Recent History
Cultivars introduced from China during the Taisho era

Suitable temperature for germination 25-30 ℃ (anaerobic seeds)

Sunlight conditions More than half a day is required

Daylight hours About 5 hours

Suitable temperature for growth 25-35 ℃

Consecutive crop failure Not relevant because it is pumped hydroponics.

Watering Refilled about 2cm in the morning.

Hydroculture fertilizer concentration Otsuka House (4000 times) Hyponica (1000 times)

Days from sowing to harvesting 140 days (hydroponic air pump)

Crop yield 1 (not sweet enough)

Points to watch out for growth

Be careful not to reduce the amount of fertilizer water in summer.
Seeding is a hotbed sowing in March (direct sowing is ideal after May holidays)
Raise in a sunny place as much as possible
Because it is a home garden, I tried to grow one vine per 2 vines (child vines).
Since aphids were attached, I looked carefully at the back of the leaves.
At first, I grew up at Otsuka House 2000 times, but it died because of excessive fertilizer.
(Foot fertilizer water diluted 4000 times seems to be better.)
I made a fruit with the second flower. (Because it was written in the book that the first flower grows slow)

What you want to try in the future.

I want to grow with soil hydroponics.
The cultivation instructions stated that it was sweet and full of flavor, so this time I would like to grow it without dying, paying attention to the fertilizer concentration.

Standard of each watermelon fertilizer water(Hydroponics)

When growing at Otsuka House (OAT House) From germination to fruiting
Concentrate 4000x
(For each liter of water, each concentrate is 2.5ml, No.2 2.5ml, No.5, 0.25ml)

When the fruit begins to grow
(Looking at the actual growth, if the seedling is good, you can keep the concentrate 4000 times.)
Concentrate 2000x
(Each concentrate is 1ml 5ml, 2ml 5ml, 5ml, 0.25ml)

I couldn't forget the deliciousness of the small watermelon harvested last year, and I wanted to grow watermelon again this year.
Anyway, I thought that there were no watermelons that would have an impact and would be interesting to grow, so I looked into various things ...

I found interesting watermelons. (*^▽^*)

One is Jumbo Saijo, and kahou ( Small watermelon ), which we are raising this time.
I'm looking forward to it because the cultivation manual says that the pulp is yellow and has a natural quality, sweet and strong.
(*^▽^*)

From purchasing kahou watermelon seeds

If you are looking for a variety of things, Noguchi Seed Research Institute sells seeds so try to buy them It was.

15 tablets for 308 yen (as of 2019),

It was a conscientious store with post-payment fees. (*^▽^*)

This time, I will try to grow it with pump-type hydroponics that has been successfully grown once with red temari (small watermelon).

Starting sowing on March 17, 2018.

The optimum temperature for germination of Jiabao is 25-30 ℃.

Some days in mid-March 2018 did not exceed 20 degrees Celsius, so I left it in a warm room until it germinated.

21 days after sowing,

Is the temperature still low?
It seems to grow slowly even after germination.

35 days after sowing,

The middle of April. It became warm, and the shoots were growing and alive.
I'd like to transplant to pump-type hydroponics next week,

44 days after sowing,

After entering GW, the temperature was warm and stable, so I transplanted it to a pump-type hydroponic plant.(*^▽^*)

49 days after sowing,

It has been a week since I transplanted it to a pump-type hydroponic plant.
I feel that the leaves are a little withered and the bottom is loose.
I'm worried. (;´･ω･)
