#1. Clear your system

It’s so fundamental however so many individuals overlook that if a system isn’t stored clear, dust and dirt can construct up and block pipework. We advocate frequently checking and cleansing your float switches within the mind pot, eradicating any sediment or particles that begins to construct up in your reservoir and as well as, rinsing out your reservoir between refills. It’s additionally a good suggestion to make use of a sterilizing agent to totally clear the system, in any other case you could possibly have future points.

#2. Guarantee your pipes will not be blocked by your roots

One of many largest points that flood and drain customers have is that roots find yourself blocking the feed pipe. It is because these methods each fill and empty via the identical tubing. To make sure this doesn’t occur, our specialists advocate rotating the inside pot by 45 levels (a couple of quarter flip) in the identical course each couple of days. Have you ever’ve bought an IWS Flood System? These include copper root management discs that may stop the roots from going wild within the water and we’ve discovered these are particularly efficient at stopping blockages from forming.

In the event you suspect you’ve a blockage brought on by your roots, merely pour round 5-Eight litres of nutrient answer in from the highest of the container. In fact, if the answer drains shortly, you seemingly don’t have a blockage. Nevertheless, if it sits and takes time to empty, you seemingly do have a blockage. It ought to be famous, nonetheless, that this check solely works properly with clay pebbles, perlite, growstones or different fast-draining media. With some other medium the water retention might trigger it to empty slowly no matter any blockage. If it seems you do certainly have a blockage, merely take away the inside pot and examine the tube for any roots or particles.


#three: Choose your rising media appropriately

Now relying on what you might be rising, this varies a bit. Many individuals will inform you it comes down to non-public desire. Nevertheless, take into account that you want Low to Medium WHC (Water Holding Capability) and Excessive AFP (Air Stuffed Porosity) as key parts to your media choice. In any other case water retention might be too nice to be efficient in your system.

In the event you’re flooding extra incessantly, our specialists counsel utilizing clay pebbles. Easy and simple to make use of however tried and examined. And as an added side-effect, it’ll additionally take up the nutrient combine. Permitting the grower to extend the frequency of watering. This in flip lets you flood your system extra incessantly with out fear of over-watering.

In the event you’re flooding much less typically, we advise you strive mixing coco along with your clay pebbles/perlite at roughly a 60/40 clay police/coco break up. This can be a frequent tactic but it surely works. The coco combine holds much more water which suggests you gained’t should flood your system practically as typically. The advantage of flooding much less typically will not be having to hurry when responding to important failures within the system. One other profit is that it’s very best for growers who can’t are likely to their vegetation every day.

Perlite acts equally to clay balls, in that it’s a quick draining medium. It has much less water retention than clay pebbles nonetheless so that you’ll want a good greater watering frequency to compensate for this.

Growstones are one other nice different and are manufactured from 100% recycled glass. The wonderful thing about them is that they resist compaction like clay pebbles and are extremely porous in nature.

We don’t advocate utilizing an excessive amount of extra coco than what we steered above because it might trigger your media to remain moist for too lengthy. This defeats the aim of flood and drain, as roots will turn out to be water logged. This in flip will increase the possibilities of points similar to root rot taking maintain.

As counter-intuitive as it might be, flood and drain methods are genuinely designed for frequent flooding because the vitamins are provided freshly. When this nutrient answer drains, it attracts recent air into the foundation zone. This combines a wealthy nutrient provide with a stable provide of oxygen will guarantee you’ve constant fast development and bigger yields.


#four. Optimise your Flood Cycle Parameters

Once we say ‘parameters’, we imply three typically. The primary parameter is flood frequency, or how typically your system is flooded. This might be effected probably the most by the dimensions of the plant itself, the local weather, the plant’s water necessities and the medium used to develop in. Within the overwhelming majority of instances, once you take your vegetation out of propagation you’ll discover your crops all of the sudden are in a better warmth however decrease humidity surroundings. This implies their water necessities will enhance. In case your rising media lacks water retention, you’ll have to flood extra incessantly with a view to preserve an sufficient quantity of nutrient answer throughout the substrate.

