Description

BIONOVA k20Voedselveilige minerale meststof 20% kalium, Bionova K 20. Planten hebben tijdens de rijpingsfase een grote behoefte aan kalium. Kalium speelt een belangrijke rol bij de osmoseregeling, het openen en sluiten van de huidmondjes, de eiwitsynthese en de werking van enzymen. Dit resulteert in een hogere kwaliteit fruit bloemen, verbeterde stevigheid en drooggewichtgehalte. Planten absorberen direct alle voedselwaardige mineralen in de Bionova K 20

Voedselveilige minerale meststof 20% kalium, Bionova K 20. Planten hebben tijdens de rijpingsfase een grote behoefte aan kalium. Kalium speelt een belangrijke rol bij de osmoseregeling, het openen en sluiten van de huidmondjes, de eiwitsynthese en de werking van enzymen. Dit resulteert in een hogere kwaliteit fruit/bloemen, verbeterde stevigheid en drooggewichtgehalte. Planten absorberen direct alle voedselwaardige mineralen in de Bionova K 20 waardoor u optimale controle heeft over uw planten.

Wat is BioNova K 20?
Naast de basiselementen N en P is ook Bionova K 20 (Kalium) cruciaal voor elke teelt. Kalium maakt cellen steviger (waterhuishouding) en bevordert de bloei. Kalium speelt ook een belangrijke rol bij de celvorming, de osmoseregeling en de koolhydratenhuishouding. Verder is kalium belangrijk voor het openen en sluiten van de huidmondjes, die de afvoer van overtollige warmte mogelijk maken.
Een tekort aan kalium manifesteert zich wanneer de plant de huidmondjes onvoldoende opent voor verdamping om af te koelen. Hierdoor ontstaat chlorose aan de randen van de bladeren, die zich in een later stadium ontwikkelt tot necrose (dood). Bij een teveel aan kalium zal de plant in zijn ontwikkeling worden geremd en vervolgens donker worden. Een teveel belemmert ook de opname van andere kationen (Ca en Mg), wat veroorzaakt wordt door antagonistische effecten.

Love this sunscreen
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I would love to buy again, but I go through sunscreen, I have to find a little less expensive one. No burn, dewy not greasy look. Great for mature skin. No fragrance, works well, melts right in the skin. I do love this product and the spray too!

Light and works with no eye stinging.
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
I love this sunscreen. I wear co tact’s and most sunscreen ends ups burning my eyes. This does not! It has a nice cucumber smell and it’s not sticky or heavy. By far the best face sunscreen that’s light, smells nice, doesn’t burn my eyes and works.

My all time fave sunscreen!
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
This is the best sunscreen! Does NOT burn my eyes like 95% of other sunscreens do. Does NOT break out my sensitive skin, or my sister who has the most sensitive skin ever! It goes on smoothly due to its nice texture, does NOT feel greasy. Wears great under foundation as well. Thank you Coola for such a great formula at an affordable price. I have turned so many 'sunscreen snobs' into fan favorites of this as well. If you haven't tried it, you should!

good for non-white skin
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
Moisturizing, non-sticky, works for my sensitive skin. It's transparent and doesn't leave a white cast on my light brown skin. Smallish size is good for travel and purse. It's a little shiny; wish it came in matte.

Very effective
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I love this sunscreen for your face. It doesn’t feel oily. It doesn’t stay white on your skin. It absorbs and it really protects it nicely. I put it on every morning before I walk my dog in the sun and I’m out for normally at least an hour so it’s a really nice sunscreen and I would definitely give it a try.
