This is where I plan to mount the 24w T5HO I purchased.

I didn’t get chance to even go into my room last night.

Hopefully tonight I’ll get the work done.

It will be mounted using the hanging clips to the underside of the middle shelf so that I can start seeds on the lower shelf.

Day 54 since flip.

Current feeding EC in the reservoir is 0.7 and 0.2 is the source water.

Dutch Pro bloom A/B and a small amount of MKP with pH down to reduce to 6pH.

nugs are rock fucking solid.

To be fair I’m loving this LED from Mars hydro.

Previously was using 200w CFL to start then onto 400w MH then the 400w HPS after stretch.

Apparently my 24w T5 is arriving tomorrow.

if it does I’ll be getting some Blue Gelato 41 from barneys on the go ready for going straight in after I harvest this.

Watch out for mold dude. Had that for the first time ever indoors under LED. The buds are just that much denser. Humidity was only 50% too.

Looking good tho!!

propagation shelf set up but not finished fully yet.

The shelf brackets hindered me slightly.

I’ve Mounted the light at an angle to eliminate the issue with the brackets for now.

i will add a small baton of wood under the shelf to move the light lower to clear the brackets so that it Lines up better in the shelf.

I can't get my temps above 23/4c at best so I need to change the tent or the lighting.
I'm using 643w to run a 300w light and it's still not enough power/btu,s.

That said with less than ideal temps they're doing fine, all topped between 5-6th node 2 days ago.

Dude I’ve been running 20C ambient on my scrog net which is about 36” away from the light source and the rooms doing fine.

i think it’s another over complication aiming for 28C with LED as it’s working just fine for me.

I could though remove the driver from the Mars hydro led frame and mount it lower down in the room which would help to move some heat through the room and plant.

Your right, I'm getting fkg brainwashed here...I've had this before (last year lol) with no problems, at the time others chimed in with low/lower temps and zero problems.

But...I've just plugged in a 400w mh into the 1x1mtr 15-20mins and it's toasty 26.32c I'll veg under it for 10-14 days then gonna back to led to flower.

It won't suit everyone's set up but if it does its worth considering.

I like a space in my tent now for me to get inside it, I used to pack but I'd rather sacrifice some yield for space to work in.

After watching this clip I made up a reflector.

Reflectivity test (as photons are expensive).

Hi guys! We just made a short video where we test the reflectivity of different materials commonly used in DIY grow spaces. Enjoy!

Nothing fancy but it wasn't difficult to see that it made a difference.

So yesterday I had a chance to take some measurements using the Mars tsl 2000 as a source.
With the reflector completely above the light.

With the reflector inline with the light.

That's a considerable difference for 20" of mylar.
