I didn't like the tape either.
I noticed a few areas in the construction that could be biult upon.
As long as the pieces work like they say then this will be my starting point. For drivers and light strips and stuff.
i never used tape building the cobs. i know a few guys who swear by the paste. the tape is convenient, that's its main selling point. you can use the paste for multiple things as well.

Just subbing. Been wanting to try Hempy too. Also want to build an LED, but way too much money.
they are not too bad now. can do them about a third cheaper than 2 -3 yrs ago. may just be our dollar caught up a bit tho as i buy electronic stuff mostly over borders.
it is well worth the plunge Fert.
er, both hempy and the light that is
Curious what kinda of heat from those strips

Sign me up. Never done hempy and haven't really looked into it so it's a learning experience for me.

Welcome.
I'm surprised that Hempy is not way more popular than it is.

are you running separate veg and flower spaces ? if so do dedicated veg / flower lights. otherwise maybe shoot for a 3000k/3500k light built as full spectrum. i made that compromise on my cob builds.
I do separate lights for each stage, much easier for me
now that i have separate spaces i am thinking of reconfiguring.
If I build two of these.
Useing 3000k strips for one and 4000k strips for the other, alternating the 8 strips. To make one QB with two drivers so I have veg and bloom settings or should I just use one drive with one dimmer or potentiometer?
Thoughts?
There are far more knowledgeable than myself when it comes to building these things, but at least from what I've seen, anywhere between 3000-4000 is fine and there is not a big enough performance difference between the two ends of that range to justify the additional expense of the redundancy. Pick 3000, 3500, or 4000 and you'll be fine using the single spectrum start to finish. Personally I ended up with 3500k. That was more the choice at the time because the better COB's were of that spectrum. Now that QB's have become so popular, and they make theirs as either 3000 or 4000, 3000 has become more the rage.

Is it a 32"x32" like mine? I did the 3x3 build under the guise of "you can never have enough light". The 3x3 bulds are actually 24"x24" so they fit inside. You can always run it a bit higher or turn it down via the pot if needed.

It's 30"×30". So jump up to this then. Sounds like a plan.
