If you don't understand the question....well, you might have the wrong hobby. Sorry but I am done being nice about basic biology. Horace Marchner...read his book...standard college biology book
while I'm sure I'm brutalizing the concept and proper terminology-Are the gavitas doing so well cause they're double ended or do they have the highest lumen or is it something else.
Probably gonna try a room with them, So you have to use light movers (up and down?) How high do you want them and how many could a 5 ton HVAC cool?
maybe. definitely run it low. 1.2 ec is my top ec unless shes begging for more but be conservative and only run higher when shes needing it.I too am a Jack's user, but i use tap water. Where i am it doesnt even register on my blue lab. I was wondering if even the Jacks+CalNit might be too much N. 5-12-26 with the CalNit at 15-0-0
i dont go above 1.0 ec in veg and 1.2 MAX in flower, but mainly a solid 1.0 EC all the way through for the most part
Just running into something similar to what Third Coast is.....things seemed stalled although they are starting to fill out more now. Might be just worrying about nothing, but we shall see when all is said n done.
This was the start of week 6....just going from memory I could have sworn they were larger the last 2 runs but my memory could be mistaken

Double trellis. Then support. Then get some more.does the GG#4 need trellising outside? she an early october girl? anybody put her out in michigan yet?
while I'm sure I'm brutalizing the concept and proper terminology-
lumens refers to light that is visible to the human eye, it isn't completely relevant in gardening as plants use PAR(plant active radiation)
you really have to look into how DE lamps work. they are powered from either side of the bulb, there are less internal components inside of the bulb that get in the way of the light, the PAR wattage is much higher and the umol is noticeably more than a normal hortilux/digi ballast combo
also true gavita lighting tech runs the bulb @ 400volts
gavita/DE bulbs carry 95% bulb efficiency through their lifespan(2-3YEARS) so you will save the on the cost of about 6-9 bulb changes over that period of time.
DE is capable of providing a larger canopy area with ideal lighting conditions which lends itself to an increase in yield as well.
there are plenty of threads about DE lighting in the designs & equipment forum, a lot of them have data tables that show PAR readings of various lamp/ballast combinations etc. and things like that that I would highly suggest reading into if you are at all considering making the switch to DE. I'm not trying to sell anyone on em, just sharing what little bit of info I've picked up since I've been researching/preparing to switch my own garden.
here's a safe question to ask: anyone with experience please chime in!
Would anyone that is currently running Gavita or similar lighting purchase standard HPS lighting for an upcoming build?(assuming that height restrictions etc. are not a factor)
sorry to continue the de-rail here, the gavita thread is here https://www.icmag.com/ic/showthread.php?t=228976&page=41Ive only had 2 runs with my new gavita's but I will say that after using them, they cover close to 6x6 canopy if spaced 3-4ft from canopy which is recommended by Gavita. I had originally spaced them out as 5x5, and found that they can pretty much cover 6x6 and with the price of electric I see no reason not to do 6x6 with them.
I have 8ft ceilings which is not ideal but it still works- I just have to keep my plants low and bushy and scrog them nicely. You don't want your canopy any closer than 3ft to the light if your planning on running them on 1000 or 1150w settings.
If you wanted to do a proper commercial grow and have a flowering canopy of 12' x 60' you would need 45,000W of Standard HPS setups (if doing 4x4 spacing). In the same grow space you could get away with only using 20,000W of Gavita's or 20 lights (If using 6x6 spacing). Not only do they cover a lot more space but say goodbye to changing your bulbs out all the time.

what's your average canopy height? are you running standard gavita complete fixtures?
I've got 7'6" ceilings on my current build and want to run gavitas but lean towards the remote setups to maximize headroom. although the gavita remote ballast are currently unavailable due to some regulation that requires the remote setup to be sold as a kit including the ballast lamp cord and reflector in order to have a lamp cord that meets spec. Wazzup recommended that I look into the 750w or possibly 600w setups with my limited head room which I'm cool with so long as I can maintain current yield minimums.
I got 8.5 ft. Hope to pull it off. The real trick Deez is veg
If u can veg with hid its much easier to keep them low and bushy before flowering but get the mass required to get the yield your after. I may ditch my tables for a raised platform on a slant that all drains to a basin on edge with an installed pump with float switch to move runoff
Frame ,plywood on top ,pond liner over that all sloped to one side, drains to pond liner basin to be pumped out. I have a load of pond liners sitting around. Figure that's easiest for me to maintain drainage but only be 6"-8" off cement. Get at least a ft back from my current tables.
I was able to keep 3ft from hood last run but I didn't transplant them up like I should have so stretch was very limited but now I'm confident I can maintain those distances with training or modding my room.
Ive got the 6/750 FLEX series gavita and its currently running maxed at 825w. I too have same size ceilings and im pretty damn happy with how things are going. After the GG4s were done stretching i had about 34" from canopy to bulb.....this is with a 5x5 footprint
