Grow room too cold?

I got about 6 bubblicious in a rubbermaid veg chamber and I noticed slow growth from the sproutlings. Is there a minimum temp that seedlings should be under?

Need more grow info in case that is not the case.....
Need more information about your grow....... cold temps will stunt seedlings though.. you want to keep a 75 80F temp for seedlings no lower no hotter.....

hey,
IME under 60-65 range you may get some stunting for seedlings,
keep it above 70 and you'll be fine, a heatmat under the little ones will do the trick if you don't have a spare heater.
peace

Since he is in hydro seedlings in warm water does not mix; so I would not use a heating pad; normally you are supossed to wait till they get a certain height before you put them into a hydrosetup; seedlings need a certain temp and with you put them in a hydro setup..water temps must be kept around 65 to 70 F 68 is optimal. Sounds like you have a recircu DWC or DWC setup?

if so water temps need to be a certain temp and keeping water temps warm causes bacteria growth; so don't use a heater mat with that.

I would put them in rockwool or rapid rooter plugs and have them root those and let them get a few sets of leaved like 2 before putting them into that setup; this way you avoid this problem that may be the possible cause of your issue......
You got pics of your problem plants?

lol fraken; thanks bro you are a very nice person and your comments are very nice!!
I would love to become a forum mod; but that is up to the admins; maybe someday :)
hehe, I try my best to help out; I can't solve everything though; I am still learning stuff myself. I am hoping this year to get out to the cannabis cup; if not the next year I am defiantly going :)

I just bought a digital thermometer and I'm seeing temps of about 68f which is terrible, I've moved the seedlings into a computer chasis with two fluorescent lights, hopefully things will improve and the seedlings haven't been stunted; I'll be sure to posts updates
