HWS Advice

About HWS

More and more users are reverting to hand-watering as cost becomes an issue, for this reason IWS have gone back to basics with their latest system, the HWS.

Hand-watering is arguably the purest and simplest way to grow, making it ideal for novices. The system can be run as independent pots though it works much better when connected together into a system with a control unit.

Available in 3 sizes 10 ltr – 16 ltr and 25 ltr , the HWS can be tailored to suit most users.

Our 3d movie section goes into detail on system assembly and how each system works.
Here we will try to give you advice on all aspects of using the system, giving you a better chance of success.
 

Which growing media?

When hand-watering, it is important that your chosen growing medium has free drainage with good oxygen to water retention. A good soil mix or Coir mix seem to work great in this system.

Planning your grow schedule

In order to get the best possible result from your HWS system we recommend a good 20% run off of nutrient solution with every feed and a full saturation of the growing medium at least once a day and allow the growing medium to drain and loose most of its water before feeding again.

Environmental considerations

As with any growing system, your nutrient strength and watering should reflect your grow room environment. In Summer time when there are hot and dry conditions this will cause the plant to use more water and less nutrient. Consequently the nutrient strength should be set lower than usual to account for the nutrient strength rising in the reservoir. In these conditions the pots should be flooded once an hour.

In the same room during winter the room runs at 26°C with an RH of 60%, these more favourable conditions, that aren’t putting environmental pressures on the plants, will mean higher nutrient strengths can be used It is therefore extremely important to consider the effect that your grow room environment will have on your plants and adjust your feeding strategy accordingly.
 

Maintenance

Avoiding root blockages
Roots growing out of the pot can sometimes cause blockages in the drain-pipe. To avoid this you should get in amongst your plants, routinely turn the inner pot round 45° in the same direction every 2-3 days. This will make sure roots stay away from the tube and may also produce a more even growth pattern.

Checking for Root Blockages
If you suspect your pots or pipe-work may be blocked you can confirm it by quickly flooding the pot, If the solution drains away freely it’s ok, if it sits there and takes a long time to drain you most likely have a blockage. If your pot is blocked you should remove the pot and check the inlet/outlet tube for roots or debris.

Minimising System Problems
Most system problems come about through not keeping a clean system. You must make sure your float switches in the brain pot do not become dirty or clogged with any growing media. Each time you refill the reservoir a quick rinse with fresh water over the switches will help prevent problems. If you do notice sediment or debris in the reservoir or brain pot, remove or clean it immediately.
