i was recently told that when its getting cold out, like 50's in the day, that buds will slow or stop growing, i would like to know if this is bullshit or not

I've heard the same thing..from my other gardening experience it usually depends on the zonal climates plants are best suited to grown in, and I've heard most strains of MJ don't grow below about 57 degrees F.

I grow fine is 60 range daytime temps. Night times in the 40s no problems as far as I can tell. PNW so climat is not to cold to early.

Thats late flower temps. Not veg cycle temps.

if any person trys to grow a plant in cold it will undoubtly fail. i dont garden MJ right now but my plants do well once winter hits its good bye. if your talking indoors doesnt matter the plant your heated indoor climate will work fine

some plants take cold temps better than others, I've had plants do "ok" in the 50's. But usually they slow down a bit in anything 55 degrees and under, 50-45 degrees, its not gonna do good at all, and anything less, you're looking at a dead plant(s).

Well here is something true: I once started seedlings far too early, but witnessed growth even with temps reaching just over freezing. I did have them protected with plastic, and they were even germinated in cool temps for conditioning. I suppose it was merely a great example of adaptation.

Also flowered a male at 1 inch tall, yet another awesome example of adaptation, in this case with highly restricted growth room. Had pics up a long while ago.

its true. Same as indoor the perfect growing temp for dope is 75-80 ,if temps stray too far either side of this range plants go into lockdown and stop growing.

I would say yes if the temperature around the plants is actually 50 degrees but that's not necessarily the case and often not true. Day time temperatures are taken in the shade. Relying upon weather services for such means you're relying on temperatures taken in the shade at airports, military bases and other urban centers. In the real world day time temperatures are produced by the sun around the plant. If it says 50 in the shade but the sun is bright on the plant then it's not experiencing just 50 degrees why the temps are probably 70 or 80. Another factor with 2 very different instances in most locals is soil temperature. Soil temperature is just as important as air temperature. The cool damp soil of spring has nothing to really lose. It has no heat stores of significance. It has had to contend with winter where as the fall soil has been heated and dried by the summer sun and continuing fall sun. This I believe is one of the primary reasons aside from hardiness developed over time that allows for say a pepper plant which is very fussy about the cold in the spring to survive several light frosts until the plants cells are destroyed and it turns black. Cool 50 day with clouds will certainly inhibit growth but it depends on what kind of growth I think. The latter stages of a plant denied a fruitful outcome subjected to cool weather accelerates it's celebrated decline. If you're expecting a plant to grow in terms of vegetation with an increasingly limited amount of light then you're asking for the impossible. Remember this a non pollinated plant is on it's death bed. She's not worried about 50 degrees. She can take the cold night time air as well because pretty soon she's going to be in an even colder tomb. This is the end.... da da dahhhh beautiful friend....as Jim once said....be more worried about overnight temps dipping below 28. If the weather man says 32...be ready. You're more than likely no where near your weather station and all the cement and thermal radiation released at night.

cool thanks for the info, one other question i have is, say its in the 50's for a few days, but jumps back up to mid 60's- 70's, plants will then resume their normal growth rate rite
