HGV Base is a dry, water-soluble calcium and nitrogen concentrate for two-part feeding programs. It carries 14.5% all-nitrate nitrogen and 19% calcium, and it runs at the same 15 mL/gal dose through veg and flower while you swap the companion part from Growth to Flowering. The all-nitrate formula avoids the salt buildup that ammoniacal and urea nitrogen can cause. It suits growers running a two-part regimen who want one steady base and a separate calcium source, and it has to stay in its own jug because calcium and phosphate precipitate when concentrated.

HGV Base is a dry, ready-to-mix concentrate with an NPK of 14.5-0-0. It supplies 14.5% nitrogen, all in nitrate form, and 19% calcium. The nitrogen is fully water-soluble, with no ammoniacal or urea forms.
The Base dose stays the same from veg through flowering at 15 mL/gal. It is the calcium and nitrogen part of a two-part feeding program. During veg, pair it with HGV Growth at 30 mL/gal. During bloom, switch to HGV Flowering at 30 mL/gal and keep the Base unchanged.
Keep the Base concentrate in its own jug. Calcium and phosphate precipitate when concentrated Base contacts Growth or Flower. Add it to the reservoir last, then check pH. The same dose is used in NFT, DWC, flood-and-drain, rockwool, coco, and peat-based soilless mixes.
