humidity

[finders]

My buds are starting to grow but I am not sure what level of humidity they should have.
Any help would be useful because this is the first girl I have grown.
Thanks in advance

Ideally (and what's ideal?) humidity should come down through the entire grow cycle and be adjusted for the current temperature. Google "cannabis VPD" if you're in to the complexities otherwise maybe 50% at the start of flowering down to 35% at the end.

Thank you 90Gizmo. This tells me that my humidity levels are too high. I will need to find a way to bring them down.

You can bring down humidity 2 main ways. Ventilate with air from outside your grow area that has lower humidity or use a dehumidifier in your lung room or pre-chamber or even in your grow room. Dehumidifiers do add heat although not much. A desiccant dehumidifier will not work you'll need one with a compressor.
Other ways to reduce humidity is with an air conditioner and also by adding heat.
Edit. What size do you need?
A loose rule of thumb is if you are watering a gallon per day you need a dehumidifier that will exceed that. Personally I have a 13gal/day dehumidifier and was watering almost 5 gal/day and it worked well in a partially sealed grow room with an AC controlling temps and also lowering humidity a bit as well.

Hi finders In addition to what Bluey is saying check out the link. If you haven't already check out the GWE site. Nebula and Sirius have a knowledge data base second to none. You will be hard pressed to find a more comprehensive web site for home cannabis growers than growweedeasy.com.

You guys are great, really helpful. I can't thank you enough. I have just ordered a dehumidifier (compress type) which can be set from 30% to 80%. so that should help. Also, I notice Bluey that you are watering a hell of a lot more than I have been doing. Perhaps that is why my bloom is going so slowly..

My fertigation (watering with nutes in it) was for 4 large plants in 50 litre pots in 100% coco medium. It was a tad more than required if they were all fit and healthy, but they weren't. Got just under 4lb from that grow. Don't change anything with your grow based on how I grow. It was only my second indoor grow and I'm making plenty of fuck ups but learning fast.

Thanks,Bluey. I understand. I was watering too little and I still don't know how often I should water with the nutes or just water?

[Bluey]

Are you growing in coco or something else?

A mixture of soil, peat-free compost and perlite

I'm not an indoor soil guy...the soil I used to use outdoors didn't need nutes added to it and watered twice a week was fine.
How you manage your grow in your soil will be different to other types of soils and grows.
