What's just plain wrong is the way that this guy starts a post.Sorry buddy, your just plain wrong..... I have 3 400W MH running in a 10x10 room pretty much side by side (as well as a 3 1/2 x 4 T5 CFL panel). Im not exhausting AT ALL, no heat problems at all, nope .... Indeed, the T5's are throwing off more heat than the 400W MH simply because less airflow is allowed around the bulb. The room is well insulated, double insulated actually....
I tested my 400W MH's... they each pull respectively 389-413 watts, steady 3.7 amps......
I am running T5's and CFL's side by side with the MH's using different T5 horticultural Brand bulbs (each to their own section) as well as different MH brands (different bulb, ballast, hood, respectively)...... once a plant passes 2 weeks or so in veg, it responds Twice as well to MH as the T5's and other fluorescent bulbs..... Even different strains at different distances from the bulbs, they ALL respond better to the MH, and the root systems too.....
Im not going to argue about any of these points....... the evidence is easily placed in pictures all over this site and the rest of the net, the info is out there easy enough to find, to each their own is fine.... I would be the last to bag on anyone for vegging under fluoros...... but the first to strait up bluntly tell a person they are wrong, having empirical data and other evidence to back up my claims
Exactly SomeGuy, which was the main point I was trying to make. That and the fact that it is cheaper to run T5's and ALMOST as good as MH. I have both as well. T5's take up a lot less space, produce a lot less heat, require a lot less ventilation, make a lot less noise, and they also cost less initially and over the long-run. In a tent, you don't want to veg under HIDs if you even have to think about heat. And like I said earlier, sometimes it's nice not to have your vegging babies growing at lightspeed. Thanks for the back!A 10x10 room is a whole diff ball game then a 2'x4' closet. Even with the doors wide open, I was at 85+ deg. It took venting the heat out of the space to drop it to 76-80 which is where I'm at now.
All I'm saying is, if your cramming something into a tight space, you shouldn't just ignore heat output, it does matter.
Ultimately there are pros and cons to each side, Drella just needs to understand the full scope of both sides so an informed decision can be made. Like I said, if you plan on running perpetually and want the fastest growth possible yeah maybe you should go with the MH. Otherwise, I would SUGGEST the T5's but that's up to Drella.
