If you are growing flowers in your hydroponic garden, the chances are that you are looking for bigger, better and heavier blooms – and hydroponics will allow you to achieve this, you just need to be patience and get the hang of a few things. Of course bigger flowers are always better and this is why many hydroponics growers choose to grow them in their systems, but did you know that when flowers grow in size they also usually boast deeper colours, stronger fragrances and more!
The trick is to make proper adjustments during the flowering stage of development – this is the stage that matters the most. Here are some top tips to enable you to grow bigger and better flowers:
Check your phosphorus to potassium ratio – Phosphorus and potassium are essential elements when looking to grow a successful harvest – this is something which many of you will already no doubt know. These elements help to speed up plants metabolism and cell division which lead inevitably to mammoth flowers. But what is the best ratio?
Most popular flowering boosters that are sold are PK 14/15; however this does not mean that it is the greatest ratio. A flowering booster with this much phosphorus can put flowers at risk of phosphorus excess. In reality the best ratio would be something along the lines of PK9/18, containing much more potassium than phosphorus.
Switch to a 12/12 Photoperiod–Most hydroponic growers follow the same photoperiod routine, keeping their lights on for 18 hours and then turning them off for 6. While it’s true that light is essential for growing, during flowering stages you actually do not need to have your lights on as much. Changing your photoperiod to this will not only allow your flowers to grow larger but will also allow you to save money.
Use red spectrum lightsonly – While your flowers are in the flowering stage, this is when your plants are going to benefit the most from a red spectrum light, such as high pressure sodium. You might also want to think about only using red LED lights; the advantage of these is that they have a low heat output but if you have the best fans in place and a closed loop extractor, you are probably not too worried that your hydro-garden is at the risk of overheating.
