What side would you mount the led inside the U or outside Or can I get away with just letting them hang in the air mounted on angles on edges only Cheers

Can I get away with thin aluminium sheet metal for running these or u channels? I’ll be running them at about 10-15w per I think

Did you not use a filter?

How did next door know what you were up to ?

What would you guys recommend as the best system for a veg room. I have a sealed grow room, the veg room has limited space and height. I plan to keep the clones in here for 2 weeks or so after rooting and move the net pot straight to the flower system. I’m considering food and drain but not...

Yeah I know they sell one specific but I can’t find anyone in my country selling them. USA, aus, canada even New Zealand has a sale of this cord for blue lab, but not where I can find near me. It’s surely a standard dc connector but I can’t figure out which one. I’ve tried to figure out how...

Anyone able to help me out with the name of the power connector I need for a blue lab guardian monitor? Snapped my old cable in two so need a replacement Ordered a dc power adapter off amazon with the same amps and volts but the connector isn’t the same as the old one.

Ac units no longer over heat. I need to upgrade the air circulation as the ac units are set to 16c but the part of the room furthest from the ac is hitting 32c. I’m mounting some air circulation fans now which should improve this

Yeah I noticed that, there are prefilters in front of the coil I need to make sure I clean regular. It would be a shame if I have to open them up to clean as I’ve sealed them up with expanding foam Going back into the room Soon to check on the test to see if the room has handled the temp ok

The power would be split between the two as far as I’m aware and if your ac unit can’t keep up the rooms will overheat. But if your flipping 0.00 - 12.00 and 12.00 to 0.00 then you shouldn’t have that issue?

I’ve upgraded to the 10 inch flex and a 10 inch RVK exhaust fan. Just waiting for all the expanding foam to dry around all my clamp joints for an extra air tight seal then I’ll run a proper test to see if they have improved. Can tell instantly that the airflow through the pipe is massively...

Wouldn’t you just use a 5 ton Split ac with two of the indoor units and let them run with no mods? The one in the room with lights on will kick in when lights are on due to the heat build up and the one in the room with lights off with kick off due to the heat dropping?

This is for a sealed grow room the duct is for a portable dual hose ac exhaust. The temps can get up to 40-50c The expanding foam would just be to seal the gaps in the rigid foam, it wouldn’t push on the flex It’s a very tight space grow, hard to get any photos. Vertical grow using space...

I’ve ordered 10 inch non insulated flex as I plan to use expanding foam insulation + rigid foam to create a insulated duct around the duct

Unfortunately no as in my country literally nobody uses hvac... except maybe industrial freezers or something. summer temps get to 25c for a week or two if we’re lucky... most of the year it’s below 10c. Cheapest I found would work out an extra 400 ish usd for the amount of duct I need. If...

I only have the option of a 6inch rigid or a 10 inch flex. As i can’t find a supplier of the 10 inch rigid I need. In this situation what is better, 6 inch rigid it’s smaller but less friction or 10 inch flex larger but more friction?

Well I’ve went and bought a 10 inch RVK fan and 10 inch flex ducting and I will test both. Still interested in anyone’s input though will be here by end of week so I can test it

I’ve got an issue with my portable acs over heating. Currently got an extended run of 6 inch pipe with a booster fan but it’s just not enough. I can’t get a rigid pipe any bigger than 6 inch without literally costing nearly a 1000 usd here... it’s a rip off. But I can get 10 inch flexible...

When you have a 4 x 12 room would you still have 2 either side of the lamps so 6 bulbs or 4 bulbs? What benefits do you notice?

How do you have them spaced in each 4 x 4? I feel like long tubes with large spaces between them must get really uneven coverage. I seen the manufacturer specs show them on the outside edges of the 4 x 4 is that what you do? Do you see much benefit from them?
