My wife and I need to vacation in Colorado for our 39th!
The facility is divided into zones with solenoids, so yup, we water in sections. There's no reason that the crack isn't sealed. The pots we use have feet, so they're not directly on the floor. I wish the floors were heated, but ripping up the concrete wasn't an option.In this pic, 1450757216705.jpg, do you feed all the drip lines at once or use solenoid valves to feed a certain number at a time to make sure pressure is equal. Is there a reason the crack in the concrete isn't sealed, how do you mange cold temps on the concrete in the winter time.
Why would you choose this specific model is it superior to the nanolux/sun system 315s? The specs are very similar.http://sustainablegt.com/ I'd get these for home use... There's a picture of the guts of the ballast somewhere in this thread.

Sunsystems do not have Phillips ballasts, which has shown to not fire the bulbs to their full potential. The ballast is KEY with these bulbs.Why would you choose this specific model is it superior to the nanolux/sun system 315s? The specs are very similar.
I heard that the LEC ran horizontally changed the SPD of the lamp. SGT doesn't state that they use Phillips ballast, but that isn't to say they don't. 11lbs total is a nice weight tho.Sunsystems do not have Phillips ballasts, which has shown to not fire the bulbs to their full potential.

Can you provide documentation that shows why philips ballast works any better for this lamp because I'll be needing to see the differences on paper that it will run this lamp any better, I'm not buying into that until I see it on paper, for all we know all these different brands 315 ballast ar3 made in the swme chinese factory. Do your c philips ballasts carry a sticker or stamp s4ating "made in usa"?
Thanks, im just thinkng the differences will be small, what this ballast has thats special is a low freq square wave digital signal. I suspect little if any difference in specs.I'll check mine once I'm around it.
I purchased Philips because of their amazing reputation for making quality commercial grade products.
Actually assembled in Mexico. What I have heard from multiple manufacturers of 315s is that there are 3 salt packages in the Phillips bulb and the only ballast that fires those correctly in the right temps and order are Phillips ballasts. That being said no one has actually shown me proof either on paper. One thing for sure is you can see them fire over the course of the first couple minutes of start up.Thanks, im just thinkng the differences will be small, what this ballast has thats special is a low freq square wave digital signal.

Was just reading at growershouse the SS LEC does use the philips ballast. Personally I think the chinese have been into electronics longer and harder than Mexico so......Actually assembled in Mexico.

2250 btu cooling takes the light/ballast heat out of the picture.Hello and thank you for posting this fine thread. I have read all the previous posts and hope you wouldn't mind answering a few questions. I have been growing for a very long time and have fallen behind the times on all of the newer products. These 315's interest me and I may want to try one out. If you don't mind I would like to ask about these 315's specifically. I do my grows under a 600 watt in a 4 x 4 tent and get anywhere from 300 to 400 grams depending on strain. Doesn't seem like much but I can live with it. The questions I have are these:
1) Can the 315 match my output of the 600?
2) What would I need to keep my tent cool with the 315? (I'm sure there has to be heat output and I'm wondering just how much there is. I need a very high output fan to cool off my bulb.)
3) How long do the bulbs last in real time working conditions? (Not what the factory says)
Also, I wish I can get my root growth like that. Would you recommend those warrior pots to a soil user? Thanks and good luck!
Thank you both for the replies. My room temps are 78 and my tent stays around 83 - 86 during lights on. So I am about 5 degrees over where I want to be. There is no way to get them any cooler without involving another form of A/C, and this I cannot do.
I wonder what the temps are with the ballast on top of the hood. It has to play a roll in heating up a tent and without some sort of ventilation I bet it will get very hot in there.
2250 btu is a good start. I believe that can be accomplished just by pulling in the cooler air from outside the tent. But db, you didn't post how this can be done, just that it needs a certain # of btu to get it done, or what temps that will achieve.
Fung has good knowledge but doesn't know what the temps are like with the ballast on top of the hood inside a tent.
Sorry for asking about this on your thread merlin. Could people with some knowledge pm me about this stuff instead of replying here? All 3 questions are still open imo
