    Which is most optimal? (COB vs SamsungStrip)

    20 x 20 grow area 18 x 18 light's area ideally. Lights just under your grow area. Run pretty hot at maximum, without sufficient cooling I wouldn't recommend. Minimum aluminium u channel. Recommended more than that. Using 10mm flat aluminium bar and 12mm heatsink and a fan on roof. Still warm...

    Which is most optimal? (COB vs SamsungStrip)

    First check your sizes. Your space 20 x 20. Those lights are 56cm long, your area is 50cm. Yes that driver is a constant current driver, cable of running 200.2Watts and maximum 1.4A. Any Samsung strip with a maximum of 1.6A this driver will run pretty efficiently if maxing out the 200.2W...

    Thermal Management

    Thanks "better coverage more efficient "was always planning on running two sets . As you can see the beams are a problem. So two sets a must. Last week This week Heatsinks are doing their job on top of that flat bar. Nice a cool to touch. 22mm thick ;-)

    Finished the 2nd set, delays in shipping. Needed it big time as the freebie seeds didn't like the new light that much ;-)

    The Gentlemen (movie) realistic ?

    Guy Ritchie's THE GENTLEMEN has hit cinemas worldwide with a weed farm empire at the heart of the story. Sugavision's cannabis made weed film history. Found the company that made them. Also a few other TV shows as well. Sugavision.

    The Gentlemen (movie) realistic ?

    No problem. Plants not real, thought so myself and some computer generated graphics no doubt. Had to laugh at the lights. (Latest technology) Very pretty but. Worth the watch and couldn't believe it was Hugh Grant. Big change from his usual movie. Thought Colin Farrell was outstanding...

    The Gentlemen (movie) realistic ?

    Just watched The Gentlemen movie from director Guy Ritchie. Really enjoyed it first time round. Then watched it back to see how realistic it was. If you have not seen it, give it a watch. Just for the weed factor if nothing else. Know plants were real in the old Cheech n Chong movies. These...

    Biogrow and biobloom

    First feed give it half the maximum ml at least. Better to safe than sorry, even a quarter of the recommended dosage. That's just general rule. If your leaves are nice and green then no problems so far. Pics would help. Advice is only generally. Each strain and plants differ. Using biobizz I...

    Soil preference?

    Can't go wrong with Foxfarm products. Bag I showed you produces around 16/17 gallons

    Soil preference?

    Big difference in coco. So much faster. Yes they can get watered more often. No nutrients in coco. You provide them. So far my favourite is Canna for coco. Can water up to 3 times a day in coco. Again just lift pot see the weight. Can see the coco getting lighter in colour when drying.

    Soil preference?

    Grow in soil takes a little longer. Grow in coco a lot faster. On average 3 to 4 months soil. Coco average 2 to 3 months. Soil can get problems with insects. Coco no problems. Generally I grow autoflower in coco. Photoperiod in soil. Just my preference.

    Which is most optimal? (COB vs SamsungStrip)

    I run S02 on 1A. Maximum I crank it up to is 1.4 A

    Which is most optimal? (COB vs SamsungStrip)

    Based on 400 watts .. Can see the efficiency and flux for each. How many you can run for 400w. Can get a better spread with more lights with S02 or S03. Double the amount of strips as you can see.
