Must have been done. Shall search google. Semiconductor works better as cold as it can go without cracking due to contraction.

Drivers are cheap. Just need some good chips

I guess warm white still wastes power in unuseful spectrum

The Pelter chips eat a lot of power too. Might be better of starting with bin 1a chips and compression cooling. I have a nice peltier block to use up though. Any good price sellers of red and blue leds? Only bin 1a on eBay are whites.

Has anyone opened up a UFO to see the guts? Would love to see some teardown pics

Hi. I have been wondering about the ratings of led grow lights and why they are all only run at half power. Is this just to extend life or for heat dissipation? How would efficiency change running the diodes at FULL rated power? I understand this may need upgraded power systems and cooling. I am...

Shulgin made THC from orang peel and lichen heated in tin foil

Diggings in an ancient thread here. Has anyone heard of Cambrian genomics? If you download some software and sequence of mj and another organism you can splice in the gene sequence in software. Upload it to cg for a thousand quid they laser assemble the new DNA and post it to you. Then you...

Hi. Had to start this lot in less than ideal circumstances and now 4wks from seeds in formulex all the way at ec 2.0. Now put into 1212 and want to change to ionic when buds appear. Can someone recommend if I should dump out the tank and refill with ionic bloom keeping ec 2.0 or shall I step the...

Nice one. I will follow that advice. This is not the time to experiment.

I only use clones as a rule so not used to sexing in situ in hydro environment

That's a really good tip. Do you think when I pull the boys and redistribute the ladies I should do it after a soak so roots are wet, or switch off the pump for a few hours and let them dry a bit. I imagine they could fracture easier while fully hydrated. Like its easy to dehydrate a plant a...

As an alternative to net pots you can go to a greengrocers or cafe and get net trays that mushrooms come in. Very strong and free! I cut them into quarters and zip tie them together to get 2 big squares from each basket. They have stubby legs in the corners to keep them just off the bottom. Also...
