Hello again,
Well I have put the Northern light x big bud seedlings in the DWC . I have them under a full spectrum ufo 216 watt LED that is about 30 inches away. My rockwool is dry up top and there are roots coming out of the bottom. Ph is 5.8 , EC is 58 and humidity is only at 47%. The plants are nice and green , but I know that I need to get a swamp cooler or something to raise the humidity.
I am growing in a grow box that is 4ft tall 16 inches wide and 9 inches deep.
Any advice would be greatly appreciated.
If the roots are coming out the bottom, then you need to get them into soil or what ever a.s.a.p

I just put them into DWC basin.
I just don’t want to make any mistakes. I know it’s a learning process and I wanted the opinion from some expierenced growers.
Thank you

Thank you.
keep a daily watch on the PH…some will go from 5.8 to 7.2 in 8 hours.

Thank you.
I have noticed that even without feeding them
What makes that happen?
@Newbrn the harder your water is, the more stable you PH will stay.
So if you’re using reverse osmosis water, or water that has very little total dissolved solids (TDS) the ph can swing in a few hours, or a day.

So, is it better to use hard water?

There are some benefits to using hard water. If you often do measurements with a PPM meter, you have to account for the TDS before you add nutrients. If you’re comfortable with doing that, I see no problem with it. @TommyBahama

I have city water and it has a lot of chlorine the ppm is 11.5 so I use distilled water with a ppm of 6.8 and use the ph down to regulate it. I keep my ph between 5.8 and 6.5. My plants are only a week old and look good so far.

@Okie70 this may apply to you as well…
@Newbrn since you have municipal water supply, be sure that you’re allowing your water to off gas the chlorine from the water for at least 24hrs. That way the chlorine isn’t killing off beneficial microbes in your soil or hydro. Couldn’t remember which you were in.
I wouldn’t be surprised if you checked after the 24hrs that the ph has changed because the chlorine is absent.

Welcome and good luck to you and your grow! Just remember…you are doing something new so you are learning. Ask questions! People here are always willing to help. And remember, you may find there are things that work better for you in the long run and it’s maybe a bit different than what others are doing- that’s ok too!
As long as you keep in mind, come time to feed, less is more and don’t get lazy with the PH. Oh! And if you haven’t done so already; there’s this Robert Bergman guy…
that has a grow bible. I find it was very informative! Phew! Good luck and Happy New Year!

am i missing something.???
these numbers don’t seem to add up,
216w LED on one square foot.? is this the advertised wattage.? what is the actual watts used.?
EC is 58.? is that supposed to be 0.58 or 5.8.?
seedlings (plural) in a one sq ft box, how many r u gonna keep.?
the 47% humidity is good, 30-60% is fine,
the struggles of raising the RH is not worth the small increase in growth.!
if your DWC is in the 4’ tall box the res is probably way too small, especially for multiple plants,
when the roots fill the res the pH is gonna swing like crazy,
it your res is less then 4 gallons I’d suggest planting them into some FF or Pro Mix or coco/perlite in the biggest container that will fit in the box.!
u can always go back to hydro when u get more room.!!
