What is your biggest question about growing cannabis?

24/7 means 24/0 7days a week
And safely female means it comes from feminized seeds.. and the only way a plant will germ is if you drastically damaged a plant or put certain chemicals on it

Drekthar Although I currently use RO water, I used my tap water for dwc a couple of grows (All last year and part of this year). My tap water tested at 115PPM, I constantly had what I thought was PH problems which is the reason I switched to RO water. In the end, the problem was I was using very little cal-mag when using tap and 1/3 or half (Matching the ratio of ferts I'm currently using based on feeding charts). Still had the same problem.
I separated the plants, continued feeding as normal on one and increased the CAL MAG to full strength (2ml per litre) and the plants exploded. My point is that I should of been using a higher ratio of CAL MAG when using tap, and the full load when using RO regardless of what you are doing with the nutrients.
Whew....

Follow the basic plans and use the "Trim tabs", its just like a boat for me, you can teach someone the basics but to know how and when to use the trim tabs is all about experience. Same with growing. The how to grow MJ on this site is a awesome start!

Time, dedication, research.

Growing for several years now with go o d results with white widow, vanilla kush and super skunk in both fox farm and coir/perlite using 400watts led, GH floura w/CaMg. My issue is high pH --like 7 plus. First month is fine @6-7 but by early bloom the pH starts up. Leaves start showing small tiny tan dots that increase over 2-3 weeks till the margins are filled. The whole leaf becomes pale tanish with light green veins. This happens when I'm unable to reduce pH to less than 7. Thinking lock out. Have gone to as low as 4.5 in and get 7.3 out, even after sevetal flushes with floura-kleen. Have tried both RO and tap and a blend of both with same results. My tap is 180ppm so I try to stay with RO or Distilled with micro/CaMg. Is there any kind of buffer I can try to help me with high 7 plus out water.

Thanks!! I'll have adequate airflow so not worried about that at all. Just was curious about the humidity since I know it's always 20-35% depending on time of year. I do have a humidifier already. So I'll have it if needed.

Don't buy that. It will just add moisture to the surfaces of the grow room, and adding humidity to such a small area like that is just a recipe for mold and wet electronics.

Not saying this is the one but there are loads of these out there

Tags63 many books, articles and web pages on humidity that tout 65% as a good humidity for veg stage and 50% for flower. My summer humidity runs 50% with a new a/c system and winter around 38% and lower at times. All seem less important than light, temperatures and nutrients within the scope of my own experiences. You won’t want to seal the room as you will need adequate airflow thru the grow space to help plants thrive. Welcome to the forum

[dropinbiking]

Plants will add humidity, lights will lower humidity, see above. Probably not a major issue for you.

Hey All!!

I'm new to the forum. Basically, I've been using cannabis for 45 years, been making my own concentrate & edibles for past 2 yrs. I am now going to grow my own indoors. I pretty much have everything covered but I do have 1 question about humidity. They say 40-55% is where you want to be at but is that written in stone?? I didn't start my project yet, just getting things together. But at the moment my grow closet is 20-25% humidity. Of course it's cool out here in NE US & probably will go up but even in the summer it never goes over 35% since I have a very good air filtration system in my place. I'm also assuming when I insulate & seal the closet's grow area with a reflective 1 inch x 4' x 8' panels & install the lighting, will the humidity increase?? Is humidity of higher levels very important for the growing process?? If it is, What can I do to increase the humidity?? Thanks, Paul Tags

I agree, the ambient temperature of the basement is irrelevant if your tent is in the 70’s.

[dropinbiking]

You're fine. Tent temps are what you're worried about. Don't take them out of the tent for hours at a time.

[kronicking]

Yea those don't look bad for all the problems it sounds like they went through. I guess I could try and do a low humidity grow as I read that it seems with low humidity the plants are just going to uptake water/nutrients quicker to combat the low humidity so I think it should be decent as long as I flush every once in a while to get rid of excess salt. the only thing I am worried about is if the temperatures outside of tent being cold will have an adverse affect or even stall out my autoflowers if I have them in the tent at 71.6F-75.2F and the outside of the tent is 59F-62.3F and I pull them out to water/feed (temp drops to outside of tent temperatures instantly). I can't heat up the basement because it will become hot upstairs if I do so I was wondering if that will be okay?

35% humidity don't bother my girls...
