Batch#01 - 11 Feb - Day 63 (CNY Eve)

It's CNY Eve!

And amidst all the preparations, completely forgot to take any data!

Good news is that all seem to be growing well!

So let's log some info on system maintenance.

Algae issue

Some algae started to form around some leca after seeding of new Cos seed batch. Likely due to wet leca. Fortunately issue is not pervasive and as the leca dries off, the algae issue seems to have taper off.

Instead, some white powdery substance seem to form on some of the the leca. Suspect that this is calcium deposit. Likely due to the introduction of calcium nitrate.

A slight rubbing action can easily remove this white powder.

Healthy Roots

According to Benn from Bootle's, signs of healthy roots are the "clean", crisp touch of the roots. If the roots feels slimy to the touch, then it is an indication of problem with the system. So far the roots feels healthy and therefore delaying the need of cleaning and reseting the system. This sample is from a 22 days young Cos lettuce.

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 ...

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...

Kailan and Dwarf Green Curled Kale Experiment

9 July Seeded the first batch of KL and DGCK onto grow sponges and placed them onto a bed of wet leca. Did some research and found that generally, KL and DGCK EC requirements overlap that of WCBC, which is 1,200 - 1,800. The idea here is to try out the diversification of greens from the same pool of water and nutrient in the Yashponic Ebb and Flow system. Thus far, the system has been used to grow White-Crowned Bok Choi (WCBC) and Red Amaranth with pretty good consistent, albeit slow, yield. If these germinates well, it will be used to replace the top and second tier of the current system.
