Batch#01 - 07 Jan - Day 29

Just a Normal Day of Growing


And yes, we are heading into Day 28, the day planned for harvest. Lettuces are still as thirsty as ever, needing on average a 2L top-up daily.

COS/ROMAINE:



GRAND RAPID:

Looks like GR is not ideal for repeat harvest due to the fast-growing stem. It's growing rather fast so much so that as the leaves at the top grow bigger, there is no longer denying the effect of gravity. The bigger and heavier ones droop down and a few, actually fracture. Although some may still stand upright but sooner or later the weight will cause them to droop. Just wondering if there is some micro-nutrient that is insufficient. Calcium perhaps? Something to look into.

A little research later, it seems that calcium deficiency can lead to tip burns in lettuce leaves! And found a little interesting titbit - calcium can be picked up via the roots or leaves end! So spray bottle of calcium nutrient apparently works too! (though not planning to head that way for the moment)

Article on calcium deficiency and its symptoms on plant.

Tip on how to DIY calcium nutrient from egg shells! 



RED OAK:




BUTTERHEAD:



DATA:

EC1062

- good range

pH6.46

- added 10 drops

WT28

Water level: at min level

- added 2L of water, but just 5ml of ABC, moderated with 6drops of down

- cut down the vol of ABC since current EC is in good range.

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.
