Day 3: Dwarf Tomato 'Vilma'

Roots have begun to grow out of one of the seed already. It's the one in the middle. Germination time - 3 days. This saucer is located by a bright windowsill with the warm outside air constantly blowing in.

Day 0: Hawaiian Red Currant Tomato

My dad made me a happy guy by dumping 3 empty CNY cookie containers on my table. Therefore, I decided to go ahead and open up my packet of Hawaiian Red Currant seeds and germinate 2 seeds. Will pick the stronger of the two seeds to plant.

Congrats. I am sure all your seedlings will sprout, and you will not bear to cull any, lol. Time to look for more containers.

Day 3: 'Hawaiian Red Currant' Tomato

One seed has already germinated yesterday and is happily rooting today.

Day 6: Dwarf Tomato 'Vilma'

5/7 have germinated. Seed leaves popped up magically. They were totally hidden in the seed just yesterday.

Transplant complete. Hopefully the tomato grows longer roots soon so that I'll be able to lower the water level. Maybe I should just stack more leca on top.

Nice sprouts! I usually place my wool and seedling in the middle of the net pot, and level the clay balls till the middle mark. Only when the seedling grew longer, I will top up with more clay balls, covering the lower stem. This will help the seedling grow roots from it's lower stem too. Placing a seedling too high up in he net pot will somehow be unstable, because as it grow, the lower stem is not as supported.

These are my tomato sprouts. It is placed in the middle of the pot. I will top up with clay balls once it has grown longer.

Looks like another successful tomato planting.

Day 15: Dwarf Tomato 'Vilma'

http://i8.photobucket.com/albums/a29/chypmunk/Hydroponics/631B085B-58A4-4B85-BD4D-5562BED7A7F8.jpg
Final germination rate is 5/7, right before the water ran out. Thank you Nature and unforeseen circumstances for curbing my overenthusiastic seed sowing! Hoho now I have space to grow other stuff.

True seed leaves have grown. Stems are very thick! Plants are very responsive to light direction. They were tilting to the right side just 40min ago.

Final germination rate is 1/2.

True seed leaves have grown too. Stem thinner than 'Vilma'

Off-topic, but this tub of CNY goodies is currently sitting on my office desk and is in danger of being completely devoured by me!! :drool:/>/>/> Even the container will not be let off that easily!

Nice! My solution pH is fluctuating every morning. Can't wait to see your Hawaiian currant tomatoes grow bigger!

Oh yah I read your post. I'm keeping a lookout on the experiences of those who bought it first before considering

Soooo.... while waiting for office emails to arrive, my hands became itchy and I decided to sow more seeds for hydroponics

Day 0: Pai Tsai 'Show Jean'

http://i8.photobucket.com/albums/a29/chypmunk/Hydroponics/6290ECF8-87ED-41BC-82BD-B032D29B2FCE.jpg

9 seeds. Photo taken before adding water. I'm testing to see how the germination rate is after having been kept in a ziplock in the fridge for 27 days. Also wanna use these to compare with my soil grown counterparts which I've been feeding with fresh fish blood, rice-wash water, and a little home-made compost.

I intend to stuff them all into a single 4.5-inch net pot and grow :hysterical:/>

Day 0: Okra 'Greennie'

2 seeds. Photo also taken before adding water. From Known-You Seed. Will choose the healthier of the two to grow.

Why is the reading fluctuating every morning? Is the PH pen giving a good reading?

Hi Grace! Initially I also thought the pH pen may not be giving good readings too. I counter check with the solution in the chilli plants and also the mineral water (pH 7.2). The solution for the chilli plant always give a reading between 5.5 to 5.8. For the mineral water, 7.0 to 7.2.

Haiz.. I think I will remove all the leca balls, wash everything and set up a fresh new one.

so good! Can do indoor gardening at office.....

Haha I'm in charge of the back office where there's a window there, so I'm hoarding that space!

Hmm. How about you try taking fresh leca, soak it in water for 5-10min, then use the pH pen to test that water to see if the leca is the culprit?

After trying out Known-You Seed and TheSeedsMaster, I'm never going back to Horti again. Maybe it's just me, but I have terrible luck germinating Horti seeds.

Day 1: Pai Tsai 'Show Jean'

http://i8.photobucket.com/albums/a29/chypmunk/Hydroponics/817C9112-972C-4546-837F-5C4E0591E970.jpg
100% germination rate for the nine seeds even after storing in the fridge (in a ziplock) for 27 days!!

Day 1: Okra Greennie

http://i8.photobucket.com/albums/a29/chypmunk/Hydroponics/90B1A895-CA32-4A67-925C-788B1FB0452B.jpg
One of the seeds has germinated as well. That's very fast!

If I hover over my plants any further, I'll probably transform into a helicopter.

Less than 48h and both have germinated and are growing out a thick root each! Keeping track of germination so that I'll be able to plan accordingly in the future.


http://i8.photobucket.com/albums/a29/chypmunk/02AF11BE-98FC-48BE-9623-855AB9525C45.jpg
Off-topic, but this is my Pai Tsai 'Show Jean' grown in soil, after 28 days. Decided to harvest the leaves before more of them get blemished by the dreaded leafminer.

http://i8.photobucket.com/albums/a29/chypmunk/C42AC88B-78F5-42A0-8AD1-9B99ACC48D93.jpg
My bounty! Looks like a lot over here, but after cooking, it only produced enough veg to fit 2 tablespoons.


http://i8.photobucket.com/albums/a29/chypmunk/2B6922BA-C6D9-4368-AF69-DF11F71DF8CE.jpg
This is after harvesting and subsequent removal of blemished leaves and weaker plants. I found out that watering with rice water daily probably wasn't enough in providing sufficient nutrients to the plants. Once a week application of diluted fresh fish blood probably helped boost the growth rate. I have swapped to once a week application of diluted Horti Fish Emulsion fertilizer. Dilute foliar spraying and watering of Horti seaweed extract will continue. However, the plants look lanky, probably from the lack of sunlight. I have no better spot to place the pot though, so I've no choice but to leave them there. Thankfully, the peat-based soil managed to retain water during these hot, dry, and windy days, so none of my plants dried up.

Wow, you harvest them so young. They will be tender as salad.
