Can still get 600w green powers. I presume they are approved everywhere, but it's not getting any better than that.
I keep thinking it's time to stock up. My big guys with £25 pricing have dried up, and now I'm looking at £37 each. What shops have always asked, except for the rip-off one's.
£30 gets a whole damn light now. If you accept a barn shade and the cheapest hungarian lamp.
I'm in the market for an electronic, but always find them noisy, and give them away.

I have pro-ultra shades and magnetic ballasts, that I will never need. So if the good stuff dries up, I can help out in the UK

Snatch them up before they're gone before you regret it.

I'm testing out this light in my tent right now
1732581446911.png

Ambient room temp is hovering around 70 F. The temperature 24" directly below the center of the bulb in the closed tent has been a constant 82(+-0.4) F. So, a constant temp of 12 F warmer than ambient room temp. That's about as low of a temperature as I can get with my inline fan. The fan exhausts back into the room that the tent is in (I have a dehumidifer).

I can't get my light any higher in the tent and I can't get my plant canopy any shorter. I'm not using CO2. I should be able to grow good buds with these temps and the canopy 24" away from the open bulb, correct? I will also install a 7" oscillating fan to circulate the air just above the canopy.
