You can use this as a guide ok should help in what you need.
@Myfriendis410 @Covertgrower @LoCoRock @Noctis420 @imSICKkid @Drinkslinger. So I germinated 5 seeds and all popped! So stoked to see something after all the research and reading I have done. When should I take my humidity dome off? All the seeds have broken the surface all but one I can see the leaves. What are my next steps going to be?

When they donāt fit is my recommendation. Unless you know your tent RH. Itās above 50%.
Other than that donāt over water. @Capt.Cola

I got these koram seed starting trays and I love them. They have a vent on top to open up for air without removing the dome.

Nice that it has a vent @Noctis420. I wasnāt sure with autos if I could transplant. This time I went directly into 5 gal fabric pot. Mine are a little smaller than your but must be close in age.

What height should I have my lights? They are not the good lights you guys have but all I could get at the moment. One is a 600w vivosun that I think is really 180w veg power and 240w full spectrum and the other is a green go from amazon that says 190w nominal power. They are currently around 40" for germination. Should they go down? And should I use just veg for now or veg and bloom

Hey @Capt.Cola Sorry about that. I didnāt remember you were growing autos, thatās my fault. You are correct about not transplanting autos. Itās best not to stunt them in any way possible.
A good way to tell if it needs more light is if it starts to stretch. You can leave the bloom button off for now to save power. I would probably start with your weakest light and put it at 24". Just watch the plant closely once it sprouts. The 600w is going to be really strong for a seedling imo. I used to use Mars hydro 300w LEDs for veg starting out at 24". The 600s are powerful. I only used them for flowering. This is just my opinion and what has worked for me. These little seedlings donāt require a lot of light and you can save some $ on your electric bill. Iām assuming you have LEDs? You could slowly lower it down as it grows. If it grows tight nodes then itās to close and if stretches you know itās to far. There are other signs the plant will give you if itās to close. Just be vigilant. Hope this helps. Happy Growing

No worries @Noctis420 thanks for helping me out. Iām not that familiar as to if the seedling is stretching they just showed themselves this morning but seem like they already grew. Iām only misting the soil and have a plastic cover on them. I will keep an eye on them. Would I keep my lights at the same height even if wattage is different? Thanks again @Noctis420

Youāre welcome @Capt.Cola you should just mist inside the cover and not on the soil. Be sure to lift it up a few times a day to give it fresh air to avoid any fungus. As for wattage the more watts the stronger it is. I read that the vivosun is recommend to be hung at 18" to 24" for flowering. Iām not sure about the height of different watt lights. Iām trying to come up with a good answer for you so Iām doing some research.

Ok so I looked up all the Mars lights that I have. Iām pretty sure all these leds are quite similar. I have these a 300w, 600w and 720w and they all say this.
Recommended Hanging Distance: Seedling: 24"-30", Veg: 18"-24", Flower: 12"-18".
Any chance you have the original Packaging? They usually come with directions. I believe I have all mine but I donāt have access to them at the moment. I think what Iāve found is pretty accurate. Also I love helping so tag me anytime.

@Noctis420 I looked through the vivosun paperwork at least 4-5 times. All I can find is 4x4 at 24" and 3x3 flower coverage at 24". I think Iāll lower them according to the heights you listed and email vivosun in the mean time. Maybe Iāll replace light before next grow!

Sounds like a great idea @Capt.Cola You should consider horticulture lighting group. They really are amazing lights and your electric bill will be much cheaper compared to these purple leds.
Hopefully one day I can get one of the horticulture lighting lights. Bit out of my range even if I upgrade. How are the mars lights @Noctis420. It looks like they are more affordable.

They arenāt bad, but just not very efficient. They did pretty good tho. You can check out my old Journal here Noc's 2018 Grow Journal.
During the summer I had heat problems while using multiple Mars lights. That journal was when I didnāt have any hlg lights. You can get the pre-assembled hlg lights for pretty cheap. I use the hlg 65w ($100) and 100w($150). Iām still waiting to upgrade further.
