250w HPS users....

[cfl...KING]

would two 85cfm 4 inch fans keep a 250w HPS cool, asuming im using a air cooled hood?

Would definitely do it for mine but mine stays cool without ventilation... at least for winter.

I have a 250w in a DIY cool tube. Im cooling it with a 105cfm axial fan & a 50cfm computer fan. The computer fan is sucking the hot air out of the tube and the axial fan is sucking air out of my flowering room. My temps stay between 28-30C.

what is the average yield under 250w? I know strain and blah blah matter but what is your average yield per plant? or per grow? I just want to hear numbers on what other people using 250w are yielding.

Hello all,

KP, my usual harvest weight is about 25grams dry of smokable material per plant per 3 gallon pots(dry) of organic soil.

My cabinet can do 4 - 6 plants in 3 gallon pots. I typically run 2-2plant perpetual harvest so I am good for about 1.8 O's +/- per 4 weeks +/-.

Others have grown larger harvests but it fits my needs. I just harvested two SDOG's yesterday. They willbe dry in 4 or 5 more days and ready for the jars. I will know then what the weight is.

While I am interested in increasing my yields, my low numbers may come from my veg time/cab. Lately I have been having troble with clones not producing enough veg growth in the 4 weeks I like to veg. I been having better luck with longer veged clones.

Seeds seem to need abotu 6 weeks for my system.

My point is your millage will undoubtedly vary.

Just my point of view.

after reading this thread I am going to change my mind about going with a 150watt hps and just bump up to a 250watt hps or possibily cmh. The benefits and results are just amazing!

Just wondering, how much noise do the 250watt hps ballast from e-conolight make? Should I be concerned in a stealth cab setup? Would it be better just going with a digital 250watt hps? Thanks

 

[Anghellic]

Heres an update on my 250 CMH grow, PK on the left, G13 on the right.

Also foil, the noise of a ballast isn't near as loud as any type of fan you would need to cool the 250, so i wouldn't worry much about it. But to answer your question, my 250 from htg supply is a very small hum, a computer is louder.

 

[F0iL]

Anghellic - Hey thanks for the helpful info. I just didnt want to spend so much on a digital 250watt so I rather go with doing a diy with the 250watt e-conolight. By the way hows the CMH doing? Are you running the 250watt in the same cab as you did with the 150watt hps? How much more heat did the 250 give you over the 150? Get a new grow journal up haha.. I loved your last grow. I am contemplating whether to go with hps or cmh. And those plants are looking mighty fine. Thanks

Hi guys
Looks like people are getting good harvests under those 250 watters.

Just thought I'd show mine aswell.
The Strain is "The Pure" from Flying Dutchmen, and it's grown in soil under 250W.

I will be chopping them in a few days.
