Drip frequency depends on your media. Rockwool needs much less than clay pebbles for example. Im a total noob so dont know enough to advise really.

I agree with the guys above regarding value, but I really like the design. The low profile could be very useful in a tent. I've beening using a pots-on-tray-on-res type drip system and the small pots and tall profile are the biggest drawbacks.

What about led t5 replacements like the transcend models? they seem to cover all your requirements. Flouresent t5s put out a surprising amount of heat in a small space.

Boom! 3rd reply. "Price is not of as much concern as accuracy and quality/longevity. " No fuck that. Spend X hours learning to build and source parts for a diy kit , then build it. WHOS CARES HOW BIG X IS, YOU SAVE A FEW HUNDRED BUCKS. EVERYBODIES LIFE SITUATION IS THE SAQME. WE ALL HAVE...

Your point only stands if you put zero cost on your own time and labor. And dont say it only take x hours to assemble a light. if someone is choosing between a commercial fixture and a diy cob build, the cob route requires hours and hours of research. Those hours must be added to the cost of the...

Found a solution.I cut the arse off a bucket, dropped it in a 12" vent for an airtight fit,put box fan on bucket. Thusly...

For the beginner Leds are extremely attractive for their simplicity. You just buy one item, the light, and plug it in. With HPS you have to pick a bulb, a hood type and shape, ballast. Its extremely intimidating. If you've been growing for years you may not understand how important that is.

Hmmm, that makes sense unfortunately. I thought more co2 = good regardless of anything else. On the plus side, 80 bucks!

Most people seem to agree ambient temps can be a few degrees hotter with leds than hps. Anyway, just look at your plant. I see zero signs of stress or an issues really. Isn't he at the upper limit for light, any more would be overkill and risking bleaching? Its only one plant and his ceiling...

Looks beautiful man. You should expect to get more than 2 ozs from 350 wats. When estimating yield the starting point is amount of light. Other factors act as multipliers to that. co2, eenvironment,, nutes etc. Heres a thread where people report their grams per wat on their led grows. Lots...

With so much light you'd probably get great value from one of those 30 dollar co2 bottles. By all accounts you should get easily 15% more yield for no extra effort. The plant could take higher temps and heavier feeding.

Is it surprising that radiated heat is such as factor under high efficiency cobs?

Are they any good for a res inside the grow room? you'd need to step up your venting right?

so tents -> filter ->fan? Thats easier on the fan is it?

Hi guys, Is this possible. I was planning on one of those big floorstanding filters,a fan sitting on top and a Y connecter straight on top, one for each tent.The left duct splits again into the veg and flower comparments of the Secret Jardin L120 (link) tent on the left. The space between the...

If you're only interested in achieving an even spread with a few lights of the same type you only need a lux meter app on your phone.

Looks like they're damn good light though.

Do they have eu distribution now?

Warning: Im a huge noob on his first grow, all of that this is hearsay. I read somewhere the ambient temp in your room needs to be higher with led than hps to maintain same temp at leaf. Even allowing for the differnce in total heat output theres much, much less heat radiated to the leaves with...

Dude, talk to @robincnn from https://northerngrowlights.com/ I just bought 2 Photon's from the Eu. Shipped Friday, arrived today ( dhl) . Customs etc were handled in an extremely efficient manner. I couldn't be happier with the lights. Had a minor freakout when I thought the fans stopped...
