How do I use PRO-MIX® HP®?

To use PRO-MIX® HP®, open the package, remove some PRO-MIX® product and place into a large tub or container. Lightly break up any clumps so that the PRO-MIX® is light and airy. Most growers prefer to add a small amount of water prior to filling containers. If you add water, add enough so that the PRO-MIX® product is slightly moist to the touch. Do not saturate. Fill flats, containers and/or pots, without compacting the PRO-MIX® in the container. Plant your seedlings, young plants, etc., then water in containers.

Great sensitive skin sunscreen
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Love this! I have sensitive skin. this did not sting my eyes, or burn my cheeks. Left no white cast. I'm not noticing any scent. It just feels like bare skin, it's not heavy, drying, oily or sticky. No pilling. Went on smooth, not streaky, looks like skin once dried down, not patchy. I hope they keep this in stock forever!

Lightweight and Effective
Style: SPF 70, Size: 8 Fl Oz (Pack of 1)
I love how lightweight and comfortable this sunscreen feels on my skin. The appearance leaves a nice glow without looking greasy or heavy. The bottle size lasts a long time and it’s very easy to apply evenly. It also smells amazing compared to other sunscreens. Definitely worth the money and perfect for everyday use.

Good!
Style: SPF 70, Size: 8 Fl Oz (Pack of 1)
Works well! Love the subtle shimmer and glow it gives me. Doesn’t leave a white cast, but definitely does feel a little oily on the skin. Smells very nice too, not that classic chemical sunscreen smell at all.

Black girl friendly!!!!!
Style: SPF 70, Size: 8 Fl Oz (Pack of 1)
I absolutely love this sunscreen! Im a black women with darker skin so its very hard to find sunscreen that doesnt make me a ghost and this one is so perfect. I tan super easy and dont want bad tan lines and this stops me from tanning when im just in regular clothes. This leaves my skin feeling super hydrated and it gives me such a beautiful glow im so obsessed i will NEVER use anything else. It smells ok, its not the typical sunscreen smell it has a slight fragrance to it. I have sensitive skin on my face and i use this on my face and i dont break out! Which never happens when i use a new product on my face, i typically break out. It goes on white but after rubbing it in after a few seconds it turns into this gorgeous golden glow.