As a normal rule of thumb, your flood peak ought to by no means climb greater than the peak of your rising media. We advocate this straightforward step sequence to make sure you get your flood peak excellent:

Solely add your root management disk and washed clay pebbles following your system being arrange.
Fill three quarters of every pot along with your chosen media.
In case your vegetation are within the vegetative stage, fill your water tank with the nutrient combine at a focus of two CF greater than throughout the propagation section.
Guarantee your timer is ready to the longest attainable time, in minutes and wait to your mind to begin filling the containers.
If the water ranges start rising greater than the rising media then merely add extra media.
Press down on the media gently along with your hand to make sure it isn’t floating up within the water.
Soak for round 45 minutes, then drain the system.

Your flood cycle ought to by no means be held any longer than 10 minutes. As soon as draining has accomplished, set your flood length up and make sure that the pH is ideal. If it isn’t then alter your nutrient combine. Lastly, begin the flood cycle once more to see how lengthy it takes for the max flood peak to be reached and in the event you’re utilizing clay pebbles that haven’t been blended with coco, add a pair further minutes to the cycle.

This technique of working our your flood peak is very efficient as a result of in instances the place the flood is uneven, the flood peak might be completely different for every container and this manner lets you precisely work out how a lot media is important for every.


#5. Transpiration earlier than irrigation

Merely put, wait to your vegetation to begin utilizing any remaining water within the rising media earlier than you flood them once more. This interprets to having your first irrigation round 30 minutes after the lights go on. This additionally implies that typically, you need to solely should flood throughout the lights on interval. By no means when the lights are off. But it surely ought to be famous that roots ought to by no means be bone dry. so you could want a single irrigation interval when it’s lights off however nonetheless heat, but it surely ought to by no means be multiple.

#6. Younger vegetation ought to solely be positioned round 2.5cm into the medium

In the event you place younger vegetation too deeply into the container you would possibly discover that your flood peak will utterly stand up over the transplant block and this may trigger severe points. However in the event you plant them shallowly to start with, the nutrient answer ought to solely attain the underside of the transplant block as soon as it reaches most peak.

Along with this, we advocate exposing the roots when you’ve positioned your vegetation by shifting the plastic wrapped across the transplant blocks up the block by 2.5cm as properly. It ought to be roughly in step with the highest of your medium.

#7. Match your nutrient combine’s power to your local weather

Like people, vegetation drink extra water when it’s sizzling. In hotter, drier climates, like throughout the summer season when your room will seemingly run at across the 28 diploma centigrade mark with an RH of 45%, your vegetation will use extra water and consumption much less of the nutrient combine. Throughout this era, the nutrient power ought to be dropped considerably. Your vegetation will want flooding extra typically, normally round each hour. We advise utilizing a CF Truncheon by Bluelab to make sure your nutrient power readings are correct.


#Eight. Have a Clay Pebble layer of round an inch on the backside of your container

Actually easy tip, however the backside of the container is the place nearly all of your water will keep. Thus it is sensible to have this skinny layer which’ll enable for it to empty away extra simply. We advocate this even in the event you’re already mixing clay pebbles with coco as this backside layer makes all of the distinction.

#9. Choose your containers correctly

This differs primarily based on what media you’re utilizing to develop your vegetation. Bigger methods of 36 pots plus would require punch pots for use. Smaller methods, conversely, will want aqua pots that are web pots which have been optimised for flooding and root improvement. In fact that is all assuming you’re utilizing simply clay pebbles.

In the event you’re utilizing 70/30 or 60/40 coco combine with perlite or clay pebbles nonetheless, we advocate utilizing tradition pots. These have a web base designed particularly for rising in finer media. We advocate additionally putting root pouches inside of every of the inside pots to stop roots from extending out into the pipework.

#10. Improve to an IWS Professional System

Primary methods are nice. That’s, nice till you hit a sure important mass. Then it turns into “Go massive or go residence”. The IWS Professional system is right in the event you’re rising greater than 12 vegetation. First, you get a bigger pump and 25mm pipes which permits pots to be refilled at a a lot greater velocity. Second, the bigger pipes additionally make sure that there’s a lowered danger of blockages brought on by roots. This can guarantee you’ll get a way more even development throughout.
