Outtake air: Vents VK 150mm, 495m3/h
Intake air: passive
Running air: Hurricane Box Ventilator, 30cm (12")
Filter: Max Carbon Filter, 700m3
Hydro system: YaRoots, X-Tank 10 (drip irrigation, much like the wilma system, 10x6.5L pots & 95L reservoir)
Stream 700 Water Pump (730l/h)
EHEIM 200 Air Pump (connected to one big airstone + 1 diffuser)
Water control: Multi Meter (Digital PH + TDS (PPM/EC) + Temperature), all in one.
Air control: Digital Indoor Thermometer + Hygrometer

Growing medium: Mixed Clay Pebbles (Hydroton + Green Label's Hydrorocks)

Strains: 3x Short Stuff's Onyx
1x Samsara's Automatic Ultraviolet
1x G13's Diesel Auto
1x G13's Blue OG
1x Barney's Farm Auto Pineapple Express
1x Barney's Farm Laughing Buddha
1x Barney's Farm Liberty Haze
1x Dutch Passion's Power Plant


For the seedlings i have:
Propagator Pro
Spongepots from GerminationKit

Nutes: Main: CANNA line (Aqua Vega + Aqua Flores)
Extras: House & Gardern's Roots Excelurator
House & Garden's Drip Clean
Growth Technology's Nitrozyme
Advanced Nutrient's VooDoo Juice
Advanced Nutrient's Bud Ignitor
SuperThrive
CANNA's CannaZym

My tap water: 7.30 PH
170 PPM


Books i have read: Jorge Cervantes's, Marijuana Grow Basics: The Easy Guide for Cannabis Aficionados
Greg Green's, The Cannabis Grow Bible: Definitive Guide to Growing Marijuana for Recreational and Medical Use

Will try to put HQ pictures, when the plants develop.

Also, i have no idea what am i doing, i know in theory but in practice i guess it's a whole new world. I have read extensively in the books and in other grow journals and googled all the questions that popped in my head. If you have any advice about anything, or you think you could have done something better, please feel free to post.
Also if you have any questions, i will answer them as soon as i can, so please feel free to ask.

Grow Status:

The grow room is vaccumed cleaned, complete and operational;
I have washed the clay pebbles thoroughly, and i am now keeping them soaked in PH 5,5 water, almost 24 hours now, then i will transfer them into the pots and let the system run only with ph water until i can transfer the seedlings.

I will put the seeds to germinate into the propagator later, after i see that the whole system is truly operational.
Also, will not use any nutes, only ph 5.3 - 5.8 water, until the 3rd set of leaves develop (is this ok?). I will be vegging them for 5 weeks, with 24/0 light.

Bath full of clay pebbles, a nightmare.

Grow Status:
I changed Samsara's Automatic Ultraviolet with Delcious Seed's Critical Jack Herrer.
All seeds germinated Hope they will stay happy.
Measured the reservoir and found out it's capacty is 80L, not 95L as i initialy thought. Right now it is loaded with 50L of water.

System up and running on PH (5.1) water for 3 days.
Seedlings are getting almost ready to go in the pots.

Now preparing the system for the seedlings. In 3 days ppm went up to 280 and ph up to 6.5, i am now lowering the PH to 5.8. Also PPM have risen to 310, after setting the PH.

Laughing Buddha is almost ready, more are following:

Grow Status:

Air Temperature: 24 degrees celsius
Air Humidity: 40% (it is low, i am spraying water all over as often as i can, the flow of air is good, what can i do???)
PH: 5.6
PPM: 350
Water Temp: 21.0
Feeding: 15min/4 hours

So i transfered Laughing Buddha, Blue OG, Power Plant and Critical Jack Herrer. All of them are looking good except for Laughing Buddha that seems to be dying. It is bent over 90 degrees from the root. I am now trying to support it with a metal stick, hope to see some improvement. Strange enough it seemed the most healthy at the start. Does anyone have any idea what might be the problem?>> I do not want to lose it.

Also, Short Stuff's Onyx are looking good, will transfer them in a few hours. Auto Diesel and Pineapple Express seem healthy too.
I have a problem with Liberty Haze. It germinated, but didn't root, the little white wire is very thin and i don't realy know if it is at least a little in the ground. Also it is bent all over and the shell is still attached. Any advice???



Laughing Buddha on life support:


Liberty Haze with problems:

Grow Status:

I moved the 3 Onyx and Auto Pineapple Express and i put 3 of them on support with a little iron stick (they seem they cannot stand on their own, maybe i transfered them too fast??). I am feeding them for 15 minutes after 4 hours break. They are in clay pebbles.

Grow status:
PH: 5.8
PPM: 360

Diesel Auto seems ok to transfer also. Liberty Haze is still lost.
I put the spongepots directly in the clay pebbles. Should i buy some rockwool cubes and transfer there instead? Or could i go like this? Some advice, please .
Also i am keeping 1000w HPS light at 85 cm distance from the seedlings. (I don't have CFL)

Grow Status:
PH: 5.9
PPM: 370
Air temp: 24 degrees celsius
Air Humidity: 30% (low, i just put a jar of water in there hope to rise it a little)

I just moved Diesel Auto from the propagator to the pots, straight into the clay pebbles. Only Liberty Haze remains in the propagator, maybe she will fight to save herself.
All of them look preety good, hope they will grow up happy.
Tomorrow i will buy a MH 1000w bulb, as for now they are on HPS and i know is not that great for them.

It was a bit early to transplant them when they are in their seedling phase you need to limit their stress. Also, I'm not sure how far 85cm is but I know 1000W HPS is TOO MUCH light for seedlings. You are wasting electricity and also burning and stressing the delicate seedlings. Get yourself a nice cheap compact floro above 5000K or best bet a T8 6 to 8 tube setup for those little girls and save energy and their lives. Under floros you can keep them within a few inches without trouble. Last option is to move that hot ass light far away from them, it should never be closer than 2ft TO A MATURE PLANT. Hope this helps. Keep PH at 5.8 for Hydro

That light will kill them all. I know its been said but really that needs to be addressed, better to put them in a window sill than under that 1K. CFL will work great, judging by how much $ you spent on setup and genetics its no problem to go grab some. TODAY.-S0uP

hey, man! please, answer me this question
is it too much noise that vk 150 exhaust is making? i am planning on buying one and i am not sure how noisy it is
thanks!
