Green Planet Horti Late Cal
Late bloom is when the crop bulks up, and Green Planet Horti Late Cal is a calcium feed made for that stretch. It's a zero-nitrogen dry powder that brings highly bioavailable calcium and essential micronutrients into the feed while the flowers fill out. Green Planet say it supports strong bulking, maintains plant health and encourages vigorous development, all without adding any nitrogen at this stage of the cycle.
It's part of the Horti Commercial Line, which is built for growers who mix their own solution from dry ingredients. In the commercial late-bloom feed it works alongside Horti Late Bloom, which brings phosphorus, potassium, magnesium and sulphur. Horti Late Cal has no nitrogen in its formula, which makes it one part of that late-bloom feed and not a complete feed on its own.
Calcium is the main job here, and it matters at bulking time because plants build it into their cell walls as new tissue forms. It travels to growing tissue with the water the plant draws up, and once it's laid down it stays put. Swelling flowers can't borrow it from older leaves. They depend on what's in the feed each day.
The real difference is zero nitrogen. You can keep calcium in the late-bloom feed without this part of the mix adding nitrogen. That leaves calcium and nitrogen as two separate decisions when you build the feed, and it matters late in flower, when extra nitrogen keeps pushing leafy growth while the plant should be filling flowers.
Horti Late Cal is a white powder that dissolves completely in water. It draws its calcium from two sources, calcium chloride and calcium citrate, and carries its micronutrients beside them. Since Horti Late Cal goes fully into solution, you can stir it straight into feed water or make it up ahead of time as a concentrated stock.
With Horti Late Cal, the order of mixing counts for more than anything else in the tank. Horti Late Bloom carries the phosphorus and sulphur for the same feed, and that's why the two concentrates never meet directly. Concentrated calcium mixed with concentrated phosphate or sulphate can come out of solution as insoluble calcium phosphate or calcium sulphate. Nutrients locked into a solid at the bottom of the tank never reach the roots.
Calcium chloride is also hygroscopic, which means it pulls moisture from the air. That's why storage matters with Horti Late Cal: powder that takes on water clumps and gets harder to weigh out accurately.
