Awesome, I figured the seedling will be fine because Cannabis is a very hardy plant and can survive harsh conditions. She was completely tipped over and just laying on the lava rock due to a couple problems when this seedling sprouted, number 1: it was not planted deep enough and part of the root was emerged from surface. So I covered it with moist pieces of Rockwool cube. Number 2: it had no fan on it its whole 5 day life....I now have put a half of a Rockwool cube around it and is propped up and fan is strengthening the stem. I also filled a spare 5 gallon bucket with water and placed a glass water heating rod to help with humidity, as it dropped to 68%. It is now up to 79% and expect it to raise to atleast 80-90%, with temp of 82F. If any one has any tips on how to do this better, please dont hesitate to respond. Thank you for the help!!!

P.S. how do I hit a "Like" button on someones post if I like it?

I dont add a fan until at least 7 days, they do have negative pressure from the circulator though, a toothpick will do fine to prop a seedling up till it can do it on it's own, But it's a fine line that common sense will tell you when it can take it, trial and error my friend, I personally dont worry about humidity with anything but flowering plants, any other time usually the rooms humidity will work fine unless you are in a desert or jungle ( 15-70% ) works fine , flowering is another story, any more then 50% and you may see issues arise , as for likes , the bottom right of the post you should see the number, a like and reply button, :) Damn I miss that rep button :(

Lol, I don't see a like button, I do see the # button and reply. Well do you think a fan should not be incorporated yet? Till the seedling reaches day 7, or a certain height? Cause I have seen them dry out before, but I doubt that with this girl. She has a powerful air pump blasting bottom of bucket creating humidty and a bucket loaded with heated water. Humidity is now 79% and temp is 82F. Thanks Budget Buds!!!

REPLYING TO MY OWN POST:

I just checked on her and she is back in action, standing up and the fan is helping it build strength. How do I start my own new thread, and under what category? Hydroponics?

No sir, do what you think the plant needs, my room will be different from yours unless you live next door to me in northern michigan, I generally let the seedlings get there legs before a fan though, ie a good taproot several inches in length to counteract the force the fan will give it . as for temps. with a dwc you will come into issues with the temp of the nutrient solution's in the bucket, any more then about 70 and you will see slowed growth or root rot ( ask me how i know) eventually , dialing back the light or introducing a chiller or ac is the only way i was able to get it in check, with the less light you will see less yeild. it is a fine fine line getting a room dialed in and to be honest it's why i now run aeroponics ( took me over a year to dial in to a .1 accuracy). Welcome to the game my friend, it's a hobby like anything else and it takes time and effort. you cant like your own posts, only others lol :P

Aeroponics. That is a great method that I have not tried yet, but I would love to try it out some day. Right now Iam fixated on Deep Water Culture. About introducing a fan to the environment, when I did this when I lived in Minnesota, my super lemon haze dried up on like day 2 and I touched it and it broke....While now that I have moved way south, fan should not dry out my baby as humidity is great. Plus, just do what I did, place a bucket full with water and a heating rod in it to produce humidity. Humidity is now at 83% and temp is 82F.

How do I start my own thread? also, I was not trying to like my own posts, I was trying to like yours, and others, lol. I think it might have something to do with being an established member. Thank for the help bud!!!

this is NOT correct.

In a healthy hydro system, the pH should not be "jumping" up each day as you mention. And you most definitely should not have to be adding pH down every day. In fact, you really don't want to have to much pH down in your nutrient solution if possible.

Now, to figure out your problem we need to know a little bit more here:

What type of nutes are you using? What's your ppm?

How far along are your plants?

what type of hydro system did you build?

what is your growing medium? (this is an important question. For example, if you're using rock wool, and running a drip system, then this can cause your pH to rise. The reason it can is because rock wool has a high pH, so dripping through it can cause your nutrient solution's pH to rise).

what type of water are you using (e.g. RO, distilled, tap, etc.)?

This should be a good start. I'll try to keep an eye on this thread and watch for your answers.

PS
I run a DWC hydro system. I use 18 gallon totes, with 12 gallons of nutrient solution. When I mix up a fresh batch of nutes, i of course adjust my pH. This is the ONLY time I need to adjust. In general, it stays right at 5.5 until the next nute change.

which brings me to my other point, someone mentioned a pH of 6.2 for you. That's incorrect as well. That's pH for soil. For hydro you want to stay in the realm of 5.3 to 5.8, no higher no lower...

Coco is a hydro medium and I think oh at 6.2 is better then 5.8 I get bigger yields. You say 5.5 I think that’s too low, between 5.8 and 6.2 for hydro does work
