Batch 2 - Day 17

Batch 2 - Day 17

All the lettuces are growing fast and well. Can't help but admire the growth rate everyday, especially the morning after, where the growth can be quite significant.

So it seems like the cleaning of the system seem to have gotten the balance back. Complemented by the pool noodle, and USB fans and not forgetting the method of seeding. Which I suspect is a key contribution since I don't have to thin out excess sprouts, which may caused broken roots within the leca, thereby messing up the nutrient solution due to the decay and inevitable introduction of bacteria and fungus.

EC=1120, pH=6.75

Another observation is that with the pool noodle, there seem to be less evaporation. Hence water level does not seem to drop as rapidly compared to the past. The wet leca balls and capillary actions that leads to the perennial wet surfaces would have contributed to higher water loss due to evaporation.

21/11 Bok Choi update

21 Nov, marks the 22 days after transfer of BC sprouts to the system. Growing well with EC ars 1400. Simple to maintain and seems to be pest free. Spacing them out also allows the lower leaves to get enough light to grow well with little yellowing and hence waste. It's a no wonder that many hydroponics producers are into bok chois. Easy to grow and taste pretty sweet and crunchy. My helper mentioned an interesting observation when I said that the BC are ready for harvest in 2 days. From someone who cooks regularly and with longer experience handling greens, she observed that sometimes the BC she purchased from the shop has a not-so-good smell to them. She suspect that this could be due to the freshness of the supply. And it's hard to tell from the packaging cause the green "look fresh" This suggested the need/importance of having microfarm model, similar to that of energy microgrid, to ensure fresh produce is accessible to everyone.  How this w...

Batch 2 - Transplanting L211

Transplanted L21 for experience Added 20ml of A B into T2 and 4. Initial EC shows 340. Switched on air pump and increased the flow rate. Will check EC tmrw.  Decided to learn by experience how to transplant the little sprouts into the pool noodle. Not easy admittedly and also there is this lack of confidence that the roots are long enough to reach the water level sufficiently. Pressed the noodle until its almost flushed to the base in order to let the roots reach the water surface.  Seems like 8 days after seeding will produce roots averaging 3-4cm long.   Let's see what happens tomorrow. Recover well from the trauma of being moved lil ones.

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.
