My T5 fixture finally arrived and although it’s a tight fit it works in my partition.
With all four lights on it’s pushing 85 degrees, even with a fan and it unzipped open to the room. I’m thinking two lights should be sufficient.
I dropped two seeds in some distilled water with a splash of hydrogen peroxide and covered it with tin foil. The tails showed up within a day or so. I think I’m going to forgo the paper towels and just put them Dixie cups with Light Warrior soil from here.
10 days from germination and I think things are going well. My first seedling looked like it was stretching so I brought the light closer. Of course, that heated things up so I unzipped more of the tent to the open room. I’m reading a bunch of recommendations on humidity- with ranges of 40 to 80 percent for the seedling stage? It seems to be hanging around 50 so I added a small humidifier to bring it up some. How are things looking? Anything I should be doing differently?
Three weeks out and I’m concerned things are growing too slowly. I’ve added a small humidifier to get the RH around 70%. I wonder if I switched from the t5s to my HLG 260W LEDs - would they grow quicker? Or is this the appropriate growth for AK-47 autos for three weeks? I’m hoping the discoloration on the one leaf is only water burn. I’ve been careful with water, but as they get larger I’m watering a bit more each time. Yesterday was the first time I noticed dripping from the bottom of the cups.
How much are you watering at a time, yes mine were larger than that at 3 weeks, over watering will indeed slow growth, i think your light is sufficient for this stage. Maybe some others will dive in, tag people like this. @Covertgrower @dbrn32 @Skydiver @Oldguy
Normal to have slow growth at this stage. They produce a lot of effort to make leaves, now they’re making more roots. They’ll take off again after they get some established.
The others are correct, but I agree they are a little small if indeed 3 weeks old.
I’ve been using a spray bottle with distilled water daily. Yesterday was the first time I watered to the point where I had drainage out of the bottom holes. Thanks for the links to the others 
- it is appreciated. I transplanted the plant with the spots into a fabric pot and it seems to be doing better. At least the spots don’t seem to be spreading.
Feel free to move them all to larger pots with fresh soil if you want. They will tend to stall a bit expanding roots but will take off soon after.
Fresh soil is a good thing.
You can also dome them to help with humidity using some clear containers or trash from store/take out etc or pop jug even in the bigger pots but they are close to not needing domes anymore. Usually dome them for a couple weeks or so after they pop up.
Here’s a chart for VPD.
When you increased the humidity you probably also saw a drop in temperatures assuming you left tent open like before.
Humidity decrease tends to raise temps and vice versa.
Doesn’t have to be exact just get things as close as you can as they grow. Shouldn’t be too long where you’ll use the green vegetative stage for VPD.
Hope this helps
Thanks a ton @Skydiver ! I did exactly what you recommended and moved all the plants to their 5 gallon pots filled with Happy Frog. I’m a little worried they are maybe a bit small for three weeks out but I really think the nutes in the solo
cups seedling soil were gone (I’m not using anything except
distilled water). Now they are in their final homes. I turned one of HLG 260s to about half power and measured 18 inches away from the plants. I then poured about 8oz of water in each pot in a ring near where the old soil and new soil meet. My local store also suggested using CalMag and Silica but only had the CalMag in stock so I’m at least using that.
Thanks also for sharing the chart - I printed it out and taped it onto the wall next to my tent. I know most recommended against it, but I put a small humidifier directly in the tent to get the RH up and bring down the temp to 80 degrees F.
If HLG260XL, turn all the way down for seedling and veg than start slowly turning a very little at a time neer very end of veg just before flip to flower and by the flip have it about 85% or so they max it out right after the flip. At least that’s the way I do it with my 260xl. Well I do it like my main amps in my audio system crank it wide open and than edge it back a hair.LOL. BTW nice set up
Thanks. Maybe I should turn it down to a quarter strength then. I’ll back it off a little.
If you have the driver with the dimmer bilt in, turn it all the way to the left (that’s 50% power) that’s all you need during seedling and veg so I’ve told!
@Audiofreak Wow, those plants look healthy. I turned my HLG down a bunch and my plants seem to doing fine. I almost wonder if it would be worth buying a light sensor to determine what intensity is actually reaching the flowers. Between the internal dimmer on the driver and the external one who knows what it’s actually putting out? I’m
Probably micromanaging though - I just want to learn. I think my plants are already showing even though they are technically still seedlings? I’m guessing that’s the drawback to autos. Again I just want to keep everything simple at first. I already have my next batch of autos planted - maybe I’ll try some training, even fim’ing, although itscares me to think about.
Gave her a feed today. Ph in 6.6, tds=1014
Runoff, ph=6.6, tds=1243
6th feed on schedual at a bit over 1/2 dose.
I was just zooming in on some photos I took today on my phone and noticed some white spots on my leaves - no buds yet but I still a couple of tiny hairs at the top. Should I increase light or do I have a ways before I can consider it “flowering” I also noticed some bottom leaves withering up/darkening. What I thought were the start of flowers at the nodes turned out to be more branches. I’m definitely new at this.
