Nutes, that's exactly what I want to do - many thanks. Do you get double colas on the mother plant?

War stories about 3rd generation and greater clones - basically, we're talking about using clones to clone clones. What I've not seen addressed is genetic drift specific to cannabis - here's an article where the author states: "I have read up on genetic shift [sic] and I simply believe it...

That's what I think, too, but haven't seen much reliable information on this.

Can anyone offer insight or advice on using clones to propagate successive generations? Specifically, will the quality fade through generations? The purpose: maximize space in a small-scale home growroom. By propagating the next generation with a clone, the previous mother plant can be...

Also, this problem became apparent only a couple of weeks into the grow, so it's been fairly consistent. The fan leaves grew just fine, but then became necrotic after yellowing like this.

That's the only variable that's really changed between last grow and this one. I think rainwater has a pH of about 6.5, distilled is 7.0. Is the tapwater with a pH of 7.8 alkaline enough to lock out some nutes?

See attached photo. These plants were grown with untreated tap water as an experiment. The purpose is to find the right water treatment. Previously, I've had several successful grows using rain water and distilled water. Drought has reduced rainfall, so that's no longer dependable...

Need advice for attic grow room. I'm considering a dual-hose AC unit so that I can grow year-round. Air to be vented from inside house into grow room. Note that I do a lot of lighting with CFLs primarily because of the heat issue. Even during winter, temps can regularly get into the upper 80s...

You have at least another couple of weeks. See my pics of 67-day-old WW here, so both have been flowering for about the same time. That's definitely nute burn - you gave it too much at once. Flush as suggested, but at this point you may want to continue with straight water. On my next watering...

Sorry - I'm new to RIU! I cross-posted linkbacks to this thread in a couple of different areas, so I apologize if I broached forum netiquette. What's the best way to post, since this covers several different topics? I'm not sure how to bump the thread up. That's very valuable information about...

Closet Grow: Day 67 (see pictures for details) ================================= Strain: White Widow (Seedsman) ================================= Lighting: 20 27-watt CFLs under homebuilt reflector 5 weeks under 65K (18/6) 5 weeks under 27K (12/12) ======================== Growing medium...

See this thread from simpsonsampson420: the idea of pruning, without making it to difficult to understand, is to make growth hormones move to specific areas of the plant based on the pruning technique to increase growth on that part of the plant... most pruning techniques stand to force the...

Your soil is definitely the problem; in general, avoid using soil mixes that come pre-mixed with nutes. I also use Fox Farm Ocean Forest exclusively. I agree with the others that you shouldn't feed until at least after the first fan leaves appear if you're using a good soil mix.

Great thread! I'm anxious to see your garden grow. With CFLs, you can use the 65K for veg, then switch bulbs to 27K when you induce flowering to maximize efficiency and generate thicker buds. The downside is that you have to buy two complete sets of CFLs.

As an addendum, please note that humbolt's paranoia about posting on a forum such as this is unfounded. It would be extremely hard. almost impossible - law enforcement would have to match post times with server and ISP records across multiple jurisdictions. The only agencies who could even...
