I've got heat management pretty much under control very easily in the 4x4 tent. The AC Infinity exhaust fan has a great amount of flow . I have two intakes on the tent. I have a large one at the very bottom for the majority of the air flow through the tent. I have a much smaller intake at the top that is directed at the HLG DIABLO 650R. That's the Diablo's only negative is that the driver is not remote mounted. With circulation fans placed on the diagonal, I get a very even air flow and temperature in the tent.Yes, this AC Infinity unit only uses 50 Watts, that unit is much more powerful, that might be the difference. Using full light boards underneath want something I wanted. My room is really bright and efficient as it is. I was looking to add another 50 to 100W of additional lighting to try and fatten up those lower buds.
If you want to add more power and don’t care about electricity or heat, then I would do it
The only other thing that I will probably change is making a bit thicker amount of straw to make sure the worms will come up to the proper level without the light shying them away.
Now, being totally realistic, there are just some instances where this can't really be utilized that well or at least optimally. If I'm growing a short quick growing auto, these lights would become more of a side lighting set up. Just not enough room to be able to turn the lights up without harming the plant when used as an under canopy light.
And really with this particular spectrum of this light, I don't think I'm going to add the supplemental deep red that I have in the 2X4 tent. I had intended on running the Mars Hydro Supplemental Deep Red and Infrared lighting. The infrared to wake them up and put them to sleep quicker and then the deep red for its obvious attributes. I think I've got really good results from the use of my deep red in my 2X4 tent.
I do have to say though that with the HLG DIABLO 650R, I do have quite firm buds all the way down on my current grow of Asian Haze. They are smaller but pretty close to being the same density. II think a great deal of that is from the red that's in the light. I've seen very similar results from using the Mars hydro supplemental deep red in the 2X4 tent. The penetration of the red is just much better and more efficient. And that's why I think that this supplemental under Canopy light will be a good improvement on the current setup in the 4x4 tent.
If my 2X4 tent was a taller gorilla tent, I would later on try the same system in that smaller tent. That's 540 watts!
The Mars Hydro tent is really just too short to do something like this. The ducting openings are not really conducive to good air flow either. I don't utilize, in any tent, the screened velcro inlets at the very bottom. That's just too much work to make it consistent. I'm not opening and shutting these on all the tents at the change of light cycles!
I use ducting to bring in my air to my tent and direct it to where I want it. I have to take outside air and direct it all the way down to the bottom in the Mars tent. I lose a lot of efficiency with that long ducting. Even with two inlet ducting bringing in air, I pretty much have to have the 6 inch fan set one click higher than what I have on the 4x4 tent to maintain the same VPD growroom wide.
Damn Asian Haze! It's rabbit hole food!
