9 x Dutch Dragon - 1 x White Russian - 600W HPS - From Seedling :-D

Looking great Maria! Very healthy looking plants and they are Hairy little girls. Nice. :thumbsup:

As promised - the new humidity & temp data:

Attachment 297963

Could be a bit warmer - but it's winter... Holding the temps @Night with a small heater - controlled at around 17 degrees Celsius. Days at 20 degrees Celsius (No extra heating - just the 600W HPS)
Do u think it's too cold ? Should i programm the temp. controller to hold 19 degrees at Night ??

And special Details for the Nerds: (like me too, i like this sh*t)

Attachment 297964

There are so deep details. I try to figure out when to water them through reading the data ;-) I bet this will work.... :rastasmoke:

Hope I don't wake up some haters because off posting such maybe not so necessary details ;-)
Just a girl and want to make everything right and nice :-D (maybe i smoke too much... *g*)

GB I'm curious about the inversely related spikes in temp and humidity about 3/4 of the way over (is there a way to label the x-axis?). Seems like an odd relationship between conditions at that point. Otherwise things look pretty good. Your temp.s are a bit on the cool side. I have the opposite problem in my flower room. In my grow room, I have several plants under a 400W MH, and for various reasons it is in the same temp range as yours here (16-20C). I notice that the plants are slow, overly delicate, and lose a lot of leaves, especially low down. They get limp and black along the edges. Now it may be that something else is responsible for that, but I am suspicious of my low temp range. It will be good to get some input from the experienced growers.

I know there are many factors involved in yield, but the grower friend of mine who is looking over my shoulder on my current crop, estimates my yield will be 16-20 oz. You can maybe compare the sizes of our setups to get an idea. Maybe. ;)

@Chromophore

Of course u can label the axis.. I will do that the next time... The funny thing is u noticed my daily check in the data.. opening the tent leads to fall down the temp at the leafs, this comes with fall down of humidity at the leafs... On the other hand.. A lot of warm air is going to the soil level (The sensor is 2-3 cm over the soil level) which comes with an increase of humidity at this level... This is really awesome.. I learned so much...

Are u excited now to get this tool in your hands ? I bet u check the tracking of your order every day ;-) Wish you fast delivery.

I plan to set up a second veg. room and take the outgoing air of the veg. box to the bloom box.. this should increase the temps.
I hate wasting energy by heating out energy through the window...

If it get's too cold by the daylight..
I rather would add a second 600W HPS than heating through the day...

That's basically the way I have mine set up, which is why my bloom temps are a bit warm (22-30C). My veg room is cold because it's pulling unheated basement air, which is probably 12-15C. The 400W just isn't enough by itself. I'm rebuilding the whole operation this summer, and environmental control will be my guide.

Kinda like this thinking out loud, Think our veg room needs to be warmer than bloom room. Veg room will not care about heater flash, and the lights could be on 24/7, not most be but could be. Bloom at a little cooler temps and you can get pretty colors that way. Can you move air the other direction, put heat in veg room, you don't want the young girls to slow down at all.

Nice to have a tech nerd around!

ranger that is how I am going to re-design things. I'm running 18/6 in the veg room so I'll push it to 24 and maybe that will help. When I rebuild I will put both rooms inside the same larger room, and each one is going to be sheetrocked and sealed. Then I can set up air and heat systems and be able to control things better. Right now the flower room pulls air from the veg room, which is actually in an adjacent room of my basement, and the air leaks in via spaces around central heating ductwork along the ceiling. The adjacent room where the veg is set up is actually my laundry room, and because of it's orientation in the house plan, receives little heat from the rest of the building. Definitely not ideal. But at the moment it's what I have to work with. Once theses two batches of flowers are done, I'm dismantling everything and re-building properly. When I move the current batch in veg to the flower room, I can shut down the MH in the veg room, so the flower room will be pulling cooler air. Also I may let the plants sit under the HPS for a couple of weeks to help put on some healthier growth.
