Thanks for the responses guys. I will take pictures without the HPS and update accordingly. I recently calibrated both the PPM meter and the pH meter with store bought solutions, since the swings were so big I was suspicious. The swings would happen overnight - at first I would try adding pHed...

I'm about 4 weeks into flowering my Northern Lights in RDWC (connected 5 gallon buckets) Take a look at the pictures: the bud sites and leaves on the top half of the plant (the older, more grown out stuff) is all healthy and green. But all the new growth tips and bud sites that shot out during...

Hey thanks guys. I'm proud of those roots! I remember seeing pics like that online a few months ago and wondering if I'd ever make it there...

Thanks, and I hear you! One vote for lollipopping.. would you say I should do it right away, or is there an optimal time in the flowering phase? I imagine it would put the plants into shock.

OK thanks for the feedback. The tops have the biggest bud sites on the plant though, would you really have me cut those down 2 weeks into flower? And when you say 'bend twist tie', could you describe that in more detail?

Oh and Nutrients in case anyone was wondering: - General Hydroponics Flora trio - ProTekt silica supplement - Beneficial organisms: Hydroguard, and later bought Great White Note: I started seeing signs of pythium/algae in the buckets. I took a variety of measures over time - water chiller...

Here they are as of today, March 12! As you can see, it's a beautiful hot mess. I stopped LSTing after I ran out of horizontal room, and just sort of let them grow. I read plenty about defoliation and supercropping, but haven't built up the courage to really do it yet. I did a round of minor...

First time grower here! - 5 feminized Northern Lights from Nirvana - Grown in connected 5 gal buckets with another 5 gal bucket reservoir, actively recirculating via pump and top feed lines. - 1100 gph air pump (60w) with a line to a 5" airstone disk in each grow bucket. For the first 6...

Thanks for posting your formula... would you be willing to share your veg formula as well?

Thanks ruwtz, very informative! Have you looked at the cost effectiveness of these formulas vs popular commercial ones? I'm wondering if the low price of the bulk salts would compensate for the variety of ingredients and work that needs to be done (once all the research is complete and the...

This is an awesome source, thanks for the link! For sure, if you're willing to post. Knowledge is power! I know it's a potential rabbits hole... It's just one more area to optimize. But hey, we do it for the love the science/art, right?

So we're all probably familiar with the many charts circulating the internet that shows how nutrient uptake is affected by pH range. We're also all equipped with EC/TDS meters to know the total concentration of nutes in the liquid. But my interest is in how one would determine the 'ideal'...

I thought about just getting a bigger humidifier than the one I had, but if a $40-50 humi doesn't cut the job would a $80 one make enough difference? My problem is that i want to be able to fully ventilate the tent but also keep the RH up - which means I need enough humidification to raise the...

I did! (See original post)... it's just not strong enough. I might have to upgrade to something more intense. So I did try that for a few days - filled a 5 gal bucket with water and left some towels hanging over it with a fan blowing on it - you can see it in the bottom right of my pic. Thing...

Don't think so, I'm in an apt building with central air. But the heat from the grow tent keeps my little 1200 sqft apt quite toasty (hence why I keep the windows open in winter)

I said I'm growing '5 Nirvana Northern Lights'.. in a 6x5gal rig with an extra 5gal reservoir. Exactly. I went with indoor hydro because I'm looking to create ideal conditions. I'm looking to fix bottlenecks and I'm concerned low RH is one. When I say I don't run heat I mean I don't use the...

(Pictured: My tent with the 'alternative' setup, no circulation, vent cooling for light only, and higher RH) Winters in New England can be very dry. Today our apartment (and my grow tent) hit 10% RH! I have a 5'x5'x80" grow tent for a 6 x 5gal RDWC with a 5gal reservoir. 5 Nirvana Northern...
