Get rid of the doom dude honest ,once those seedlings have a tap root,just plant them and put a light over them,has soon has there about a cm above soil level I have a fan on them has well it just ossalstes on low - but found it makes them stronger in end.Only time I use dome is with clones and germinating beans.

Generally the plant likes cooler temps at night around 17-20C so about 65-70F. You don't want temps too cold like 12C.

My tent temps are currently around 22-26c during the day and around 17-21c at night(Coming to the end of week 3 veg flipping today or tomorrow :cool:).

I've started putting the heating on for an hour after lights out just to keep the temp/heat threw the night in the actual room(16/8 schedule) where the tent is. I also keep hygrometers in the room and the tent. Keeping an eye on the temps threw the night the lowest I've let em drop is about 15c. Can't really comment on mats/domes never used them.

Humidity is sitting at no more then 55-60% currently. Like I said heat can be lowered by increasing the humidity and humidity can be lowered by increasing heat. However at night when the temps drop(heat from lamps) the humidity will raise(mine about 70%). Due to temp dropping.

25c outside or night temp? Currently where I live. it's fucking freezing at night will warm due to the summer coming.

Edit: My strain is barneys farm critical kush

Once you seeds reach the stage where they have a rail - heat mat on and seeds dropped onto paper towel inside a sealer bags ,I have worked with 500 plant grows per room 3 rooms 1600 to germinate seeds,out of those 1600 seeds they was all good apart from around 8/9 if memory serves me well ,then I do them 1 at a time most of time 100% success rate ,apart from velvet moon ,hard batch to sprout most do OK but some just won't have it .Once uou have a tail around 6/7 mm then plant them tail down straight under lights with a fan in them low they need those stems becoming tougher early on

hope this helps
My temps are far at my led grow 2/3 ,hoping on ditching that last hps this summer wanting a sf6000 from spiderfarmers though

Depending on your light, 12” is potentially too close, especially for seedlings. You mention the ac infinity 3x3 tent. If you’re using their S33 light that fits that tent, 12” is too close. They actually recommend 18” at 40% for seedlings (see below), though I have found that to be too close for some plants and generally operate at @20”, which can still be pushing things in terms of ppfd. Your light may be too close for the seedlings. They’ll take it better when they’re a bit larger and you slowly dial things up. And lose the dome like everyone recommends. I’ve never used one at all.

Heat mat can definitely help with the seedling stage - I used one around the clock for the first two weeks or so on my current grow (I’m still pretty new to this too). Removed it once the roots were really spreading out, as I can not adjust heat in the mat and the soil was actually getting too warm, which could promote unhealthy stuff in the root zone as I understand it (and one of the plants in particular was not enjoying the experience.)

In my current grow, all AC Infinity stuff, 3x3 tent like op, S33 LED, I’ve had the light generally 18-20” from the top of the canopy. I’ve had to turn it down or raise the lights a few times when the plants were showing signs of too much.

Posting a recommended height/power level chart from AC Infinity. This is for the 4x4, but should be similar. Just suggestions, as individual plants will react differently.

So when and what do you do to feed them the 1st time?

Mine were about 12 days old (above ground) and they got their first dose of 1/2 strength nutes. I went 1/2 strength because the Black Gold does have some mild nutes in it. They loved the nutes! I'm trying a new brand of nutes, it's a three part called Bud Doublin. I normally use the Fox Farms trio with Cal-Mag, but wanted to try something new.

Yea 30% at 12 inches seems about the same as 40% at a foot and a half. My seedlings seem to like where its at. I ditched the dome once the seedlings sprouted and the leaves with the serrated edges started growing.

So far i got 2 that seem to be doing ok. I got another 2 in the dome right now that just came up out the dirt. The one had a really hard time geting the shell off but it finally got it off. Not sure how that one will do, as it seemed like a really long tap root with a shell on it. The other was the last one to germinate, i was about to throw it out too, it looked like a dud, took like 4 or 5 days about to show the tap root. She just popped up and looks good so far.

My new problem is the ac infinity t3 humidifier. The stupid tube like drips alot of water and or makes it stop fogging because the water gets cloged up in the tube. Im surprised that such a innovative company used such a shitty idea with that tube.
I could just put the humidifier in my tent but i only have a 3x3 so space is very limited. I wish i could figure out a solution to this issue.

Does anyone else currently have this same problem? If so did you figure out a way to solve it?

What seed bank and strain are you growing?
I've only ever used GHS RQS and barneys farm.
I once knew a grower who put a humidifier at the top of there stairs/landing by the door of the grow room/tent. Don't think they ran into issues. they also put in the actual room for a while too. They also put a 16" oscillating fan about 4-5 feet away from the tent door( slightly open altho I don't like this idea due to pests) that was a 4x4 space.

I recently bought a cheap amazon 2lt humidifier that I spray painted white I have to fill it once a day and cost me 20. It sits at the back of my tent with the setting on lowest pointing away from everything . Also put a extention bar with switches on(outside of tent) so I can turn it on without fumbling to the back of my 80x80x160( if memory serves correct)
I googled ops humidifier and it looks like a strange design tbh. My one water sits in a tank and evaporates threw the top hole. The only thing I can think of is a saucer or tray to catch excess water as the folks on reddit have mentioned

My extention bar comes in handy for controlling my environment easily :) without constantly disturbing the grow space.

Good luck op

Cool, good luck. I was thinking “seedling trouble” meant not everything was perfect. fwiw, I’ve had to back off the recommended heights from ac infinity, though every plant is different.

I'm currently doing two critical kush under the light this is my first run in a couple of years and with this light, so I'm still getting to grips with the lamp etc. How I'm liking it? so far I'm impressed and considering getting a ts1000 next run.

Before this setup(life issues lol) i was using a 4x4 with a 600w dual spec lamp hooked up to a 6 inch rvk fan it yielded around 6oz of 4 plants ghs silver perl. yielded roughly 6-7 oz if I remember.


If I get round to it I'll upload some pics of my setup I. Another thread or something I just need to remove exif data first :)

Lighting needs to be much closer ,especially if they are already in your soil . 6400-6500K gives them useful veg photons...see what 38W LED does to roots of a couple bns in coco peat pucks with RO water...no dome.

Yoo please tell me do you buffer or treat your r/o water? My R/O comes out with a PH of 10 and seems to be unmeasurable ( it swings up and down )
