You have about six and a half weeks already and almost five more weeks til the 15th of Jan. That gives you about eleven and a half weeks total or about 80 days. I think you'll do ok if you leave them to the last day possible. They may even finish sooner. What's the stated time to harvest...
The more surface area you have exposed to the air, the faster it will degrade. Same reason fresh ground coffee always tastes better than pre-ground coffee.
The house will obscure the heat signal from above and heat going into the walls will go into ground and be undetectable as well. The only thing you should need to do is cover any windows you have that let daylight in. Just a piece of plywood cut to fit would be sufficient. Even if they detect...
If the main flower is still growing after one and a half weeks I think you're fine. The plant may be sending signals to the other flowers to act like top flowers because of the damage. You might actually have increased your yield!
I would probably just let them fight it out from here on. I am on my first indoor grow, so don't take anything I say for gospel, but I think it's worth letting them go just to see what happens. It looks like you have potential for a good quantity of smoke with what you have as it is.
I really...
The idea of a bloom booster is that the plant doesn't need as much nitrogen once it starts blooming because it has stopped most of its vegetative growth, so the nitrogen number is lower than a veg fertilizer. The high phosphorus number is to support blooming...supposedly plants need more...
What do you mean by red light? If you mean something in the 2700k range, many, if not most, growers use only 2700k light during the entire flowering period. Others believe that having some blue light (6500k range) along with the red is better.
I think everyone will agree that it's best to...
I think a heater in the tent is ok as long as you have good air circulation and it doesn't develop hot spots. If you can keep the temp about 70 or so you should do great.
If the plants are sativa dominant they won't have colas as dense as indica dominant strains. Other than the apparent loose structure, they look fine to me and I'd be happy to smoke some and evaluate it for you when you harvest.
And remember, the final test is how it smokes, not how it looks...
If your basement has windows you might want to cover and insulate them. It could be as simple as bubble wrap and a piece of cardboard taped over it. That is about the only type of hot spot you could produce, and then your basement would have to be warmer than they would expect to draw their...
Davie, the autos will grow for a certain amount of time and then flower, regardless of the day length they are experiencing. Having the lights on longer will give the plants more energy to grow, thus increasing your crop.
