Heating pad for solo cup

[fatbuds420]

My temps are kinda cold, around 21 celcious, if I put a small heating pad under my solo cup, would that hurt?

Nope I had to do it they will love it roots will explode. You have to water a littler more cuz they will dry out little faster but thats a good thing right?

I believe they are designed for Seedlings

I use this

VIVOHOME 68-108°F Temperature Digital LED Heat Mat Thermostat Controller for Seed Germination

is 21c too cold for seedlings tho?

Temperature: Overall, cannabis seeds germinate in temperatures from 70°F–90°F (21°C–32°C) and grow best at 78°F (26°C). Temperatures below 70°F (21°C) and above 90°F (32°C) impair germination. Low temperatures delay germination.

Def get a seedling heat mat and probably not something you would use on your back. Also get one of those thermostats posted above. that combo works very well.

I use an incandescent light placed about 12"s below a light plywood table, adjust bulb or distance (100, 60 or 40 watt) for proper temps.
My alternative is a 100 mile round trip to find out that this small city don't have one either, so next trip would be 500 mile round trip.. ordering online is not an option for me.

@fatbuds420 just starting your seedlings in there or you finishing the grow in solo cups?

Lots of good advice so far!

It looks like you have the heating pad and the controller, so you're pretty much good to go. And you are correct, of all the factors to consider, temperature is one of the most critical.

​

• The ideal temperature is between 22°C and 25°C (71°F – 77°F)​

• Your growing environment should be damp/moist, but never wet​

• Relative humidity range should be between 70% and 90%​

• Seeds favour fluorescent lighting (Cool White code 33)​

• Minimise the amount of seed handling you do​

• In hydroponic/rockwool plugs, the ideal PH value is 5.8–6.2​

Anyway, give these a quick read when you can - it's from one of our sponsors here:

21 isnt that bad.my toom is between 18-21 in the winter because its A shitty shed . I find cuttings root between 21-23 degrees anyways so it should be ok

The heathing pad I got is locked at 40C 45C ish. I know that's kind hot, but the top ain't gonna be so hot, can I use it for the first week?

I'm kinda desperate, my first gro went amazing and I pulled 350g from one girl


ALL OTHERS I FUCKED UP IDK Why! Second grow I overwatered
Third too
Fourth had to kill them near flower because of popò at my house
And the last one, my Seedling died for some reason in the solo cup. Still not sure why

I literally have ptsd to overwatered my girls. Can I water solo cups by weight?

 

[Vanisle420]

Overwatering is a killer. I have over heared with a heat pad trying to clone with no controller. Controller would be ideal

 

[fatbuds420]

I'm gonna give indoors one last shot, if it doesn't got right, I'll never grow indoors anymore. Outdoors is so much easier

 

[Vanisle420]

I have the opposite problem. I can never get outdoor to finish properly. Just under 2ater if anything and make sure plants are in a comfortable environment

MY first ever grow was outdoors, 350grams one plant. Absolutely no idea what I was doing. Just gave it water and fertilizer. I was using like the shittiest backyard soil. The harder I try. The worse it gets wtf

Do u think 40c or 35c is too high? (the cup half way up is only 26c)

 

[fatbuds420]

Anybody can tell me if it's OK to water by weight on solo cup, if so, how many grams of water should I add each watering? And how much should I let it dry?
