Three months for 88g under LED
Thank you Tobor, thats all I wanted to know
Hey Tobor, job well done. I'm glad you too have a changed mind about LED units. I wanted to comment on a post you made about me in response to one of my threads being linked on here. I've worked with that strain, and if I doubled up the plants, the buds density decreased too much for my liking, seemed less potent and tasty and it only yielded slightly more.
I ran about 60-70 watts/sqft and doubling that would bring it to about about ~35watt/sqft. With a MH, I needed it up around 70. I chose the MH for the taste, and potency which I found to be better with that particular strain. I have, and still do primarily flower with HPS but when you've done as much growing/experimenting as I have done, you find some plants respond very well/even better to MH then HPS. It also kept the stretch way down.
Again, good looking grow.
Dankenstien: LED Growing is not HID growing. So while you may have experienced different results with HID and temperature, it doesn't mean that also applies with LED's. The reason you ran 80-84 F before, is that HID's throw out a TON of radiant heat, whereas LED's do not. If you went higher with your HID's, you'd likely fry your plants. Because of the lack of radiant heat, plants grown in a LED environment need higher temps in order to achieve the same levels of transpiration (plant respiration), which directly affects the rate of photosynthesis. There is a break-off point with temp where going hotter doesn't equal faster growth rates, but that temp is well above 90 with MJ and LED's. In fact, running your plant at the hottest setting they are optimized for will guarantee you higher yields and faster growth. So until you've got about 5 LED grows under your belt, please don't tell me how to recommend our lights and environment settings for our customers. Thank you.
LOL 95 degrees!!! If I were you I would never run my plants at 95 degree's. What people need to understand is as the temperature raises your plants stomata closes letting less co2 in so adding co2 to a hot enviroment doesnt mean it gonna be fine and dandy since your adding co2, if you want to see improvement from running co2 you need to keep your amibent temp within the 78 to 84 range. Running temps above 84, co2 is needed just to keep growth at a regular pace. Not to mention what the higher temps do to nugget density and other issues it causes. So long story short just because your adding co2 doesnt mean its ok to run temps in the low 90's. Ive seen better results with same strains in properly vented tents that run at 81 when hot compared to sealed co2 injected tents that run in the high 80's. Just my opinion but If I were you I would just add a ventitlation fan 24/7 and keep my temps below 84 at all times rather than seal that room up and run co2. Remember just because they are LED's doesnt mean its gonna just with zero heat, no matter what with a sealed room and that many lights the temp is gonna be running hotter than is desired.
