New Grow Rm Constr - SOG B-52

Here is my new grow room:
Dims - 8'x6'x7'
Veg - 4 bulb 2x4 T-5
Flower - 600w HPS Lumatek
Vent - 435 cfm centr fan

Here are the basics for now, I will add to this more as time allows.

I am going to model my grow after Al B Fuct how-to...

here are a few pics of the room...Studded, then lined with 4 mil plastic, drywalled, taped, and painted flat white.

I am working on assembling the tables and installing my fan. I started with 10 seeds, B-52 from Nirvana. I germinated half last week and the other this week. I lost one after germination, it was very weak. I have read Jorge Cervatntes cover to cover twice and Al's threads in the Hydro section. I have my seeds in rockwool cubes and keeping them at about 30 g with 5.5-5.8 pH water, no nutes right now. My tap water is 122 PPM. I did have a period where the pH went up to 6.4 for a few days and didn't check, I have been more consciencious about that now.

Two week in and I think I am having some troubles, I noticed the edges of the leaves curling up and now they are brown. Do you think this is bulb burn or not enough water? See pics...

I asked about this in the hydro section and the responses seem to agree that this is a result of heat stress. I was thinking that the cubes felt too warm, so this helps confirm my suspicions and I shut off the heat matt.

nice man im a grab a seat for this grow

Thanks, I have so much stuff to post, but not much time to do it. Feel free to ask any questions and offer advice if you feel I am doing somehting wrong or could do something better.

you got it man!!

IM watching the mods come on and grow get bigger on this one for sure! Nice framing job!

So 3 days ago, I removed the heat matt as the root zone's temps were soaring and my babies were getting cooked. I got the temps down and the root growth exploded over the past 2 days.

I also changed from 5.6 pH tap water to the following solution:

-tap water (120 ppm)
-15 ml/L 3% H2O2 (horticultural grade H2O2 is no longer available in my area, so you have to go with drug store variety)
- 3/4 the recommended nutes for seedlings (300 ppm recommended, I used 220ppm)
-adjusted pH to 5.6

The grow light they are under right now is a 120W gro bulb. They seem to be stretching a bit right now. I am anxious to put them in hydroton and in the trable under my t-5s but I am waiting for more roots to pop. I think my heat ordeal set me back about a week. So I will give them on more week as I am now 2 weeks from germination.

I am very happy with the way the seedlings are growing and rooting now. I increased the moisture content in the RW cubes to 35-40 g and it seems to be working nicely. I also changed the tray the cubes were sitting on to a white plastic tray and removed the heat mat...temp are right at 76-78 deg and seedlings are rooting well. I will probably put them into the hydroton this weekend.

I installed the 600 W HPS and Lumatek Ballast as well as the duct work. I will take some pictures and share with you guys shortly. Thanks for coming for the ride!

I have installed my 2 x 4 table and t-5 vegg lights (4 bulb 2x4 t-5 54W w/ 6500K tubes) I also hung my 600W HPS, ballast, and ductwork. I kept the ballast inside he room because my setup has very cool temps and I don't foresee it being a problem. If it it, I will relocate it. I plan on running my 6" fan 24/7, it will be wired to a fan control and thermostat in parrallel, so when the t-stat isn't running the fan at full power, I will have it running at 40% so air is contstantly moving.

One thing I noticed is hat I need to rework my outlets. The timers don't work with the quads so I am going to split the outlets up into individual duplex outlets spaced to accommodate the timers and cords.


This needs some reworking...




I am also having a problem with my GFI on circuit #1. For some reason it trips from time to time when devices go off/on, and I am definitely under the rated load...might be a bad GFI. I am going to switch it out.

This runs through a window outside and it 100% air tight and light sealed.

....my precious....

My utensils and the Flora Nova grow nutes I am using...

This TDS mieter is a POS....I have had a bunch of problems with it. Yesterday it stopped workin, it wouldn't come on. Then it came on but the readings were all whacked. Finally I tried it again an the readings made a little more sense, but I am not confident in it anymore....I took readins on the nute soup when I set up the table 2 days ago. I had 120 PPM tap water and added 500 PPM nutes. Now the tds reads I have 700ppm nutes in the solution after 2 days of running????

Here are my healthy plants....they were started from seed 3 weeks ago. B-52 from Nirvana. I had a little heat mat issue that cooked the roots a bit and set me back about a week.

I went with a larger res fro this table than I hd originally. My nute soup was set at day 1 at the following:

PH - 5.4
120 ppm tap water
500 ppm Flora Nova nutes
13 ml/L H2O2 (3% H202) - I need to find some hort grade 50% H2O2

Day 2 my TDS was messed up..

PPM ????
PH-5.6 adjusted to 5.2

Day 3

Nutes were 700 PPM (is this my messed up TDS?)
PH - 5.3

So this is where I am at today...I very much appreciate good advice from others, I am more than open to suggestions and constructive criticism. Thanks!

PS - Do I look alright for 3 weeks from germination? The stems look a bit stretched because of the initial lighting, I hope they sprawl out now!
