Batch#01 - 20 Dec - Day 11

The usual Sunday morning except...

There are 3 new "additions" to the Oon hydroponics family. Stevia, Mint, and Thai Basil, using the Kratky method. Stevia and mint are from Citiponics, which has shown signs of rooting from stems. Thai basil is from seeds from Woodsquare rooftop, germinated, and are in full bloom along the corridor.

The current setup... with the 3 new members placed on the floor, to take advantage of the grow light. Mint supposedly needs just a medium amount of light. So it should be fine. Will have to monitor the stevia and basil.

The usual photos from Tier 1 to 4.

Trying out a new perspective today.

Today's reading:

EC1040

- Good. A slight increase due to the addition of 10ml of A, B and C into 2L of water ytd, to top up the nutrient level.

pH6.7

- Despite the use pH effort on the 2L of water (added 1 drop, that resulted in pH 4.4), the mixing overnight has caused the pH to go up. Now, with greater confidence, 2 drops of pH down were added each to T2 and T4.

- Although quite a number of growers seem not to care too much about pH level, leaving it at 7+, for this Batch I will try to adjust it to the desired range of 5.5 to 6.5. The thinking right now is that with the correct pH range, the nutrient and mineral take-up rate would be in a relatively more optimum state, contributing to better tasting lettuce.

WT28

- Noticed that the water temperature is about 1C above the ambient. Could be due to the heat generated by the grow lights, stored in the reservoir body and being released to the nutrient slowly over the course of the day/night.

Added 2 more drops at 6.30pm after pH shows 6.3.

Also added 5ml of ABC. T4 shows EC940.

Batch 2 - Transplant Cycle 2

Transplant Cycle 2 Transplanted an assortment of GL and L211 mix that is about 7 days old. These came from seeding that was done on 9 May. Leftover sprouts. Tried to grow Chinese Kale via Kratky using the wicking method planter pots and two 20W E27 grow lights. A close up of the CK sprouts.

Boxing Day Wondergreens Greens are growing great and with the state of the GR, I am thinking of thinning them out tomorrow. Get the younger ones, one each per pot for brekkie salad. Tier 1: CR Leaves are deep green in colour, a slight contrast to the usual romaine that we have for salad from the markets. All looking healthy though. Another observation, the leaves are open. Tier 2: GR Observed some minor tip burns, but not too many to be of concern for aesthetics. Tier 3: RO The leaves are losing the reddishness. The pace of growth is slower than both the CR and GR. To take note of this when planning for sustainable supplies. Internet sources suggest that maturity is between 45 to 60 days. Tier 4: BH Growing well too. No burn tips. Judging from plant size (diameter and height), growth rate seems to be just a little slower compared to GR and CR. Data EC1200 - Nice! After adding the 10ml of ABC yesterday together with the 2L of water. Overnight mixing has resulted in a higher ...

HARVEST TIME! GR for New Year's eve dinner! Finally harvested 134.9g of Grand Rapids for dinner! The before, harvest and after look! Leaving some leaves for brekkie tomorrow! From the top to bottom again: Cos/Romaine: The Grand Rapids or what's left over! Red Oak: Butterhead: Data: (before harvest) EC1146 pH6.93 - once again, the pH crept up again, despite adding 6 drops of down yesterday. Time to adjust it downwards once again. - added 10 drops of pH down. WT29 Water Level: at MIN level again. - Topped up with another 2L with 10mL of ABC. Adjusted with 6 drops of Down.
