My big question after looking this over one more time is- does U channel really provide any additional heatsink value vs aluminum bar stock? It's not exactly an efficient heatsink design....there is definitely some extra value for stability for sure.

And physics wise you're dead on (I'm an engineer by education, IT dude by trade so I OVERENGINEER THE F OUT OF PROJECTS)... but in this case the lower load/more you can disperse the load across additional strips it will reduce the operating temp and increase the efficiency. It does add initial...

Based on this convo/my available funds. What I'll probably do is build just the basic light- 6 of the double layer F strips for now and keep the price down. Later on I can add supplemental lighting via strips/COBs/whatever with some minor reconfiguration. I'll probably take it for one full run...

I'd be running 6x 4' sections (not even counting the frame material) so assuming that scales with section length for my max power of 480w that's dead on. That's what you got for that cheap locally?

Solid advice, at a quick search such a business does exist lol https://tulsaaluminum.com/ Can't get pricing until tomorrow but that's whatever...I wonder how expensive it would be to get something like 40-4040 series with one slotted side. That looks to be all the Cypress 6/8 are built on at a...

It's a little of column A, little of B... I need more lighting and I'd rather do it for cheaper if I can. I also need to keep myself busy for sanity reasons (WFH since March) and I love to overengineer projects.

Birthday Banger and Lilac Diesel - organic/super soil grow. Almost at the end of week 5 flower.

Also not artificially add gravitas to this thread BUT I just noticed I missed a 0 in my budget for this paycheck (in my favor) meaning I have enough $$$ to order parts (or a light if I go that way) on Friday. That would probably disqualify me from the Mars Hydro cup (switching out my Mars Hydro...

I thought about it but I was nervous on whether nor not aluminum channel/angle/flat bar would be efficient enough in cooling. Where are you getting your U channeling? Just shopping around online and for channel big enough to fit the lights there doesn't seem to be much price difference (those...

I'm about a month out from having the budget for my DIY bloom build and I'm looking to finalize my design/start ordering a few parts here and there as I have the $$. Planning on using these 44" samsung F strips (could be persuaded to change based on pricing BUT I like how condensed these LED...

You have to post "X" times or get "X" likes before you can like a post. I can't remember the threshold but you'll hit it quick.

Lol yea when I read it high I was like "there's no way a bottom bud is ACTUALLY done before a top bud" and reversed it in my head. I'd assume the trichs are actually ripening as usual and it's just aesthetic for the additional white hairs @pulpoinspace?

Edit: actually looked at your grow journal and you're doing everything I would have with those plants. I think you're just struggling against the nature of plants with apical dominance and the limitation of LED lighting (canopy depth).

What kind of lights? How big are the plants? LED lighting can't efficiently penetrate a deep canopy... so training would really come into play. I'm planning on chopping just my top buds and letting the bottom ones finish out over an additional week this cycle. Selective defoliation has helped a...

Okay so good news! This is the first day where I didn't check on my plant and find signs that the deficiency was worse. The only action taken was a light "flush" (basically just 20% heavier watering) with Ph balanced tap water (we already have fairly hard water so I didn't add calcium... also I...

Week 5 Day 2 Felt like everyone needed some up close shots to see why I'm getting so excited. Four full weeks to go minimum and they're swelling and getting all pretty :oops: :oops: :oops: :oops:

Well finally got around to testing my Ph (no I have never Ph'd my water in years of growing)... about 8.2/8.3 out of the tap which is dead on with other people in my city.... so yea my nutrient issues are lockout from adding cal/mag to already high Ph water. Gonna just get that balanced and they...

Check that- had two popped when I went to bed and all 5 are awake now (plus a few of my kosher kush that hadn’t popped yet)

Enough said, watch it. The stream is currently on the approach portion so they're explaining the science behind what they're going to try.

It's one I used to get in Cali a lot before I moved back to OK... surprisingly high CBD ratio for a "mainstream" strain (7:1-3:1 depending on the pheno). I've got 6 of those and another small seedling of Kosher kush going.... plus one Cream & cheese and I want to pop more soon. I know the...
