Cold Temperatures Could Be Seriously Affecting Your Yield

Listen up UK growers, this current snap of freezing cold weather could be seriously damaging the potential yield of your crop/plants.

Most of you know that hot temperatures are not good for your plants. What some of us forget is that COLD temperatures can be equally damaging, or in some cases more, than the excessively hot temperatures we all worry about in summer.

When a plant is exposed to temperatures below 17 degrees the plant can go into shutdown mode, protecting itself from dying. Once it’s done this it can take 2-5 days of perfect conditions to pull itself out of what I refer to as a “lock out”.

If your plants are being subjected to cold temperatures then every time your lights turn off I guarantee this is going to have a NEGATIVE affect on your YIELD.

So what can you do to prevent this?

  1. Know the minimum and maximum temperatures in your grow room, pick up a hygrometer if you don’t already have one.
  2. Turn any intake fans off when your lights go off.
  3. Ensure that you have some form of heat to come on when your lights go off.
  4. Thermostatically controlled fan speed controllers are great – they will dim/slow down the speed of your fan as the temperatures in your grow area drop.

Hope this has been helpful, please feel free to ask any questions you may have below.
