Overall cant complain about size of bottles and what comes with it like testing tubes what was abit frustraing was how long shipping took i mean i didnt expect right away but receiving it on the last possible day for it to get to my residence was kinda lame. Overall great product helped me out alot considering i didnt know much about the ph of my water but my indoor tomato and pepper plants and also a strawberry bush has shown alot of growth since a improved ph.

Great product! the test solution is super accurate, I double check with my Digital PH test pen every time and its always within .2+/- of the PH to what the color scale comparison says it is. very easy to use and if you're a note keeper like i am eventually you can just preset the ph with a measured amount before adding nutrients to get your desired ph outcome. if i had 4 hands i'd give it 4 thumbs up.

No more guessing. Since my water pH is close to 7 I don't really need the pH up bottle.
When I run out of pH down, I will try to buy pH down only. Same with pHtest solution.
When I pH my water, I usually need to add from 3 to 6 drops of pH down to get a pH of 6.0
All in all, i'm very satisfied.

Attention produits extrêmement corrosifs, le port de gants est indispensable, par contre, fais bien le travail. Le seul problème est que tu dois y aller au "piff". Petit conseil, moins c'est mieux, mieux vaut ajuster petit à petit que de causer un choc mortel à tes végétaux

Reçu très rapidement en 2 jours. Le seul bémol s'était que le produit bleu a couler.. le seal semble en place mais le produit a effacer un peu les étiquettes. Par chance je peut encore voir les instructions. Sinon le produit est A1 je vais recommander

I would recommend this thing to anyone doing hydroponics or even just for water.... I would suggest though that you buy just the ph down in a larger size. Spending like a couple of ml for each nutrient solutions dosent leave you with much

Although I'm not sure how my new hydroponic plants will grow using this product I have to say the delivery was fast! Packaged well, described exactly in the description. I will know more in late November how the products will work.

Incredibly helpful for properly setting the ph. Just be aware you don't need much. I kept putting what I thought was s little bit and the ph would go way up or way down. Just use a drop or two, check the water, then adjust again.

These work incredibly well. If there is any shortcomings it is the colour chart which is not very distinct as to the exact PH. This is not a big problem as the PH from the colour is likely close enough.
