transplanting or repotting lettuce & other greens
Comments (6)Thanks for the replies so far. The 5 or so times I've gone to go take good note of the exact varieties vs condition, I've meandered off track without mission accomplished (computer upstairs; plants outside; incomplete journaling!). I planted "many" varieties and am not very familiar with any in particular. Several of the older seeds didn't germinate... I'm getting names mixed up. What I can remember are the 2 that I have re-potted. 'Sweet Valentine' (hmm, or was that another red?!?). Most look ok, though it seems that they've grown or moved a little more out of the ground again (i.e. crown not down as far as I thought I put it). A couple of the stems below the crown/leaves (is there a specific name for that?) kind of disintegrated into nearly nothing. Maybe due to a few intermittent bouts of a bit of dehydration mixed with wet? I was hoping this sort of thing wouldn't be frequent (eg if some fungal or other troublesome organism caused more difficulty under more soil than some "ideal"). But several appear perky enough.... I maybe need to feed them a bit more too (so far only liquid seaweed at sowing & repotting, and liquid fish fertilizer at repotting). The other is 'Little Gem' - so far most look quite good, though these weren't the lankiest at repotting anyway. We seldom get weather such as yours ppod, but I'm planning to do more sowing of some varieties that claim to be more summer-suited than others. Sadly some of my mustards are bolting, not sure if that's heat or day length or what. I sowed some 'Big Red' mustard recently indoors under fluoro lights, and the stem below the cotyledons are really long (over an inch already, with no or only 1 set true leaves yet). They seem quite wispy to re-pot, but seems like I should try soon. I'll try to come back with more details, but at the rate I'm going, they may soon run out of steam. Do appreciate any chiming in....See MoreKratky method and LED's- nice combo for lettuce!
Comments (23)Thanks pixiedust! One of these will power 8 of the LED's I listed above- I bought 5 of them for my 2x4' panel that has 40 (4x10) of the LED's: http://www.dx.com/p/waterproof-ip65-50w-10-series-5-parallel-integrated-constant-current-power-led-driver-100-240v-398675#.VuQOT0d0ac0 For the aluminum sheet, you can get it most anywhere, just make sure it is at least 1/8" thick to dissipate the heat. Ebay has them here but I didn't buy from this seller: http://www.ebay.com/itm/1-8-125-Aluminum-Sheet-Plate-24-x-48-6061-/271025780988?hash=item3f1a6538fc I found that a small fan blowing a gentle breeze across the top of the panel is all that is needed to keep it cool. I ended up gluing some little temperature switches to the panel (because i like to tinker) so the fans only come on when needed but this is not necessary. I did notice the fans didn't run at all over the winter down in my basement. You will need some thermal glue to adhere the stars to the aluminum sheet: http://www.ebay.com/itm/Hot-Thermal-Compounds-Conductive-Heatsink-Adhesive-Industrial-Glue-For-PC-GPU-IC-/351461284609?hash=item51d4b99b01 And then just wire the 8 stars in series to each power supply. Note that this will drive the Cree XT-E's at their full rated power which is not the most efficient thing to do, I have since started designing my newer lights to run more optimally. One other thing, I built my unit based on the 2x4' home depot shelving units. Was pretty handy to already have the frame and shelves. I just dropped in the aluminum panels instead of shelves where I wanted them. Since mine was going in the unheated basement I boxed it all in with insulating foam covered with silver mylar. Good luck with your lettuce!...See MoreRomaine lettuce is not safe to eat amid a new outbreak of illness
Comments (28)Just noticed the couple of questions...No, no fillers needed. Last nights salad with a frittata. Easily 4 large salads. The rest put in a smoothy at work. this one was just a big blend. I've gotten so far ahead of myself I'm producing much more than we can consume. And a pic this morning of what is downstairs under lights. I have about 30 varieties I grow in rotation. Not always a blend but over-produced for the holiday long weekend. Sometimes just the daikon, red Rambo, china rose radish with fresh cucumber sliced. Simple lemon dressing. Or the crunchy sunflower shoots with the five blend pea shoots and a fresh sliced golden beet, different dressing. I will probably purchase once or twice a nice buttery Boston head for a avocado wrap at some point but the variety is so flavor punched I use mandolin paper thin veggies like a salad taco. No real need for any extra head lettuce. 10-12 days to harvest. And still fresh up to a couple weeks. Un-cut. Nothing fresher than a scissor snip an hour before brunch/dinner. Because these are young and not producing fruit, (like a tomato), a simple Ikea led light will grow macro greens. Last winter we had a month of gray snowy days. I set up a small shelf in my kitchen pantry and grew without issue....See MoreCDC advises Romaine lettuce is not safe to eat in any form
Comments (42)Sheeisback, I don't know where you are, but here we can grow from March-May and then again in the fall. After June it is too hot here. But look into CSA's, local farms, and hydroponic growers. If you are looking to start a business or invest, I think it's the way of the future. It actually uses a lot less water than conventional growing. Although based on my tour, it is still extremely labor intensive and requires 24/7 oversight. https://www.tegahillsfarms.com/...See More- 6 years ago
