Experiance with dehumidifyer

Defoliate. Dehumidifyer. Silica gel. Put outside sour exhaust from the room. Less water your plants. Just wait till your grow medium is dry.

Start a diary or give more info. Do what has been said already. Also don't have any water left in like run off or spills. Is it a tent or a room? Are you exhausting the stale air via a fan? If in a tent then the dehumidifier should be placed outside as it's the incoming air that wants to be drier. Another help could be to raise temps to keep your vpd in a good range. Generally speaking the higher the temperature the higher the rh. Also the stage you are in dictates ideal parameters. Seedlings want high rh, like 70-80% In veg 50-65% is ok and in flower you want about 40-55%

can you exhuast the air from the room that contains your plants to the outside? This would help. as you rplants grow larger, they release a lot of moisture into the air. You can defoliate it a bit to mitigate the spike, but you don't want to remove too many, since leaves power all growth and are essential to a happy plant. exhausting outside can help, but if it is a high RH day, it won't do much, obviously. the only way to control it consitently is with a dehumidifier. Go larger than you think you need or else it'll run 24/7. i've go a 50pt dehum (70pt on old standard of measurement), and it can keep up with 10-12 plants in a large room, but that is the limit. When i did more plants it was a fucking nightmare with humidity. That's a 450w device, if i recall. A handful of plants wouldn't need somethign that large, but definitely go a bit larger than what you need. it'll save wear-n-tear on the device if it doesn't have to work as hard all the time. The other Thing to consider -- Is this happening at night when temperature drops? if so, you can keep temps up higher and RH will not spike as badly. RH is relative. as temperature drops, RH rises because cold air cannot hold as much vapor as warm air. The RH is how easily accessible the water is, which is the key for microbial risks. So, if this is only occurring afte rlgihts out, you could stop the temp from dropping and that would stop the spike. this may be more expensive than a dehumidifier. If you don't hit the dewpoint, i'd go with the dehumidifier, imho.

Do not buy cheap and small. Overkill is always better option. Range from 300$ will do good things even to 4 square meters. Smaller will sort 4sure. Should be solid, one time and for all investment.

During the vege season with a good fan there should be no problems.Problems may arise during flowering.A more powerful fan or dehumidifier if you live near the sea

It depends on the size of the growth room. The bigger is the room, bigger is the dehumidifier needs to be.

Hi! A Dehumidifier is definitely worthwhile. Higher humidity provides a nice environment for mold to thrive. Mold can wipe majority of crops out within 12 hours if not culled. Look into Bud-Rot for some sad pictures. During Flower you'll want no more than 55% RH (Relative Humidity). Another thing to watch out for with higher humidity is cooler temperature. Anything under 69F is also hospitable for mold spores in conjunction with high humidity.
