since initial EC1040.
Added again 1L of untreated water. All in all, a total of 3L of water nutrient mix.
This time the water level went up. From estimation, 1L of water = 3mm of water level rise.
Final EC840
- which I thought is OK since it is still germination stage.
Final pH5.8
- measured immediately in tier 3 which I added the mix, which is OK. I suspect the pH will balance given some time.
Other actions:
Added aeration in Tier 3. (from spare air pump from earlier DW kit) Tier 3 cause it's the mid point.
Added DIY corner filler. Made up of two components:
1) hair band, and
2) Black corrugated board cut out as shown.
Since it is challenging to cut out an exact circle, I cut out a hexagon shape core. The space between pipe and cut-out is filled out by the hair band.
That should:
1) reduce evaporation,
2) prevent insect infiltration, &
3) block as much light from entering the Reservoir, to slow down algae infestation.
