That occurred to me, but I can't recommend it to someone who has a lot to lose. I'd like to hear from someone who's tried it.I don't see why this wouldn't work. Use the T5's top and bottom (morning and evening) to simulate sunrise and sunset even, he may see some interesting responses such as shortened veg time perhaps.
The question was whether anyone had experimented with this technique, and how the quality and quantity of the product held up.A nice controller to simulate sunrise would surely save electric.I would like to try it myself and eliminate cheesy timers im using now. What was the question?
You mean wake up every 2-1/2 hrs at night to turn the lantern on/off?A really good way to save electricity is using the gas lantern technique.
For veg it's
12 on
2.5 off
1 on
2.5 off
No set the timer to that lighting cycleYou mean wake up every 2-1/2 hrs at night to turn the lantern on/off?
Gotcha! Thanks.No set the timer to that lighting cycle
You don't think he'd sacrifice bud growth by knocking back on the HPS?I don't see why this wouldn't work. Use the T5's top and bottom (morning and evening) to simulate sunrise and sunset even, he may see some interesting responses such as shortened veg time perhaps.
integrated daily photon flux density is integrated daily photon flux density. (meaning you will get less daily PPFD than without switching to T5's) The query can be narrowed with inclusion of spectra, but out of the scope here.Can you save power on an 18-hr grow cycle by cutting the HPS to 12 hrs, and adding 6 hrs of Hi intensity T5s? Maybe 3 hrs at either end of HPS cycle? ........Has anybody tried this? With what results?
Yeah, Im in the cheap hydro part of town, too. This guy is in a really high rate area. I like your other ideas, focusing (Central AK)If you want to save power grow outside or in a greenhouse,flips or vert wont save you.
Not using AC can save some but if your not in the perfect place with conditions for it can cost you more in lost production than you save.
Probably the best way to save is new tech lighting like DE's or CMH,these can cut up to 25% off lighting electrical use.AC is going to cost you period,according to cannabis john even high seer units dont help much in our application as our units tend to run at higher speeds all the time.Chillers will save but you pay BIG up front.
High efficiency dehueys like Quest and super efficient fans like hyperfans use half of the power others do and help some.
Also your electric co. and the way they bill makes the biggest difference,I have tiers which go up with higher use effectively tripling or quadripling my bill,i have a buddy in another state that has no tiers and pays a straight 8cents a KWH(Lots of cheap hydro power)with no tiers,lucky fuck.I even put in a 10kw alternative energy source thinking it would at least keep me in lower tiers,it helps me but is no magic bullet,does cover my household use but im still in higher tiers.
Good luck.
I tend to agree. But I still wonder if adding the spectrum of the T5s might partially compensate somehow, or as someone else implied, there might be some advantage in simulating sunrise and sunset. Neither of these possibilities, in my mind, at least, is going to compensate for the PPFD loss of turning off the HPS for 3 or more hours, least of all for 6 hours.integrated daily photon flux density is integrated daily photon flux density. (meaning you will get less daily PPFD than without switching to T5's) The query can be narrowed with inclusion of spectra, but out of the scope here.
I understand, but since no one's posted who's actually done it, I figured I'd offer my dos centavos.That occurred to me, but I can't recommend it to someone who has a lot to lose. I'd like to hear from someone who's tried it.
I thought you were talking about veg cycle with mention of the 18hr cycle. I think it'll work just fine in veg. I would be very hesitant to knock back a full 6hrs of light like that in flowering though. I would be willing to play with an hour or two at the beginning and end of the daylight phase of the photoperiod though, mimicking outdoors a bit more. But then spectrum may need a little tweaking, using bulbs with more red (whoops, did we just defeat the purpose of using the T5s?) than blue, in order to better mimic sunrise and sunset.You don't think he'd sacrifice bud growth by knocking back on the HPS?
VHO's right? :pI have grown giant clams and hermatypic corals out using T8s
Yeah.... I totally didn't even pay attention to the question was about veg! +1 then, I run stupid low light in veg. Lot of years I vegged with 4-13w compacts. I still finish veg with a single 96w PC.I know that that fluoro lighting will work just fine for vegging.
I understand, but since no one's posted who's actually done it, I figured I'd offer my dos centavos.
So let me put it this way--I can't afford to light during veg with HPS. HPS = supercharging. I've done shop lights (T8s) primarily, and then later on T5s. I have grown giant clams and hermatypic corals out using T8s (@MGRox and the other reefkeepers will understand the significance of that) ONLY.
I know that that fluoro lighting will work just fine for vegging. There is functionally no reason why adding HPS to the mix I use wouldn't work, and vice versa.
