Its not Heath's trees, they're bobblebeds... 3 plants, each will be over a lb, guaranteed!

I know its not vert... Just saying the possibilities are endless, and don't get hung up on mimicking Heath to attain your goals.

Listen to Bobble, you'll only grow more potent and larger yields......I did.

Bare Bulbs + Adequate cooling for the win!

Okay so thanks for that very informative reply. I'm curious -- if I have ambient room temperature of 65-70 degrees F (it'd be grown in a bedroom dedicated to growing), will one high cfm fan pointed up from under the bulb really cool the bulb properly such that the temps don't exceed 85? I have a chiller so can keep the res temps down, btw.

I would say ppk, because root root is much less likely, for one. you don't need a chiller. I believe the cost of the build is cheaper( everything can be sourced at Lowe's or home depot). if you are at all diy inclined this build is easy once you understand the parameters of the system. I've never grown rdwc, so....

Yeah the chiller is definitely the drawback to rdwc since it costs a lot and also you're adding an extra couple hundred watts to your system (size-dependent). I think they're quite excellent if you can control room temps well and thus forgo the chiller (res temps below 72 F seem to work).

To get back to the thread topic, Heath's system seems to be a high flow top-fed RDWC, with the DO being generated by the waterfall effect through hydroton. My tree plan would be to replicate that using 27 gallon totes, uniseals to connect the buckets with pvc returns, 10" netpots, etc. I'd add a bos hog air diffuser in each tote to help with oxygenating the roots, and run two totes in my 5 x 10 tent. Keep it simple.

I like that he uses Ionic nutes because they're so cheap and also it seems pH stable. I had been using Advanced Nutrients stuff (I like the pH perfect tech -- it just worked and I never adjusted the pH even if it went up to 7.5 ... enough buffers to ensure nutrient uptake at a broad range).

SRGB, DHF, FlowerFarmer -- thanks you guys for all of your input. You all rock.

Forgive me if this question is rather retarded, but how do I find a bare-bulb fixture that isn't attached to a hood or some such?

From what I have learned reading these forums, basically a PPK (passive plant killer -- not sure why it is called that) is a hydroponic system in which the reservoir sits below the media and a "wick" is used to draw the nutrients up to the media, and the wicking action of the media (e.g., coco) further distributes the solution throughout the entire root system. Here's a schematic of one such setup:

I'm sure this could be much better explained by people on here (and probably has been!). Just search the forums.

So what do the wicks consist of? Whatever medium is used?

you just buy a cord set, that are between 15-30 dollars depending on where you get them. it's just the socket and cord that plugs into the ballast.

A high CFM extraction fan hung near the top of the room exhausting all of the hot air out.

A LOW CFM fan underneath the lamp gently blowing upwards at the bulb creating a channel of air to take that heat upwards where you're high cfm exhaust fan can extract it.

You don't want a high cfm fan blowing up at the bulb. This air will slam into your ceiling with force and be pushed/looped back down and around your room.

Gentle fan upwards.. as large as possible extraction fan. I've always maintained a minimum turnover rate of once a minute. DHF and others suggest even more so at twice per minute. Makes a hostile environment for mold/pests while ensuring you can match or come close to your intake/ambient temp. Certainly can't disagree there.. it's a lot of air!

I'm a huge fan of the Can-Fan Max 10" - 1000CFM. Moving forward if not running sealed w/ co2... I'll add these as exhaust on Can Filter 150 until temperature is kept in check. In a roughly 12x12x8 room with 4-5k one will typically do the trick.

Thanks for the info bro. Recommendations on fans to use pointing upwards? Perhaps this one?

Ahh sorry bobblehead I just realized you said this was 3 plants. That canopy makes it look like a lot more! I had considered scrogging but I think actually going vertical seems more promising....

Thanks green_thumb. I have the cheapo Apollo Hort stuff from Amazon which are hydrofarm. I'll go check at the local hydro shops to see if they have anything similar.

Now how to cool those bare bulbs?
