Yes sir. Its just means relative humidity. The amount of humidity that the air can hold changes based on temperature, so rh is the measurement they use when talking about how humid a space is.

I have only run my HLGs over soil and promix, but the sweet spot for me seems to be 80 to 84 with an rH in the low 60s. I know that doesn't exactly match up with what the VPD charts say are ideal, but it works best for me. If I up my rH much above that I have problems with transpiration and...

Oh for sure, I was more directing that to Rdubz who was asking how we all could tell that more time was required. You seem knowledgeable enough based on your first post and I tend to avoid telling growers with some experience when to harvest. Just trying to give Rdubz some tips. The plants...

I mean, the plant looks kind of small and the buds look a bit wispy, but we don't know the genetics he is working with. To be fair, despite being kind of small, in my opinion it is in a fairly normal state of flower development for being 4 weeks in.

You're only 4 weeks into a process that takes a minimum of 8 weeks, and depending on genetics and grow environment may take 12+. That looks like totally normal development for 4 weeks.

oh yeah, 2 to 3 more weeks. :D

There isn't even a reason to be checking trichomes when there are that many fresh, white pistils showing on the flowers because they are a clear indication that the buds have not reached maturity. On top of that the calyx are still underdeveloped and will probably add at least 20% more weight to...

Nanners. Little bastards. That plant looks stressed. What are you feeding it and at what strength? Any light leaks in your space? You can try to locate as many nanners as you can and very gently pluck them out with tweezers. You have quite a way to go until that is ready to harvest so the...

I'm using jacks right now and there is no way in hell I'm ever going back to bottled nutrients. It doesn't matter whether I can afford to do it or not, I refuse to flush money down the drain.

the pistils do seem fairly mature, but those calyx look like they have a lot of swelling to do, and I'd never chop a plant with 0% amber trichomes. That my preference though.

:roll:

4 is better for a beginner. The sad reality is that many first timers mess up. The plants don't always survive. With 4 plants rather than 1 you have a better chance of having at least 1 or 2 make it through flowering. Plus, as stated previously, a much shorter veg time which means less time that...

Listen to PJ. Those plants are way too small for a 600 watt hps to be that close. You are essentially forcing them to try to transpire and grow at a rate that the root system and amount of foliage present are not ready to deal with.

Some minor adjustments to feed schedule and ppfd and they seem a lot happier. I am not certain if i will keep updating this thread or not as it isn't getting much interest, but here is where they are at as of this morning. Day 2 of 12/12.

I'd check to see what is already in your soil before making up your mind. Silica is used less frequently in soil because many potting soil mixes are already rich in it. That may or may not be the case with what you are using, but it is always critical to know what is in your medium before you...

How are you exhausting air from the grow space?

It also depends on whether you wet trim or dry trim, and how much you break down the plant. A wet trimmed plant broken down into colas and branches will dry faster than a plant hung to dry whole and to be dry trimmed. I hang my plants whole and I dry trim so 60/60 is a no go for me. I've had...

I've found that the ideal humidity to dry in changes based on temperature. I'd happily dry at %54 humidity if my temps were around 65 f, but if 55 f is all you can manage you may want to try and get the rH down a little bit. My formula has always been to keep temps between 62 and 70 with an...

I'll post pics when I get home tonight. :wall:

Anybody else have any thoughts on where I'm fucking up? I'm about to say fuck it and transplant these bitches into some 3 gallon pots with amended soil. I've never had these many issues with watering before.
