Two Trainwreck's 400w HPS, LST, Closet Grow

[bigtopsfinn]

First, I have to thank Cannabis.com for the great success of my first grow. I had some problems with temps (being able to close the closet), the smell was leaking out of my apartment, and I didn't have anything to measure pH.

I invested a couple hundred euros to fix these problems, and so far, everything seems to be going good.

Hereâ??s the list:

Seeds: Feminized Trainwreck from Greenhouse Seeds Co. Flowering time is 8-9 weeks (Last grow with one of these turned out very nicely!)
Soil: Biolan Musta Multa (N-100mg/l, P-60mg/l, K-400mg/l). I also put in about one quarter/one third vermiculite. I canâ??t find perlite here, and the last grow I used just soil and it was terrible to try and flush it. The vermiculite holds in the water and allows the water to run through with ease.
Nutes: Canna Terra Vega 3-1-4 (for veg) , Canna Terra Flores 2-2-4, Plagron, Green Sensation Top Activator 0-9-10 (Flores for flowering weeks 1-6/7, the top activator for weeks 2-6/7 of flowering
Light: 400 Watt HPS with Cooltube 12cm x 39cm long
Ventilation: 1 RUCK Tube fan RK100, 220m³ per hour, (129cfm), 10cm & 12cm aluminum duct (possible coming later: computer fan to blow over the tops)
Odor Control: Active Carbon Filter, 250 m³ per hour. 50cm long with 10cm connections, approx. 2,3 kg active carbon filling
Closet/Cabinet: 57cm x 57cm x 172cm tall (22.5in x 22.5in. x 67.5in.)
Vegetation: 24/0 light cycle

I sprouted these 2 Greenhouse Seed Co. Trainwreck seeds on Jan. 15, planted them in soil on Jan. 17, and one surfaced a day or so earlier than the other.

I first kept them under a couple 11w cflsâ??s and a 21w floro tube for the first couple weeks. Needless to say, not nearly enough light and when comparing it to my last grow, I knew it was time to get the 400hps in there.

Now itâ??s been about a week since I turned on the hps, and a couple days since I started half strength nutes. Today I started giving three quarter strength nutes, and raised the plants closer to the light. They are now about 30 cm from the cooltube, 33-34 cm from the light.

Iâ??ve also been LSTâ??ing a little bit this last week. I havenâ??t decided yet, whether I will SCROG or just continue the LST.

nice looking setup bro. seems like the space might be a bit small for 2 plants but i dont know how trainwreck grows out, i'm leaning towards your idea of scrog over lst.

[bigtopsfinn]

Thanks for stopping by Animal. Yeah the closet got a whole lot tighter when I put in the fan and filter and cooltube, and another plant.

On my last grow I did the LST and it worked out well, but it was nearly impossible to keep all the tops at the same height. I've been planning for SCROG already, just not sure whether I could really do it. The advantage to the SCROG would be that I can control the tops (height/placement), but I know it takes a couple times to get it right. We'll see in few weeks...

Got some pretty decent drooping going on in those plants. What's up with that?

Not really sure... This happened last time also, but the leaves are very thick and feel solid. StinkyAttic said it could be because the reflection inside the closet is very good. I'm not too worried about it since last time everything turned out fine:jointsmile:

How do you like that fan? Does it give an approx decible rating? I have a similar 400hps closet grow going. A 75cfm computer fan exhausting my light works perfect now, but probably not when it gets warmer. I'll be keepin an eye on your grow. good luck - love that trainwreck.

Thanks jboog,

The fan has been quite a pleasant surprise up to now. I thought it would be louder, but we sleep 10ft. away from the cabinet, and the fan is on all the time without disturbing our sleep. I've kept mine on 24/7 for the last week, and its still humming like new.

The decible rating on the Ruck site says 57 for this model. I just noticed they have some other models, one with a 4-speed and one with temperature control.

Right now, my house is about 23 degrees Celsius, and the cabinet with the door closed stays at 30 degrees Celsius. Lower temps for flowering would be better, but I managed with these temps last time, no problem:jointsmile:

thanks for the info.

I'd definitely throw a little comp. fan in there. My veg 'room' is under a coffee table wrapped up in b/w plastic. I had two ladies vegging in there and I didn't rotate them for about a week. The one opposite the fan drooped like in your pictures above. A little more airflow and its leaves stood straight up. And I'm talking a tiny/silent 40mm fan...

Got a little computer fan and phone charger today. Gonna work on it and try to get it hooked up to the end of the intake piping, blowing on to the top of the plants. Maybe this will help the drooping, but I'm not too worried about it yet.

It's been 29 days since I started this project. I went ahead and changed the closet setup. Tried a couple different ways, but in the end I lowered the light and hung the carbon filter and fan above the light. Now I dont have anything blocking the light and have the full grow area, and my temps dropped a few degrees to 28 C with the door closed and the light on.

Plants have jumped up also since the transplant. I dont know if it was the addition of the small computer fan blowing over the canopy, the re-pot to 10L buckets, or the fact that I have been watering it much less than before or my last grow. (Last grow, I was giving water sometimes 2 times a day, now the soil still feels a little damp a couple inches down. I think its the vermiculite, which is supposed to hold in water very well)

Whatever the reason, they are looking much better now, and could be ready for the SCROG sometime next week, and then ready for flowering maybe the week after.
