Yeah I'm really hoping for explosive growth! Everything is in place for it. I have 6 Golden Tiger fem freebies and I'm ordering another pack of them to run next. I'll probably order a few others from their catalog at the same time.

I have noticed the co2 level raise when I have been in the room.
Maybe the Co2 sniffer is in the wrong place?

I have it where Agrowtek suggested and the air flow is great, so I'm not sure why it remains pegged. I shut off the valve to the tank to see if that makes a difference, but so far it hasn't. It would normally go up whenever I went in the room and stay there for a bit, but now it is just staying at 2,000.

Got the second fogger hooked up and I'm holding at 80% RH! Ambient temperature is right at 79 degrees. The CO2 reading has finally started to drop, though it is still high at 1,840 PPM. Still not sure I believe that number, but I'm hoping to borrow another sensor to check mine. The foggers run almost all of the time to keep the RH high. I'm sure it will be a bit different when big plants are in the room.

Something isn't right with your Co2 then. It shouldn't be that high all the time.
Is it still at 2k when the lights are off?
Does your controller have a hi/low 24 hour recall?

It has data logging and trend screen. The CO2 went up about the time I turned on the big lights. Before that I had just the blue LEDs on and it was responding normally. I haven't tried turning off the lights yet. I'll try it and see.

Well I got the CO2 issue figured out. Had a slight leak and it really was that high. It just took a long time to come back down (I had it shut off at the tank the whole time). I bumped the light to 500 μmoles and the CO2 is set at 1,000 PPM. Room temperature is 80 degrees and the leaf temperature is about 76 degrees. The water temp in DWC is 66, the pH is 6.20, and the RH in the room is at 60%. I'm trying to push it up, but those foggers are running flat out most of the time. May have to upgrade to the full size fogger.
I'm hoping to get these girls acclimated to high light levels right out of the gate. So far they are liking it. I'm only going to give them a few hours like that and then back it down to 350 μmoles. Within a short time I'd like to have them under full light. I'm just not sure how hard to push things.

What fogger are you using?... Sorry if I missed it.
I might have to upgrade my fogger as well, as 1 Ultra-Mist doesn't get it high enough all the time.

I see a little burning at the tips. A little patience with wanting to push too much light from the gate. Also one thing to keep in mind with those foggers is that you have a lot of electrical equipment in there that will not work so good once you get everything wet by having TOO much fog. I know it's gotta be a rush to finally get your Starship off the ground, but I would suggest easing into things with new plants, new system, new method of growing before you hit the warp drive lever. Wishing you nothing but the best on this.

Don, do you think the tip burn is too much light or nutes? Thanks for the advice. I'll try to refrain from using the warp drive for now!

Too small to tell at this point. Maybe a too much of both? Hard to say. I believe in treating the babies with a softer hand until they get acclimated. I have an even stronger belief that an ounce of prevention is worth a pound of cure. So with an untested system while keeping in mind the obvious financial investment so far, I think that breaking it in at a gradual increase so that you can document the progress in greater detail to have a system performance baseline would be worth more than you can realize. With that data, were any problems to arise in your grow, you would be able to backtrack, analyze, diagnose, and repair just about anything. Look at how many people with sick or dying crops that log in to ask for help? Not that I am knocking them because I always can respect someone that can put their ego aside and admit they need help. But because I would bet that most do not have that data on hand. Not a fault, just an observation. I like your method of alternating light intensity. Very smart thinking.

Hey ken! Here's the model I have. Their bigger one puts out about twice as much. I never thought I'd need more!

Thanks again Don. I appreciate your words of caution. I'm going to continue to alternate high light levels with lower levels to foster an adaption to high light levels without stressing them. I looked very closely at the seedlings this morning and I believe what you are seeing as tip burn is actually pieces of the seed that stayed stuck to the seedling. Here's better picture to see if you guys can confirm what I just said. In any case you make a good point regarding prevention. I'm insanely paranoid now that plants are going, but I feel compelled to push things to the limit. I need to keep that shit in check and not kill these girls!

The girls looked a little lighter color green than they did yesterday, so I snapped a few pics. How do they look?

Just another update. The real challenges in this sealed room are high CO2 levels that won't drop at night (no venting in the room at all) and low humidity when all of the lights are on. I would love to crank up the lights and really rock these things as planned, but VPD will be out of whack and may stress them. I chose to keep the lights at half throttle and keep the two mini foggers running full time.
I cut the light back to 350 μmoles because I couldn't maintain humidity above 40% with that many lights on. Both foggers were running full tilt. Today the humidity stayed around 55% when I turned on the some more lights and brought the light back to 500 μmoles, so I'm keeping it there. Until I get the new fogger, I'll have to trade off light levels against ideal VPD. I think 55% RH is a fair compromise against increased light. We'll see how they like it.
PH is swinging up and nutes dropped down. Topped off and adjusted nutes up to 280 PPM and pH is @ 6.40. Looking good near as I can tell! Roots are just starting to hit the water. :cool:
I found out that new seedlings can easily tolerate if not thrive @ 350 μmoles (in my environment anyways). In fact I'm betting they will happily grow under 500 μmoles if the conditions are good. All bets are probably off if the leaf temperature is high though. I'm keeping them @ around 78 - 80 with lights on and they seem to like it there.

What kind of mini foggers are you running? My experience is the single puck style is too small. I have 6 in a tote and it barely keeps up with my 1-ton mini/3k vented hood rooms. Watch your dewpoint vs. humidity so you don't start sweating. If I could do it again I'd start with 10-heads and go from there.
