 A-Grade Hydroponics Top Tips #2

In part two of this tutorial Jase is giving out some crucial growing tips that a lot of growers overlook, by implementing them you will eventually form good habits in the grow room allowing you to grow the best possible crop, grow after grow!

 

TIP 1 – WATER CONTROL! CALIBRATE YOU EQUIPMENT (EC & PH)

Every day we are doing something in our growing space, that constant maintenance pays off in the form of healthy crops abundant in flowers. Sometimes, it doesn’t go to plan though and usually we can go back and determine that human error was the cause. The same thing goes for mixing up nutrient rich solutions, you may have memorised what the value of each dose represents in pH and EC, but do you check your run off?

Do you know what your pot/rootzone is ‘holding’? To put this simply, if the EC range of the pot is over 2.4-3.0 then no matter what you feed them they will only consume water because of the accumulation of food which only increases the EC and acidifies the water.

Always check your pH and EC measurements from your run off and you will have much better results.

 

TIP 2 – LIGHTING CONTROL! NO LIGHT METER MEANS YOU DON’T KNOW

Artificial lighting systems for indoor growing are intense. High-end LED lighting for example outputs serious amounts of light energy and very minimal thermal energy.

The light that leaves a fixture is measured in PPF(Photosynthetic Photon Flux), light hitting plant canopy is measured in PPFD (Photosynthetic Photon Flux Density) and over a specific photoperiod (duration) the PPFD measurement (per second) is multiplied to give us our DLI (Daily Light Integral) reading. If you’re already confused, then not having a light meter is going to be detrimental to your success.

Not knowing the amount of light your plants are receiving sort of negates growing in a precision based environment, imagine if you actually knew the exact number to expose your plants to in a specific phase, the purchase of one of these units will send your yields, floral form and quality through the roof.

The only sensors to buy in my personal opinion are the Apogee Gold sensors, read about them here.

 

TIP 3 – IPM (INTEGRATED PEST MANAGEMENT) PREVENTION IS MUCH CHEAPER!

We all know that growing indoors provides the perfect environment for plants, it also is the perfect environment for pests and pathogens to breed in. So many growers in mid flower come to us with pest problems, the conundrum here is that half of the consumable crop is now developing so spraying pest deterrents is not ideal as excess moisture in the flowering phase can aid in the development of botrytis and other fungal infections.

So what do we do? We go for prevention instead of painstakingly looking for a solution. The moment your precious seeds have germinated or cuttings have rooted, we highly encourage to spray once-twice weekly to prevent the possibility of an attack, by implementing this procedure the plants immune system will strengthen making it near impossible for a potential attack.

Using these pest treatments for the first 4 weeks of growth will set them up to be stronger, healthier and more vigorous.

Once you actually try the AGH IPM regime you will never look back and your plants will perform much better.

All of the IPM foliar sprays included in this tutorial are completely organic and have withholding periods that do not exceed 7 days, and are all approved for use on consumable crops. 

Until next week, grow hard.
