With a 400W lamp you aren't even on the horizon. The PC you used to post this thread probably burns over 1kW if you include the monitors. A vent from a cooking range probably exhausts more heat. FLIR cant see through walls. It can see hot spots.

Effectively, no. You can make the clones but they are on the same schedule as mom and will die when she does.

I dont know if there is any scientific data for it, but many pro growers and breeders put their plant in the dark for 24-48 hrs before 12/12. Since they do it, I do it too. In fact I have one in the closet now. It's not crucial but it's always good to make any kind of change in the plant's...

Wow. All those 3's must add up to a lot of money if you do the figuring. What a deal!

I think if you are going to make seeds from your plants it does matter. Quite a bit. You can expect a significant percentage of their offspring to be quite unlike the strain you bought. You might like what you get, you might not, but the point is that you can't perpetuate the strain just by...

My understanding is that if you make seeds from your plants they will not breed true. You are starting with an F1 and recessive traits will appear among their offspring.

If she is putting out fresh white hairs she is still making buds. From the video it looks like a week or two. Why not cut a small bud, quick dry and test smoke

Good choice. You will like it. :)

I start mine in 3" pots. If I get to many fems, I put two to a pot when I transplant to a larger container.

Don't worry about the M/F thing. Just do your best for the seeds and they will do their best for you. It's true that no cultivation technique can alter the genetic makeup of an MJ plant, but, as I understand it, it's not clear whether sex in MJ plants is determined solely by genetics...

I've ordered from Attitude and Sannie's and they took about the same time. In general I've recieved packages of all sorts from Europe and while they usually take 2 weeks, they can take six or more sometimes. Once the seed bank puts the package in the mail, they have no control over it. It's...

1. Yes. The seedlings dont need much light at all. 2. What's the LED spectrum? 3. Dunno 4. Depends on the pot volume, the type of soil and the amount of water already in the soil. Keep it moist. Squeezing a piece of soil between your fingers should leave them feeling slightly damp but not wet...

LED grow lights are still a developing technology. From what I have read here, the effective ones are still very expensive. I heard $700 somewhere.

They look good except for the stretch problem. Seedlings tend to reach for the light. If they get too long, they fall over and pinch the thin stem. After that it's downhill. If it were me, the first thing I would do would be to give them some support. Find something like a bamboo stick or...

That's very good advice but it doesn't work for everyone. Some people don't learn well by reading or by reading alone. They learn by actually doing, which means making more mistakes than otherwise, asking some ignorant questions and some important questions too late but that's their style...

Dr GT's G13 is $200 for TWO!! You can get a pack of 10 from Doggiesnuts for only $700. What a savings!

A 150W mh would be very nice. I am currently using one in my veg cab. My experience was that the 150W MH way outperformed the 250W cfl setup I had previously and runs cooler. It does not make sense to compare the lumen ratings of cfls vs HID. Lumens are a measure of light that is useful to...

A MH bulb will work in an HPS ballast, though it would be better if you disabled the ignitor internally. I wouldnt bother switching between hps & mh. The low wattage MH & HPS setups are quite expensive on a dollar per watt basis. You can get a 150W or 250W setup for not much more money...

I was vegging under 250W of cfls (mostly 6500K and a little 2700K). Plants grew nicely with short nodes but very slowly. I switched to a 150hps and the growth took off. They grew more in a week than they had in the previous month, but the node spacing was stretchy. I added two 23W 2700K cfls and...
