Stabilizing every single element of your , nutrients , temperature , and Most IMPORTANT your light schedules, , veg at 18/6 or 24 do not do 24 then 18/ 6 then 12 It's gonna stress the plant temperature for your water use a heat mat
@Ensign420,for me I haven't used rock wool but they are both ph neutrul so it should be pretty similar on that note , I put my seeds in water until they sink to the bottom on their own , take them from there put into a paper towel , let tap root pop out of shell , plant into peat moss , with a far led light above it , when I see the plant / shell coming out of the peat moss I then put it into 48 hours of darkness in a sealed plastic bag usually I come back and it's dropped its shell atleast by that point
@GACiNATI, Have any experience with seed germination in rockwool? I don't have peat moss and currently only have rockwool and hydroton as a grow medium. What method do you use to get your seeds to crack open? Do you soak them in water? 48 hours of darkness in what? Paper towels? What are the temps? I've been trying to get rockwool germination dialed in. As of right now, I've been soaking my rockwool cubes in PH'd distilled water for a bit, then I flip the cube upside down, make a shallow hole, drop the dry seed straight in, then pinch the hole close. I use a humidity dome to keep RH high until a cube pops. I'll try to germinate a cube in the dark to see if it helps (maybe wrap it in foil or something). Sorry for all the questions, I'm a complete newbie at this so trying to get this right with the grow mediums that I have.
@DougFresh, Nice! Yea, I'm still learning and you are more than welcome to learn as I do! Just keep in mind that I'm a complete newbie at growing (haven't grown anything in any form prior to this). So take my grows as a very rough guide because I am learning as I go and have yet to make it my first harvest.
As for getting more additives for DWC, less is definitely more. I think I spent way too much on nutrients. But if you are not running a sterile bucket, I highly recommenced getting beneficial bacteria to keep the root rot under control (Hydroguard/Voodoo Juice/etc.). Also I'm learning that CalMag is very important. Also keep PPMs low. Don't make the same mistake as I did (you can check out my first grow attempt to learn from my failures).
You seem to have more experience than I do. Your soil grown ladies are looking great by the way! Best of luck with your first DWC grow buddy! 🖖
@BloodSweatBeers, Aye thanks for the good luck! DWC is challenging, especially being a complete newbie. So I'm trying to be as detailed as possible so I (or anyone else who is trying to grow similarly) can look back as a reference (mistakes and all). I failed on my last run, but I'm hoping to make it to harvest with this one! 🖖
@DougFresh, So I plan on ‘low-stress training’ (LST) this girl so I want more height and spacing between nodes before I start bending branches over and tying them down. Right now she’s just too short for any kind of LST. I’ll also be topping her too but not right now.
Are you making sure you keep you water level at the clay balls until It's got more roots ? You need to slowly lower your water level from that down when your starting a seed in and on top of that you definitely need the water temp to stay almost perfectly stable , with the roots being in water you can't let water go below 60 degrees Fahrenheit, with soil you can go to 55 degrees no issues but DWC to low of temps or to drastic of temperature swings even say 6 degrees at a time over 24 hours or less will stunt or even kill a seedling
Have you thought about growing in coco or soilless medium? I think you'd have better luck, and its similar in terms of the micromanagment. Sorry for your loss🥀
@BloodSweatBeers, Yea, I've considered it. If the next few attempts fail, I may just try coco. But still going to try again with DWC. I've been in contact with Advanced Nutrients' customer support team and after a few emails, I think I'm going to give it another go. If not then I'll probably get a fabric pot and try my luck growing in coco coir.
@BloodSweatBeers, Unfortunately, I lost her to root rot (*plays sad music).. But I'm trying again! Trying to run a sterile res this time to see if I can keep the root rot at bay.
