I grow trees:bigjoint: 3 250 watters

Yep

The one over my name is a 600 watt capable heatsink that holds 2 CLU058 milled for wider spread. Heavy, 13lb. Their 250 & 320 watt heatsinks, drilled for the CLU058 and 2 different diameter lens. And a 320 watt version of the big one. I run their 250HS on an HLG120H-C1400B for 165 watts and...

@OneHitDone Doing ok for the way the world is. I used the Luna 300 and there heatsinks for a while, but their COBs require soldering to the COB. Once the CLU058 3618 was available, I jumped over to Citizen, but had the heatsinks made to my spec for the CLU058. At flip chip, the only one left...

That thing ain't shit..... Here is the SHIT!!!!! http://fcopto.com/portfolio-items/apollo-2400/?portfolioCats=4

What kind of lighting are you using and what are your temps? If running LEDs, you need to have a room temp in the high 70*s or low 80*s. Low 70* with LEDs can affect Ca uptake.

What type of an exhaust fan are you using? You shouldn't have a problem maintaining 80* with a quality exhaust?

3000K works great for veg.

Nobody has mentioned room temps??? This is one of the most important changes with LEDs. The temps should be in the low 80* due to almost no IR. 3000K/90cri was the most similar to the growth of the DE. Almost identical to the DE in stretch. If you need the stretch control in the first 2 weeks...

Why don't you ebb and flow with coco? One res change a week and auto feeds 2 or 3 times per day. I have had five footers in 2g cloth pots flooding 3 times per day and loving it. Add water midweek.

Thanks, last run I learned that purple punch will get much frostier when grown to over 4'. The 2 different tables looked almost like different strains, but the only difference was height. And this is at 20 watts per square foot:bigjoint:

If you have the height, I would let them go longer. I would go though them and clean up the thin, bottom branches and suckers. I like to keep only branches that can feed large buds and hold the weight. You should end up with a tray full of clones to sell or for the next run. I also like to do...

A 4x8 averages around $200 or more (no counting shipping, these are that lite). If you find a metal distributor (not Home Depot) $30 to $50 in square tube (3/4" and 1" work great). Harbor freight has casters for $3-$5. I weld uni-strut nuts to the bottom of the legs, so I can thread in the...

A dehumidifier is also a good way to add heat.

Unless you are growing monsters, that is way more light than I would use. I usually run about 30w sq/ft. This run is 20w and is looking better than my last at 30w. The drivers on the wall should be fine, but space them off for airflow and have a fan sweep past them. A bit of air will drop temps...

The mini split won't be needed unless your over 45watts sq/ft or if your sealed and running CO2( added dehumidifier heat). Most any quality paste will be fine.

Arctic Silver. You may need the driver in the grow area? You want fresh air and a temperature in the low 80*f.

What kind of humidity are you dealing with to start? If you vent it back into the house, you might not need a dehumidifier. I think the basement will build up moisture if only using basement air. I have my exhaust fans hooked to a temp/humidity controller. If you are only using one 1000w bulb, I...

I use 2g and flood 3X a day. 1 is almost 6'.
