Nutrients — Boosters

This is the widest group in Nutrients, and not by accident: anything that is not a base feed ends up here. That puts products side by side that have nothing to do with each other, so it pays to know which corner you are looking in first.

Where most of this actually belongs

A good deal of what sits here has its own page, where it stands in context with the rest. Root stimulators like Hy-pro Rootstimulator, Atami B'cuzz Root Stimulator and Plagron Power Roots belong under Roots. Bloom stimulators, PK and ripeners such as CANNA Cannaboost, Atami Blossom Builder and Ata XL, Plagron Green Sensation and Power Buds and Aptus Super-PK belong under Bloom. Aptus Humic-Blast and Fulvic-Blast under Organic, CaMg-Boost under CalMag. If you are shopping by phase, start there.

Single elements, to correct one thing

What does have its home here are the targeted single-element boosts. Aptus sells N-Boost, P-Boost and K-Boost separately, plus Startbooster, Regulator and Topbooster for the start, the changeover and the last stretch respectively. With those you correct one shortage without shifting your whole schedule, which a complete feed cannot do. For finer control still, the straight fertilisers sit under Single Elements and Trace Elements.

Silicon works on the stem, not the flower

Atami B'cuzz Silic Boost and Plagron Silic Rock do something none of the others here do: they stiffen the cell wall, so stems hold firmer and a heavy top stays upright. That is a cumulative effect across the whole grow rather than a finishing sprint, so you start early. Silicon raises the pH of your solution noticeably, so measure after adding it and correct with something from pH Control.

For the conditions, not for the plant

One small corner addresses the room rather than the feed schedule. C-Result Celsius Beat the Heat is aimed at spells that run too warm, and C-LED at growing under LED, where the spectrum differs from a discharge lamp. No Mercy Supply CO2 tabs raise the CO2 level in a closed space, and Pentakeep Super works on chlorophyll production. These are bought against a problem you have identified, not as a standard addition.

Frequently asked questions

How many boosters do I need?
Fewer than this page suggests. The rule of thumb is one per job: one root stimulator, one bloom stimulator, one PK charge. Two products doing the same thing supply the same elements twice, which is the quickest route to burnt leaf edges.

Can I use boosters from a different brand than my base line?
Yes, that is normal and works fine in practice. Your base line's feed chart stays in charge; an add-on counts on top of it and is not a reason to raise the base dose.

Does silicon play well with everything else?
Add it to clean water first and mix it through before anything else goes in. Silicon is alkaline and can react with other elements at concentration if you pour it undiluted into something.
