Batch#01 - 11 Jan - Day 33 - Lollas are coming!

Lolla Lettuces are Sprouting!

Seems like the Lolla seeds did not drown after all. Or rather this little one managed to survive the flooding after all!

Instead of going through the usual series of pictures to compare the growth and form of the lettuces over the course of 30+ days, it's time to just focus on learning points. For today, it seems that the tip burn on the Cos is getting worse. In fact, I suspect that for a few leaves, it's not just only tip burn, but some nitrate or calcium deficiencies.

Asked for advise on FB Hydroponics group, seems to confirm that indeed these signs are likely caused by:

lack of regular air flow to promote evapotranspiration (which leads to better nutrient uptake); or
lack of nutrients such as calcium and nitrate.

Since I have not had the time to source for and install a portable fan, decided to order some 200g calcium nitrate powder from Shopee.

Data

EC960

- a little below the average.

pH6.25

WT28

Water level: at max level.

- Since water level is near to max, decided to just top up 1L of water, with 5ml of ABC and the all-in-one Grow solution, moderated by 10 drops of down.

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.

Batch#01 - 21 Jan - Day 43 (GR microgreens!)

It's all about the GR microgreens today! And that is just 2 days after seeding. The kitchen towel method seems to be working till now. Let's see what happens in 8 days. For the time being, will keep the cup to cover the mini sprouts. Now the lollas. A close-up of the tip burn like of the cotyledons. Interesting to see that the lolla young leaves are relatively tender and thin compared to Cos. DATA EC1532 pH5.83 WT29 Water level: at mid level.

Batch#01 - 31 Dec - Day 22

HARVEST TIME! GR for New Year's eve dinner! Finally harvested 134.9g of Grand Rapids for dinner! The before, harvest and after look! Leaving some leaves for brekkie tomorrow!
