One of Our Most Popular Organic Base Nutrients

Plant Magic Oldtimer Organic Grow is a premium plant food for plants grown in soil during the vegetative stage. Oldtimer organic grow is our favourite plant food for soil grown plants and it produces great results when used with Plant Magic's own Soil Supreme or any other organic soil mix. Highly recommended by us and our customers.

Plant Magic Oldtimer products encourage beneficial microbial activity in the root-zone. This increases yield and root-health. For a really flourishing microherd we highly recommend using Ecothrive Neutralise to avoid the chlorine/chloramine in tap water from inhibiting, or even killing, the friendly microbes, plus a quality beneficial inoculant such as Ecothrive Biosys when growing in soil. For an extra kick, try Ecothrive Charge too!

How To Use

How to Use Oldtimer Organic Grow

Oldtimer Organic Grow is for hand-watered plants grown in soil in the vegetative stage. Oldtimer Grow is derived from naturally sourced, organic ingredients and therefore contains particles which can clog drippers, making it unsuitable for automatic watering systems. Like most organic feeds, it will need to be used as soon as you've made it up, as organic compounds degrade more quickly than mineral feeds.

Start adding Oldtimer Grow when the nutrients in the soil are beginning to become depleted.

Always shake the bottle well before use. Add Oldtimer Organic Grow to your feed-water at a rate of 2 - 4ml per litre depending on the size and hunger of your plants.

Feed once every 2-3 waterings through the vegetative cycle ensuring that 10% - 20% run-off is achieved each time. The Plant Magic Feed Chart recommends switching to Oldtimer Bloom at the beginning of the third week of flower, though some customers make the switch earlier. A copy of the Oldtimer Feedchart can be found

As with all nutrients, boosters and additives, never mix them together in their concentrated form (i.e. straight out of the bottle). Always add each nutrient, booster or additive to your reservoir or feed water in turn, giving the solution a good stir to mix it in before adding the next one.
