  1. Hi firstly love the videos .can I ask if you get chance look at my videos of my indoor tomato growing in a telescopic pot ive made .would love to hear your thoughts .please be kind thankyou paul

  2. what is 1) ideal night time drop 2) minimum night time drop for example if daytime is 25 celcius can nite time be 23 or should it be minus 10 and what is bare minimum? thx

  3. I turned off your video would have been nice just as a courtesy to give it in Fahrenheit. I have no idea internally what Celsius is and I don't want to look it up I'll just block you

  4. I have a fan but it's sketchy to control the air temp in my little greenhouse; however, since I put heat hose in the bed I can keep the root temperature near 65F so the mornings get back to temperature quickly.

  5. nice, those temperatures are about where my seed starting closet is at, just got a little thermometer with humidity gauge to check where it's at a few times a day, if it's getting to hot I just open the door a little.

  6. June 9 Kelowna guided tour, one day, has the same price as the 5-day course. I think that might be an error. Yeah, it's five times as much as the one-day master class.

  7. 70f/21c at night & 74f/23c day (so well within optimal parameters)… good growth rate 2+ cm/day in DWC. The fan leaves are 180 deg. flat so they are taking in maximum light & that's how I validate this temp cycle

  8. Hi Curtis, this is the first time using the Red / blue / white Led light on your seedlings? it's really beneficial to the crops or just the t5 6.500k will do the job? I want to improve my seedling house .. and i'm not sure about the Led lights .. =) thx

  9. Hi Curtis, I'm looking at setting up an urban farm in the next few years with possibly between 1/4 and 1/3 of an acre. My worry is the prices you seem to sell your produce at seem a lot higher than the average of what they sell at in my country (UK). A head of Cauliflower here is £1 ($1.76 cad) at most farmers markets and around 50p (88c cad) for a kilo of carrots. I'd imagine these prices are due to all the neighbouring EU countries with cheap imports. Would you say its unlikely to profit from these prices?

  10. Hey Curtis is that a new led grow light your testing? We use led's connected to a light meter and they kick on and off to boost light levels in our greenhouse in scotland, (so on a lot) if it falls below or above a set level, basically the same idea as you just described with your heating and cooling in the greenhouse. good on the shoulder seasons and winter. love that thermometer, I have a similar one but it's nowhere near that big, looks like an old fashion barometer from a ship.

  11. Hello !I've been watching lots of your videos , not sure if i missed or u didn't post nothing about thrips! What methods do u use to get rid of them? Thank you .
