How do you mount COBs on heatsinks? Picture please.

I used.kapton tape as my self tapping screws didnt fit the holes i drilled for the holders...i bought some new smaller self tapping screws so will fit the holders this weekend to hold the cobs in place....

Day 13 for these...got rid of the other 2 in smaller pots to a friend as he had two seedlings die...i think these are going to need the extra space anyway! He is an old school grower who only believes in HPS/MH lights so he said its going to be really interesting to see the outcome of both as we use the same nutes...he has the experience under his belt though...he said hes hoping it will prove to him that LED lights work as good!

I believe they are drooping as the lights is to low...ive raised it another 3 inches and will see how they react...

After raising the light a little the leaves have started to perk themselves up a lot...the 3 Bears OG seems to have developed the pistils already at day 15...is that way to early and its stunted itself or is it quite normal? I have seen pistils at day 22/23 before but not this early...the small hole in the leave is through me dropping my phone a few days back...the tips of the first set of leaves are starting to go yellow...im assuming its not a sign of any nutrient deficiencies as the rest of the plant seems really healthy?

Day 16 for these now...i dont think they would have ever got to this stage under a HID light...especially the 250W i was using originally...really excited for the results now!

I'll be dropping a 3BOG in a few days, can't wait to tail your grow. Good luck bud! :pass:
 
It seems like shes gonna be a winner! Havent grown or smoked any mephisto but the 3bog has got some excellent reviews...will be nice to compare the grows to each other :)

This is at the end of day 17 and going into their dark period before starting the 18th day...i love autos they look so naff for 2 weeks then really pack on noticeable growth every day...next weeks gonna be good fun to watch! After feeding with 2ml per 2L of plant magic magne-cal the slight yellowing in the veins are starting to fade...

I really need to sort out a method of dehumidifying the tent as well as its completely sealed with no extract...ive bought some hanging bags but i believe its going to need a dehumidifier im going to need to somehow duct in and out if they dont do the job...

As im running a completely sealed tent ive been paranoid about co2 levels for photosynthesis so i invested in a second hand controller...its basic and doesnt meter and supplement on the metered PPM levels in the air, you enter in a rough volume and it injects co2 based upon this...it was cheap and i dont need excessive perfect amounts, just enough for them to grow...
