Newbie for cannabis and very glad to have found this online resource. We farm here @ 44'N in Maine so we have a lot of infrastructure already (insulated greenhouses and high tunnels) so we are going with what we know (and have) and not investing in lights etc. Maine just passed as law that residents can grow, at any time, twelve (12) mature plants, six (6) flowering plants, and unlimited seedlings. Which is awesome. Also, we are allowed to give away 2.5 oz at any time (and no limit to transactions) to any 21+ adult (without $ in return). Well, there is already a strong barter culture where I am so this, again, is awesome. We have a 12x24' passive solar greenhouse that we normally use for cucumbers and tomatoes but this year we are going to dedicate it to 8-10 cannabis plants and see how we do. As you can see from the attached photos we use aquaponics and, while we plan on using cloth bags this year, it is a nice resource for nitrogen rich watering! Have eight (8) beans which are four (4) of Northern Light Auto and four (4) White Widow Photo. I figured I would play with both and see how they responded to my particular circumstances. Got too excited and germinated one of each on Feb 28 and days late both popped (thanks CKS!). Since days are still lengthening here, I have a 100W CFL hood lamp (from the chicken coop) supplementing until 7pm (so 13 hours daylight). Hoping to transfer these into 2 gallon cloth bags and up-pot to 5 and then 10 gallons.
That does suck you lost some good sounding seedling
