Two Trainwreck's 400w HPS, LST, Closet Grow
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.
Here’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 can’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 cfls’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 it’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.
I’ve also been LST’ing a little bit this last week. I haven’t decided yet, whether I will SCROG or just continue the LST.
