CalCarb

CalCarb is a revolutionary calcium carbonate foliar spray proprietarily-derived from a naturally occurring compound. It utilizes a new form of nanotechnology which processes the compound to such a fine size that it is able to permeate the foliage of plants. Once inside the cell walls, CO2 is released as both calcium and usable carbon dioxide, increasing photosynthesis levels three-fold.

Both calcium and carbon are critical to plant development. Calcium is generally supplied through the soil and carbon enters the plant as carbon dioxide which is necessary for photosynthesis to occur. CalCarb is a unique form of a simple and very common compound that contains both calcium and carbon. Calcium carbonate or CaCO3 is used in agriculture throughout most of the world to adjust soil pH levels. But CalCarb is an unusual form of calcium carbonate that is highly unstable, converting to calcium oxide (CaO) and carbon dioxide (CO2) rapidly when applied to the foliage.

This unique phenomenon increases calcium availability to plants through the foliage, but more importantly, the CO2 levels directly outside and inside the stomata can rise threefold which is near the optimum for photosynthesis efficiency.

Easily Applied to the Underside of Foliage!

Stress Reduction and Plant Rescue - Forget to water? Didn't remember to bring that tender houseplant in before the first cold snap? If it is not too far gone, treat it with CalCarb and you may be able to rescue it. CalCarb helps in recovery by increasing photosynthesis in the foliage that is not too seriously damaged and by raising the surface pH of damaged foliage which deters airborne pathogens from taking advantage of the weakened cellular tissue.

May Prevent Tomato End-Rot and Powdery Mildew.

Foliar Spray For Indoor and Outdoor Use.

Established Plants:

Add 1 tsp per quart (liter) of water (1 tbsp per gal) into the sprayer. and mix well. Spray foliage focusing on the underside of plant leaves.

Note, Calcarb leaves a beneficial white residue of natural calcium. it may be rinsed off after 36 hours, but let on will achieve the best results.

Calcarb is best applied alone, wait 36 hours before applying other foliar nutrients.

Clean sprayer after every use.

Flowering & Fruiting Plan:

Add 2 tsp per quart (liter) of water. Mix well and add to the sprayer. Spray focused "pop-shots" on the underside of outermost leaves.

Calcarb need only be applied to 6-12 leaves. No need to saturate the entirety of foliage.

Avoid fruits and flowering bodies!

Not a great experience but a fine product
Color: Black, Size: 4 Panel Basic
not enough screws were included to make the wall. I was able to locate more screws to finish building-so I didn’t have to return the product- but it was a pain and I got lucky finding the pieces I needed but it could’ve been a fail and a returned product

Useful, simple room divider
Color: White, Size: 4 Panel Basic
All the pieces were accounted for, and some even had extra pieces, maybe just in case they need changing. It was a bit like putting together a piece of IKEA furniture, though I went slower than usual so as not to make any mistakes. It wasn’t too hard to put together myself, and helps give my studio apt a feeling of space and privacy for my bed. I only wish it had a lovely Japanese design on it, but it does amazingly seem to match the wall color.
