How to make ootuka House hydroponic fertilizer water

Otsuka House (OAT House) (OAT AGRIO CORPORATION)

Benefit
The price is cheap and there are many types of fertilizers and the growth of vegetables is good. (The price is about half the price of Hyponica) It is useful for people who do full-scale hydroponic cultivation.

Demerits
It's a little bothersome to make fertilizer water, and it's a bulk buy if you buy it because you don't sell it in small portions.
(Available for individuals who sell in small lots.)

What you prepared
★ Otsuka House No. 1 (OAT House No. 1) 300 g
★ Otsuka House No. 2 (OAT House No. 2) 200 g
★ Otsuka House No. 5 (OAT House No. 5) 50g
★ 2 liter plastic bottle size 2
★ 1 bottle of plastic 500 ml
★ Syringe (purchased at the pesticide center in the home improvement center)
★ Measuring cup (It is prepared to measure up to 2000ml with Daiso (One Dollar shop))
★ Weighing Scale
★ Water ★ pot

Do not use the concentrate as it is, as it is diluted from the concentrate to make fertilizer water.

Make concentrated liquid from the state of powder.
※ It seems that tap water is suitable for the water used.
Please do not make it with well water or mineral water (from the point of purchase) and it was noted.

Most vegetables grow well with solutions that are 2000 to 4000 times concentrated.
In the case of hydroponic cultivation of strawberry, when the fertilizer water is thick, the tip of the strawberry leaf becomes dark and eventually root rot is caused and it withers.
This was a symptom of excessive nitrogen, which roughly occurred when the concentration of fertilizer was too high.
Some vegetables are weak against such fertilizers. It may be better to check the concentration of fertilizers before growing.

First of all,

Put tap water in a pot and boil it for a while to cool.

※ The water used seems to be suitable for tap water. Please do not make it with well water or mineral water (from the point of purchase) and it was noted.

Next, prepare 300g of Ootsuka House No. 1 to make 2 liters of No. 1 concentrate.

(The proportion of the volume of Ootsuka House No. 1 concentrate is 150 g per liter of water)

Put it in a measuring cup and pour 2 liters of hot water (boiling tap water and a little chilled water).

I added 2 liters of hot water and stirred it.

Ootsuka House No. 1 became a slightly yellow liquid. (*^▽^*)

Pour into a 2 liter pet pot

And I put a label of 1 (the meaning of Ootsuka House No. 1) and the concentrate of Ootsuka House No. 1 is completed.

Then make a 2 liter size concentrate of Otsuka House No. 2.
Prepare 200g of Otsuka House No. 2 powder.

(The proportion of the volume of Ootsuka House No. 2 concentrate is 100 g per liter of water)

Put it in a measuring cup and pour 2 liters of hot water.

Stir well until the powder is gone.

The concentrate of Ootsuka House No. 2 is clear.
Put this in a 2-liter plastic bottle and put a label on it. (*^▽^*)

Finally, make a concentrate of Ootsuka House No. 5.
No. 5 is prepared 500g, so prepare 50g.

(Make 500ml for not using too much.)

(The proportion of the volume of Ootsuka House No. 5 concentrate is 100g per liter of water)

Put Ootsuka House No. 5 into a measuring cup and pour 500ml of hot water.

The concentrate of Otsuka House No. 5 was coffee-like color (＾◇＾)
Stir it well and put it in a 500ml plastic bottle.

Label 5 and complete the 500ml Ootsuka House Concentrated Solution. (＾◇＾)

The concentrate of Ootsuka House No. 1, No. 2 and No. 3 was completed.
We change concentration of fertilizer water to make by kind of vegetables to bring up from this concentrate and use.

※ Fertilizer water used for most vegetables is a 2000-fold dilution of this concentrate.

(1000-fold fertilizer water: 10ml of concentrate 1, 10ml of 2, and 0.25ml of 5 per liter of water) (2000 times fertilizer water: 5ml of concentrated solution No. 1, 0.5 No. 5ml, No. 5 0.25ml per 1 liter of water) (4000-fold fertilizer water: 2.5ml of No. 1 concentrate, 2.5ml of No. 2, 0.25ml of 5 per liter of water, etc. ※ The concentration of fertilizer water used is written in the corner of each vegetable, so please refer to it for reference.
