How to get a drier climate in the greenhouse

Not long ago we had an excess of moisture in the house. Windows fogged up all the time. The water dripped down sometimes. We wondered what was going on, because of course that wasn’t a very healthy situation. Mold would appear before you knew it. And to open the windows every time, only to have to warm the house again isn’t a very good option either.

Fortunately the cause was found quickly. Research showed that there was a lot of water under the house. And of course you want to get rid of that as soon as possible. The solution was drainage. And we’ve had a pleasant and healthy home environment since.

There's often a similar situation in the greenhouse. I often hear growers talk about a climate that’s too humid, with all the associated risks. The only solution they can think of is to open the windows while continuing to heat to get things dry again, which is actually a huge waste of (expensive) energy.

What I find most peculiar is that we hardly seem to wonder about the cause. If we knew it, we would also be able to come up with a solution. Because for many plants too humid a climate is also very unhealthy. If this were not the case we wouldn’t, after all, invest so much expensive energy in makeing it dry again. The risk of failure is too great.

Personally I find it a challenge to always look for solutions that really put an end to these kinds of problems. I also really enjoy seeing it work and growers being able to focus on growing with more pleasure and higher yields. "Half an hour after watering, this cultivation floor is bone-dry again!" or "With this cultivation floor you can perfectly regulate the climate around the pot."
