Not sure what you mean by PH lock? biggest part of yield is the machine, build big root systemsquick question color temp versus ph lock in importance to yield what is usually the basic mistakes briefly since the root ball and canopy are both related and important
The PH thing varies with grow style and medium, and yeppers it matters but does have a window or a range IMO it's not the most important thing to be concerned with. If using CFL's use a mixed spectrummaybe block not lock...lol. I mean soil ph getting out of parameters for the most useful intake of nutes. I guess just watering with unknown ph water into unknown ph soil.how that compares to using only one color temp light in your grow for example only soft white cfl 2700K......Sorry just trying to get my best yield.....so many things to watch.....good thread though
I use,,,,,
Jack's Citrus FeED 20-10-20 has 4.9% sulfur
Jack's Aquagold Finisher 7-15-30 has 9% sulfur
Gypsum for Cal, it is Calcium Sulfate 18% sulfur
Epsom for Mag it is Magnesium Sulfate 13% sulfur
When using jacks do you feed the same amount or increase weekly or bi weekly? Im new to growing and dont really want to invest in a ppm meter, but I always seem to burn the tips of my plants anytime I add a little more nutrients. I dont want to push my plants too hard but I dont wanna take it easy on me n get some gussies out of it

Because I researched and digested this shit until I was blue in the face 15 years ago and I aint gonna bother any mo, hah! Gawd, if I had a nickel for every lighting thread 4, 8, 12, 15 years ago.Folks are always amazed at what I do with lights but don't seem to want to learn why?
Why ironic? I'm not saying T5 is better than HPS, never have each has a use and IMO those using HPS could get better results if they added some T5 (or LED) supplementation and by better results I'm talking quality as in potency. I'm fully aware that HPS gives higher yields. And tis very true that many advances in design improvements have occurred since that book was written. But it is also very true that adding deep blue increases trics and resin growthI guess Phillips has it all wrong then, designing those inefficient HID lights for horticulture purposes while their T5s are actually better grow lights.
If you would have claimed T5 can measure up to HPS in terms of yield... but this talk of T5 being better than HPS is getting old fast... speaking of old, that table is based on 30-year old data.
Also ironic how you link that popular article from Gavita.
Well you're kind of implying it here by referencing that table:I'm not saying T5 is better than HPS, never have
and providing other links to help people interpret that.and you will see that Flouros and Metal Halides beat HPS pretty bad
I guess you meant no better T5 then...I use aquarium T5's and there is no better light
Because a gavita isn't just any HPS setup and a good example of HPS>T5. Reminds me of LED fans making comparisons to HPS, they take the numbers of some average old knockoff HPS instead of a real philips in gavita gear skewing the numbers up to 30%.Why ironic?
Maybe it just looks like that because of the smaller buds, ever thought of that? You get the same amount of trics, but on less swollen bud, making it look more frosty. There's only so much blue you need to fill a closet with frosty buds. I grow for resin too... with hps:But it is also very true that adding deep blue increases trics and resin growth
That's the general consensus in the dutch grow forums as well, they call it micro/fluo grows. Although we probably have a slightly different interpretation of what a small garden is.IMO T5's are better for a small hobby grower with a small garden.
Yeah I got that, and a little ironic if you indeed claimed T5>HPS because that gavita article is written for the same purpose, to be able to better judge lights, i.e. be able to see why gavita hps is (on paper anyway) better.But the main purpose of that post was to help new growers better understand that Lumens are not the proper way to judge a light
That actually sounds pretty good. I run 600watt on 4x4 and would like a little more light on the edges. 600watt, especially in my gavita tripplestar hood, is better suited for 3.5x3.5 or 3x4. I've considered LED, CFLs, and CMH (210w version) but not T5 yet... probably going to rebuild and reshape my closet but interesting option to consider especially with T5 with such a reach.If I was growing for yield I would get a 4 foot hood with an HPS and put it in the middle of my booth with the T5's on each side which would give the best of both worlds IMO and I would have the UV & deep blue bulbs in the T5 fixtures as the HPS would supply the reds.
Have you ever checked out Lumi's Illumination chamber at that other site I try not to mention, he used T5's as side lightingThat's the general consensus in the dutch grow forums as well, they call it micro grows. Although we probably have a slightly different interpretation of what a small garden is.
