    Here are bud shots of my five Blue Orca Haze plants at 8 weeks. I harvested BOH5 at 8 weeks and the others will come down in the next 10 days. Very dense buds, with BOH4 and BOH8 leading the pack in resin production. Odors are mostly juicyfruit and floral, with varying levels of intensity...

    Hey Mr. James Marshall Hendrix, I have a question for you on the Blue Orca haze. How much do these plants stretch? I was planning to flower them from rooted clones but maybe I need to veg them a while first? Based on how these plants look now, I don't think that height will be an issue like...

    My Blue Orca Haze plants at 7 weeks from seed. I'm going take cuts in a couple days and flower the rooted clones in a few weeks. I'm a little surprised how Indica dominant they look in veg. I'm definitely not interested in an Indica buzz. Getting nice incense & musk odors in veg from #3...

    I popped a half pack of Blue Orca Haze a couple weeks ago, along with some F2s from a recent Angel's Breathe grow. I got 100% germination rate (8/8 ). Hopefully that's enough to find a nice sativa leaning pheno, as I have zero interest in knock-out Indicas. I'll be back in September with a...

    Energy and Carbon Efficient Tent Ventilation

    Thanks Corey. I added a link to Exhibit 1 in post #1 and added a section I forgot to paste in to the beginning of post #2.

    Apparently I can't post the links I wanted to embed because I don't have enough "likes." I'll add them to the above posts when I can.

    Energy and Carbon Efficient Tent Ventilation

    Calculating Heat Loss or Gain From Ventilation System This online HVAC heat loss calculator gives an equation to calculate required airflow in a heating system. The equation can be rearranged to calculate heat loss (or gain) due to ventilation: Q = L * (cp ρ ∆T)...

    Energy and Carbon Efficient Tent Ventilation

    There are several threads here on ventilation. I started one last week asking if anyone had experience with DC blowers and Electronic Speed Controls (ESCs) and, other than answering my own question in post #2, there were zero replies. I therefore assume that not many people have taken this...

    12V multi-phase blower to ventilate a 4x4 tent

    OK, I did some more searching last night on RIU and found that if the DC motor has two wires I would need a brushed motor ECU. These are significantly cheaper than their brushless motor ESC counterparts, so I think I would select an oversized ESC that has 2-3x current capacity of the motor...

    12V multi-phase blower to ventilate a 4x4 tent

    I'm going to need to set up an active negative-pressure ventilation system in my tent pretty soon when I go to flower. The tent is currently passively ventilated, meaning that I simply direct a clip-on fan at a partially opened vent at the top of the tent and air exchanges occur at a sufficient...
