Whats Changed. LIGHTING - 18/6. - LIGHTS - 100W/2700Kx2, 100W/6500Kx4 - LIGHT HIGHT is at 12in above top of plant base. WATERING - keeping moisture levels at 7-7.5Max is crucial. Do not go above 7.5. At all, Ever. They can start wilting about 5.5-6.0, so make sure your watering is constant (This is at temps in the 80's with humidity in the low 50's to high 40's.) during the day, and low to mid 70's at night, with humidity in the high 40's to low 50's. These plants LOVE hot heat. 80's is great for this strain. Just keep up the watering and you'll be ok.
Man I love your attention to detail. We need more grow journals with this scientific approach to growing. Monitoring as many variables as possible allows you to really know the health of your plants and how to fix things when they go wrong.
- This is exactly true.Hey altfour. Sorry to see your struggling with your first time, but as anyone will tell you a good journal makes every grow a success. It seems like you are learning a lot and I like the way you use the journal for your own notes. Personally I keep a separate journal but Im sure you are doing this as well seeing how thorough you are
- this is true as well. Rockwool is easier to tell how wet and how much to water. The pots are good and well watered, but the rockwool is dry as a dasiy.I will add my thoughts based on reading your journal:
When it comes to watering: its not the amount of water its the frequency of watering that causes problems. That may have been your earlier problem with the rockwool. I have experienced a similar problem using a similar medium.
- exactly right.If you are still experiencing water issues which i think you are because I saw one of your babies bow out, I would say your pots are some what big for such small seedlings. You may have to water them more often because they cant pull the moisture from the lower areas of the pot. This leads to them not getting enough water because your scared to over water plus the bottom soil is probably getting mucky. This is speculation of course and I am not a pro.
- Right on the nose with this. And thank you for the rule of thumb. Noted.With regards to lighting, It seems like your plants stretched some, and you now know that was because your light was too far, a good rule of thumb is lights are never to close if you can keep the back of your hand at the same height as your canopy comfortably. You can get the light up to 3 or 4 inches away using fans and other cooling methods.
- PH is at 8-9.9. Very high. Although the test was at two weeks. I've leeched the water once, and haven't tested it since, but i put a steady sprinkle every watering of insect frass. 2.2.2. I'm sure its about 7 now. But you were right, some of the roots were nearly getting water. This is because of the rockwool and pot size. And speculation of watering/when/how much. Got a Moisture Meter now, and did notice that it was the roots, after i lost flower#1. With how small the roots were for the time being planted and watered. That was a great plant. I miss her =(.Also, Make sure to test your PH, I dont see any mention of it in your notes, but maybe I missed it.
If youre using tap water you can just let it sit a day or so and the Cl- leaves as Cl2 and the pH will neutralize. Or if thats not fast enough use those droplets for fish water.
- I wish I would have read this. Cannot wait until my roots get stronger ive killed almost 3 flowers =(Also I almost used rockwell when I was starting cuz it seemed easy to grow seed in then I found a forum that said its only for hydro.
- I have (1w leds x 300W @ (blue/red ~420-450nm blue / ~620-700nm red) and I do have *3x6500 *2x2700 and *1x3500, all at 100W. on all flowers.LEDs will be awesome for flowering, those cfls have way too cool a color temperature for it (5700K), you would need a 2700K or something at least worm below 5000.
Dang you are set for a great light show! You should def post a pic of your flowering set up when you get to that point.
Those 3500 and 2700 are in the perfect spectrum for flower, as cannabis uses more of the 620nm peak from chlorophyl b and the 680nm peak of ch a at that stage of growth. LEDs are my favorite though! A good LED gives the plant exactly what it needs, no wasted energy (ie heat, useless spectrum).
Whats a 12V set up?
Im not very good at watering either..
