Nice line up looking forward to the show!!
I already know that Orange cream is fantastic. Interested to see how the GMO works, been thinking about some crosses of her but flowering time is just too long for me!!
Don't talk to me about trips to the hardware store. You sit in traffic to get a bag of nails, you get home and you don't have a hammer!!
This is a vented room right, not sealed?
Those huge containers of organic soil will provide all the CO2 the plants need. You could seal up the whole show and not bring in any outside air. That should solve any issues of low temps, although I have never grown in a sub zero location so not speaking from experience!
Have you ever measured CO2 levels?
Sorry to hear about the mites again. That's why I'm done taking clones from elsewhere.
Could you turn off the hps and get a pic next week of the garden? I don't know how good your flash is or if you have maybe a regular lamp to put in there for photos.
