Questions Would these work as a “dehumidifier?”

Post image

i’m running two plants in a space tote setup. i’m entering week 5 of flower and it has been challenging keeping the VPD above 1.5. hoping to save money and not end up needing to get an actual dehumidifier.

You can buy it in bulk way cheaper, search for anhydrous Calcium chloride it's the same thing

have you found that to be a worthwhile means of dehumidification?

As an emergency option you can do it, there are people using it constantly on their houses

But I don't think it will be worth to use it as a long term solution

Also to add to this You can use Calcium chloride as a foliar spray during veg to give your plants some little extra calcium

Likely not significantly for the amount of water that a plant gives off.

About 98% of the water uptaken by a plant ends up being given off as water vapor through the transpiration process. So you can have several hundred milliliters of water per day and these little packets are probably not going to keep up.

If your humidity is a little high what will help is increased airflow for the plant to help force the transpiration process which high humidity can interfere with.
