Heavy 16 Feeding Schedule

About Heavy 16

Heavy 16 is a two-part base — A and B, in Veg and Bloom — and the whole pitch is that you do not need much else. The formulations already carry the calcium and magnesium most programs sell you separately, so the shelf stays short and the mixing order stays simple.

Where it earns its reputation is consistency. Growers who run it tend to keep running it, because the EC lands where the chart says it will and the plants respond the same way every cycle. The additives — Prime, Fire, Foliar, Roots — are genuinely optional rather than required to make the base work.
