30/10 Bok Choi experiment with sponge

Trying our seeding and germination in sponge. The germination of BC is pretty fast in a simple greenhouse set up.

Did not wait for true leaves but the emergence of roots from the sides and bottom of the sponges prompted me to consider an early transfer to the system.

Tried out 2 methods.

Pool noodle Cut Out

Cut the pool noodle to accommodate the square sponges. Concept here is not to exert to much pressure on the sprouts and to have the elasticity to allow for growth.

Also at this early stage placed the sponge deeper into the pool noodle to allow the bottom to touch the water in the troughs.

In leca

The concept here is not to waste the leca. The thinking is that if the sponges are placed deep enough in the leca, they should be able to absorb the water from the trough.

Comparing both methods after just 2 days, don't seem to show much difference. The only observation is the the sponges in leca is dry on the surface, but not the sponges in pool noodle.

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.
