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.

Batch 1 - 7 Mar - System Shutdown after 88 Days

Batch 1 Shutdown (88 days old) The system before Shutdown. Reason? The persistent "fungal" problem, shown below. No matter how often I trim off the outer leaves, the yellowing continues to propagate. As for the Lollas, browning along the leave stems are accelerating. Red Oaks looks OK though. So it's likely the water is not healthy in some ways, though EC shows 1040. Didn't manage to measure pH. 8Mar update: A fellow UF member shared this site on leafy plant issues. Dengarden . Looks like Yellows. About Yellows Yellows is a fungal disease caused by Fusarium oxysporum con-glutinans, and triggers formation of large, dull yellowish green patches on the leaves of vegetables. The harmful microorganism survives in warm conditions, which means that you can prevent it by keeping your garden at lower temperatures. The disease can be spread by farm tools, so ensure you clean and disinfect your tools before using them in your ga...

YESH! My Yashponics Kit has arrived

The Eagle has Landed! And so here it is. Not exactly an eagle, but the Yashponic 4-tier black kit. After a short 4 days wait after placing the order for pre-existing stock, the box arrived yesterday, late evening. Time to be Bob the Builder Decided to start on the hardware set up today, since I am unsure how long it will take me. As shared in the videos put up by helpful Yashponics owners, it takes around 2.5 hours. The assembly videos are helpful. They gave me a good idea of how to start and the overall concept of the built. The whole process made all that easier, thanks to the numbered parts. And yes the whole kit is up and ready. Easy to set up? My Verdict... With the videos provided by Yash, the numbered parts, it's totally a breeze to get the whole kit up. Took my time to unbox the parts, lay them out (in other words, you need some space for all these), and put them together. Only boo-boo along the way is that I forgot to rinse all the parts as ...

18 Jan Bok Choi Harvest #4

And yes... after just 15 days, the BC are ready harvest again. Round 4! Sturdy green leaves. Rrally happy with the deep green look and feel of the BC. Harvested 2 large bowls from 12 plants from both tiers. There is very little wastage, just a small handful of yellowing leaves. And yes, into the wok they go for a big plate of BC stir fry with fish cakes, the family favourite. The before and after harvest look. And after... The bottom tier is showing good growth of White Crown Bok Choi. These are the slimmer and greener stem cousin of the BC. Growth is pretty fast too. Seeded on 31 Dec. EC kept to 1200. Looking forward a new batch of green for the LNY!
