a nearby thread starts out with the OP posting some: https://www.rollitup.org/indoor-growing/502572-official-cmh-thread-post-your.html Definitely considering this as one of my tents is just sitting dark.....

It is my understanding that it is the gas (from whence the plasma is generated) that leaks out, not the phosphor coating, anyone want to weigh in on this? which gave me this idea: anyone thought of writing one of the manufacturer's of the bulbs and asking what kind of product might be...

With all due respect, this is the kind of statement that makes PAR growers look bad. Yellow is not useless light, green is not useless light. Red wavelengths are severely over-rated by ganj growers because they mistakenly think the PAR graph applies to plants exclusively. (it is a combined...

A unit that lacks intensity can be maximized by reducing the distance. My impression is that you are still trying to confirm a 660nm effect, the 90 day money back makes this a risk free so I was just pitching that Someone out there should try it Sometime. Honestly you should just solder your own...

4 watters (the unit not the diodes) = harmless they are worried about skin damage from my understanding

There are some light therapy lights with weaker LEDs (you could put them closer, less rearranging?) on amazon for around $40, I talked to the company and the guy says they do a 90 day return full refund no questions so it seems like someone should try this some day. I think it was 660nm but Ive...

Hey guys, I'm thrilled to see this (props Canndo) I was just pondering whether anyone has tried this whilst using medium inoc'd with PGR-secreting bacteria? Unless it's a situation of pressure for the limited resources seems like it would have potential...thoughts? Thanks for your time, MPP

I have a box that blown ones go in, like I mentioned in an earlier post, anything that still radiates light is used to grow veggies. When the box eventually fills (I have CFLs from my house that occasionally go too) I'll go dump it all at haz disposal, flat fee for volume so might as well save...

Tight UC. I found some stuff that has me looking at infrared supplement, was looking at an SPD for a heat lamp and found this nice quote, but let me set it up first: In case you were ever wondering if you could get a girl hot using a heat lamp, remember that "IR-C is already absorbed in the...

when you change the bulb, do you grab the cap or the glass? edit: before ya jump on me for blaming the recipient of a defective product, a scenario I've lived out time and again in other realms, it could totally be the result of shipping&handling too, making the unit unstable enough to reduce...

It is my understanding that the quoted life would be if you had the bulb in a VHO fixture, which is basically an overdriven t5 setup with improved ballasts etc, and so the VHO bulbs also have improved electrodes the takeaway: VHO bulbs should outlast normal bulbs in an HO fixture, so definitely...

Welcome back bro, sounds like you're gonna be swimmin' in killer smoke in no time.

do they still stock cali kush connec seeds @ JC3? If so anyone got any idea what? Just nice to get somewhere and know exactly what you want etc ya know? thanks, mpp

I only say mountain strains because that is what I and others have tested. Many sativa doms that have been bred for the last 30 years under HPS have shown adverse reactions to UVb levels easily tolerated by Kush/afghanica strains. My personal opinion, take it or leave it. I know tropical...

Grave mistakes can be made overlooking the involvement in genetics and UVb response mechanisms. Choose mountain strains for best results imho. mpp

Thanks Kindly! Just got some nice mountain strain seeds and I may wait for the UV t5s to show to sprout em :) MPP edit: That is kinda a sweet graph too, at least, if you were coming in thinking you were ONLY getting UVb...just nice to see the ~440 blue peak

I was just askin about the roseate, seen it anywhere cheaper than dr'sfoster&smith? I'm just lookin for 2footers but I'll report back on the effectiveness. Again im currently runnin 6500K/Coralwave/6500K/CW (2x) was thinking of switching out a bulb for the roseate but I have 2 single fixtures...

Honestly given the difficulties, I wouldn't be opposed to LED supplementation at this point, I feel like I've seen strip LEDs that do high 600's nm. Concerning t5s... I dunno, anyone looked at this before? AquaticLife T5 HO Pink...

Check this, friend: Take a test plant, and two 26w CFLs, one at the exact same height, equal distance from each other---maybe start with 4" just for kicks, at a height slightly above the top of the plant. After two weeks or adequate time for the plant to grow so the top is in between the bulbs...

Yo undercover- you asked a ways back about comparing bulbs w similar outputs/spds. This is actually a huge issue the way I understand (from the pdf I posted like 40 pages back--one of my first on the thread) as there is no known meter which can reliably compare an artificial emitter (light bulb...
