Started 2nd attempt of hydroponics on 24 Sept 2015

24 Sept 2015 – Germinating seeds with “Diamond Water”

27/28 Sept 2015, Looks good.

30th Sep 2015 – Looks kinda leggy. Could be lack of sunlight during this period of Haze.

3 Oct 2015 – transplant over to netpot. Plant is not as big as I like, did this hoping that plant can get correct nutrient and lights.
 

4 Oct 2015 – This is how it look like after one day. Look at the size of 3rd leaves compare to the day before. I’ve adjusted growth light to provide lights from 07:00 to 13:00, 6 hours of lights.

Set this growth area with space for 18 netpots. Managed to get 12 reasonable sprout. Lets see how this go. I’ve got my growth light hanging where I can adjust its distance from the plant.

Getting the nutrient right is tricky, adding 50ml of A/B solution to 10 littles of “Diamond water”. I got a EC about 2.3 and pH 3.3

It’s too acidic. I’ve added “Backing Soda” to up the pH to around 6.1. Nutrient concentration wise, I added 4 more little of “Diamond water”. Solution settled down at EC of 1.965 and pH 6.55.

Learning from this, we should adjust EC before pH.

5th Oct – growing, didn’t expect the shoots to sprout out in the 2nd photo. Which one should I trim off.

6th Oct – grown a bit, not much

7th Oct – growing

17 Oct – Plant on 1st row is growing pretty well, not so for those on 2nd row. 1st row has exposure to direct sunlight. I’ve extended the growth light to 8 hours – 7am – 3pm, lets observe.

18-19 Oct – it can grow pretty fast. Look at the centre leave. This is how much it grow in one day.
