Hahaha... that's hilarious... every post I have ever seen about them was somebody bitchn about the seeds or saying how they threw out the plant
So far so good here.. I think the idea of giving them away was 1) they were cheap and 2) that people would use them for crossing..
Yes.
I got those seeds too from freebies , i heard nothing but bad things about them and how people just cut them down during flowering cause they sucked so bad. I also heard bad things about the Hawaiian skunk haze freebies they gave out, i got a bunch of those too.Hahaha... that's hilarious... every post I have ever seen about them was somebody bitchn about the seeds or saying how they threw out the plant
I have 9 more sitting in my room if you want to try another
Also the Dream Machine they gave me absolutely sucks... I have them in veg. They are barely hanging on.. Took a long time to pop and now they are about 2 inches tall when my other plants are already headed into flower.
Just an observation with 3 years of cobs. I find the more the light the quicker the finish. A week or a little more. I like to run ~700w in 15 sq ft. 16 3590's. I do keep some distance maybe 16" when at that power level and I try not to put a cola directly below a cob. It will bleach at that power. But it gives me very good penetration. But yes the finish times seem to me a bit quicker. ymmv
Cheers, forgot to mention that, I ran them at 16-18" above canopy in both configs. It does seem to be what's happening, will keep that in mind. Not a biggie as the one's with the lower amount of light produced great and quality was the same, just took forever to finish compared to previous runs.
^^
Ah neat, I was wondering if 600w in my 16 sq ft would be overkill but it looks like I'll be able to max it out at 16" above canopy?
Lord no. Just a small personal grow. I do have a meter somewhere. Could be 1300. But with cobs somewhat brighter in the center due to the close spaced LEDs on the die I try to hit the lower branches with the center of the cobs and the tops get side lobes if you will. That way it seems my bottom is much better. I have a very tight closed in stealth area so I rotate the plants to get the light to the bottom. Never did the calculations either. That's why I'm hoping the panel LEDs will help with the hotspots. Larger Les. I hope so. But will I have the penetration? I will run them side by side. Actually the 2 3590 panels I built will run a killowatt total. But it seems to be the best I have found for my area at around 700w.
Play around and see. For me 700 in 15 sq ft is about the point of no increase. But pointing the cobs toward the bottom seems to work for me.
Do you ramp up the wattage as plants grow, or just start blasting at full intensity from early on?
I vote to ramp it up slowly for the first few weeks of veg... have to figure out what your plants like. They'll tell you..
I start at 400 w but up 24 to 30". Then lower and increase. I have found if you hit them with to much light with small root systems they can't get enough nutrients for the root system at least in promix. I have played around with foliar spray in veg early on until the roots get bigger in the 5 gal. But I just wait and increase over a week or so depending on plant. I have 4 "zones" I control the intensity in. I'm at 700 now at week 4 ish of veg and 20" or so above they are around 24" tall depending on strain. The larger leaf indica's seem to burn easier as well. That is WALL watts btw. Running 58% ish efficiency at the les.
Yes a par meter Take a measurement for each linear foot at a given height. Take the numbers and divide by the total number of measurements to get PPFD.
Very cool. Thanks much! Seems like essential equipment for growing with LED's. Well maybe not essential but good to have.
Exactly. My DE HPS is putting down 1000ppf-850ppf in the center 2ft. About the same from the HPS. And cobs are 1100-1250ppf around the canopy... It's great to know how much light is being pushed so you can have lights way closer than you would without it. De is at 1.5 -2Ft compared to the recommended 3 for a small area it's awesome
I have one and fiddled with it a bit. Fleabay has them cheap. If you want they sell some DC wattmeters on fleabay that are good to 120vdc I believe. Current donuts and voltage in terminals to do the p=e*i calculation.they run around $25. I just built a kick butt light hoping to expand some day if legalization happens. Haha Anyway I watch the plants. Look for stress etc.
