Yeah. You should have a fully budded plant, ready to harvest, by mid october. You can even wait until late october to harvest. When 3/4 of the pistils have turned brown, you might wanna harvest, though i prefer 1/2 of the pistils being brown as it gives you more of a head high as opposed to a...
Your attic has fans that draw out hot air when its gets to a certain temp. The air coming out of your grow room wont be hot anyways. 70-80 degrees if you're doing it right. Attic temps reach up to 100 plus degrees on a hot summer day. If anything, your grow room temp would lower your attic temp...
I dont see why not. Try it? You can get a digital ballasts that make you able to set your wattage. You can also switch from MH to HPS with them.
All ballasts do is regulate the electricity that flows into your bulbs. If you were to try it, nothing bad would happen. A lot of people are scared...
I wish you worded your posts better. I feel like I'm talking to a five year old. the co2 ppm would change from place to place, though i dont think it would rise above 1500 ppm. PH usually goes up when you add nutes. Are you agreeing with me or contradicting me?
I guess if you have no nute burn they're okay. They're really wilted though. Outside the temps are okay because of the CO2 in the air, but inside it's not so good.
Do what you do man.
100w cfl? Or 100w equivalent?
The more important aspect of the matter would be how many Lumens the CFL puts out. 700-800 lumens per sq ft is pretty minimal.
Turn off some of your lights man! That one 250w HPS is FINE. Im surprised your babies werent stressed into hermies! You really need to get those temps down. Let your tap water sit out for a while.
Straight water out the tap may have chlorine in it. Let it sit for a day or so. Yes, you should PH it. You need to change that bulb from 6500 to 2700. Good luck!
Haha. That was... Wow.
Atleast paint your walls white, my man. If you can, get some Mylar to go on the walls.
That CFL: Is it 6500k? How many lumens does it put out?
Your need air circulation, not movement. You need air flowing in at the bottom and out at the top.
What kind of soil...
It's up to you. The hermies may pollinate your females. (You did say you had 2 females, right?) But then again, they dont produce much pollen. Your only problem is you'll have seedy weed... The weed will still be pretty good. You def. wont get as much as you would otherwise.
EDIT: Were your...
Well. You can mix organic compost with your soil, but just like any fertilizer, it will run out over time. You will get the same benefits from both putting compost in your soil and feeding your soil organic teas. Just organic teas are "renewable".
