DIRECTIONS
For spectacular Reiziger results. Feed only as directed.
Reiziger Grow Food A&B is 275% stronger than your old brand. It is ultra pure and super concentrated. It can easily burn plants when over-dosed. To start your grow stage safely for the first two weeks with no risk, add A&B at 0.4 mL/L/qt.

GROWTH STAGE 1
For rooted cuttings.
Reiziger is super concentrated and can burn plants when over-dosed. To start your grow stage safely for the first two weeks with no risk, add A&B concentrates in equal amounts at the rate of 0.4 ml/L/qt. If you are an experienced grower, start irrigating during the first 2 – 3 weeks with an EC of 0.2 – 0.6 mS/cm higher than the EC of the tap water. Do this by filling the nutrition tank with water. Shake Reiziger Grow Food A&B well. Add A&B concentrates in equal amounts at the rate of 0.4-1.2 ml/L/qt. Add boosters. Adjust EC. Let stand for several hours before adjusting pH to 5.8. Irrigate until drainage appears. To accelerate new root growth and help save plants, add Reiziger Root Booster to the nutrition tank at the rate of 1 ml/L/qt.
The suggested EC levels are based on tap water of 0.0 mS/cm. If your tap water EC is higher than 0.0 mS, then your recommended EC will also be higher. E.g.: Suggested EC is 0.2 mS and your water is EC 0.5 mS then your EC will be 0.2 (EC suggested) + 0.5 (EC of tap water) = EC 0.7 mS/cm.

For the next 1 – 6 weeks, irrigate with an EC of 0.3 – 0.7 mS/cm higher than the EC of the tap water. Shake Reiziger Grow Food A&B well. Add A&B concentrates in equal amounts at the rate of 0.6 – 1.4 ml/L/qt. Add boosters. Adjust EC. Let stand for several hours before adjusting pH to 5.8. To significantly reduce the growth cycle in rapid growing plants add Reiziger Root Booster to the nutrition tank at the rate of 0.5 ml/L/qt. To renew, rebuild and strengthen plant appearance and ensure a healthier, stronger more robust plant, add Reiziger Grow Booster at the rate of 2.5 ml/L/qt.
The suggested EC levels are based on tap water of 0.0 mS/cm. If your tap water EC is higher than 0.0 mS, then your recommended EC will also be higher. E.g.: Suggested EC is 0.2 mS and your water is EC 0.5 mS then your EC will be 0.2 (EC suggested) + 0.5 (EC of tap water) = EC 0.7 mS/cm
Recommendations. Made simple.
Take control of your nutrients. Experimentation has its place, however, if you are just starting out, resist the temptation. Reiziger Grow Food A&B is 275% stronger than your old brand. You need smaller doses than other products. It can easily burn plants when over-dosed. Decrease nutrient strength if plants display signs of tip burn when feeding aggressively, or if cultivating in particularly bright, hot or dry climates. Never mix A&B together undiluted. Always measure EC first then pH with test meters. If you are serious about hydroponics and really do want to enjoy twice the yield of soil growers, you should purchase the necessary nutrient testing meters. This one simple step ahead in the art of growing will assure better results in every size and type of hydroponic system. In the long run, it’s how you manage your solution and the system that will determine the success or failure.

The innovative dosing system is the first closed liquid dosing system in the world and enables the user to dose a specific amount of liquid in only three steps. No longer is it necessary to orientate the packaging or squeeze the reservoir.



DOSING SOLUTIONS
Turn the bottle upside down.
To dose a specific amount of liquid start by turning the bottle completely upside down to fill the dosing chamber.

Tilt the bottle for the required dosage.
For 40 ml, follow the line to the left of the dosing chamber and tilt bottle. Likewise for 20 ml, follow the line to the left of the dosing chamber and tilt bottle.


Unscrew the cap.
Unscrew and remove the cap. This closes the valve between the dosing chamber and the bottle.

Pour out the liquid.
Your product is now dosed and ready to use.

For big, productive Reiziger Results. Water it right.
The frequency of feeding depends on the grow room temperature, evaporation and the water supply in the medium. Establishing a balance between the water holding capacity of a medium, aeration and drainage is a key to optimum plant growth. Generally, we recommend giving five-litres/ m²/ day for fully-grown plants.

Rockwool.
A general rule for Rockwool slabs in trays is that three daily one minute feeds (50ml) should be sufficient during the first week; then six to ten (50 -100 ml) feeds per day – starting several minutes before the lamps have been turned on and two hours before they are switched off. Rockwool substrates hold liquid while still draining well, however it is still possible to over water. For optimum results regularly check the moisture content of the medium and ensure it is not water logged. Only water the plants during the day period.

Perlite.
The amount of irrigation water to apply is perhaps more important than how and when to irrigate. A general rule of thumb to follow in irrigating greenhouse crops is to apply 10-15% more water than the container will hold. Only water the plants during the day period.

Coconut coir pith.
A general rule is that one daily feed should be sufficient during the first few weeks; then two feeds per day – two hours after turning the lamps on and two hours before switching them off. Do not water the plants too often or give too much water. By reducing the watering frequency, optimal water replenishment is established. This improves the capacity of the coconut substrate to absorb all the nutrients, optimises the drainage and air in the medium and prevents accumulation of salts within the coconut substrate. If the EC of the irrigation water is higher than 0.6 mS/cm, then it is better to increase the water dosage until drainage of 20% has been reached (1/5 of the irrigation solution has to leave the medium again). If the EC of the irrigation water is lower than 0.6 mS/cm, a lower drainage of 10% will suffice. Reiziger Coconut Coir Pith holds liquid while still draining well, however it is still possible to over water. When growing in cocoponics, determining pH and EC from drainage water is not a true indication of the coconut substrates value. For optimal results, you are encouraged to use the 1: 1.5 extraction methods.

Expanded Clay.
A general rule of thumb to follow in irrigating greenhouse crops is to apply 10-15% more water than the container will hold. Frequency of application will depend upon plant size and greenhouse temperature, but will vary from one 15 minute feed every hour while the lights are on during the first weeks of growth; then one 15 minute feed every two hours – starting several minutes before the lamps have been turned on. Only water the plants during the day period.

Recirculating systems.
Compared with cultivating on substrates with high nutrient and water buffers, such as coconut coir substrates, recirculating systems require closer monitoring of the feed and the plants because they contain insufficient nutrient buffer which means changes to the nutrient solution have a direct and sudden impact on the plant. The feed reservoir must contain at least 5L per plant. The more feed there is available for the plants, the smaller any fluctuations in the pH and EC will be. Under normal circumstances renew feed every 7 -14 days. If not renewed in time the desired balance between the different nutritional elements will be severely disrupted. Between changes, the feed reservoir needs to be regularly topped up to its original level when 25 -50% of the feeding solution has been used. It’s best to use a solution that is approximately half as strong as the original feed solution. In circumstances where evaporation is a concern, the reservoir is best topped up with tap water e.g. high temperatures and low humidity. This way evaporation can take place easily while the nutrient solution’s EC is prevented from rising.
