Hi everyone, I have recently built a 15’x40’ greenhouse which is heated and dehumidified to grow plants this winter for my landscaping company. I will also probably try to grow some auto-flowers in it this winter. I have some lights ordered since I live near Portland Oregon where the winter days...

Well...no response on this one but I did more research and answered my own question. just in case anyone is curious for an answer. It seems like light is equally as limiting as temperature for plant growth during winter months especially in northern latitudes where it is just a small fraction of...

Hmm...my greenhouse stays around 65-75 (18-25c) most of the time but can drop into the mid 50’s (about 13c) on really cold nights here cause I still need to upgrade my heater. Still wondering if it will not grow much due to light levels but wasn’t sure if anyone had tried it. Maybe I just need...

Hi there, I have a climate controlled greenhouse (temp, humidity, co2) that I use to grow plants for our landscape design business. I know photo period strains wouldn’t do well growing in there in the winter without supplemental lighting. What about auto flower strains? Has anyone grown auto...

So I am finally getting around to the cleaning and have done everything but the light, I have led lights that are still under warranty and say opening voids the warranty any ideas how to clean without? Maybe air compressor with trigger nozzle through vents? Also guessing air filter should be...

Hi everyone, up until my last indoor grow I have been pretty lucky to have avoided spider mites. However, I got them on my last grow and got them bad. I have a few questions on moving forward to my next grow. My box has been empty for about a week. How long can they persist in there without...

Some healthy looking plants, my buds look about the same right now, hoping they bulk up a little over the next few weeks, they seem to be putting weight on quick. I didn't think i had enough plastic but i found enough scraps around the house, one of which was big enough to make a solid roof...

I just put the canopy up and the top colas are pretty dark, will they still mature with dim light? Id rather not go buy clear plastic unless i have to, what about hanging my grow light in the canopy and run it from sunrise to sunset?

Thats kind of what i thought but i wasn't sure if it would shade out too much light but also wasnt sure if my basic led grow lights would provide much more than diffused sunlight either.

Hi everyone, i have a plant in my back yard here in portland, or. Its a healthy sizable plant for my first outdoor grow with some nice buds that are probably a couple weeks out still, they are beefing up but still no orange hairs. There is rain in the forecast for about 5 days and i dont want...

It is Obama Kush which is an Indica dominant hybrid. It already has the early stages of flowers on it in the almost 2 weeks since I moved it to a 12/12 schedule. Do you really think moving out to 13 hours (with a little transition time) will kick it back into veg mode? I'm fine with it going...

Hi, I got a plant from a friend that was in sad shape, it was tall and sparse, probably due to lack of sufficient lighting. This is my first time growing marijuana but I have a horticultural background so I have been able to soak up a lot of information pretty quickly. I put it under some more...
