    Let's see HOW your grow your Dews!

    I'd like to see some shots of how you guys grow your plants. I'm just getting into Dews and am interested to see all your various actual setups (diff for pygmies?), pots in tubs, lights so far from plants, how many lights, etc. If you can tell (or show) temp and humidity of your areas that would be great too. Do you always have plants sitting in water? What sort of growing media is good for that since peat becomes just mud when you do that.

    I of course have all my CP books and their theories but I'd like to see what you guys are actually doing in practice. I never did well with dews when I tried to grow them in the past. My best grower was the D. adelae which popped up in my N. hamata moss and lived / bloomed / made a pest of itself in a net pot of LFS & orchid bark in highland conditions. But the standard advice of "setting pots of peat in an inch of water" only lead to slowly rotting plants for me.

    So I'd like to do better if I intend to get more interesting species than the D. spathulata and D. capensis I have and I'd like to keep these nice too of course!

    once i finish up with finals this week and go home, i will post pics of my whole setup. I will be having a big seed giveaway soon, so I'd love to get you started with some more unique dews.

    For now, I'll post 2 pics of one of my tubs, and just fill you in on my "techniques", which I've learned/stolen from books and a ton of people on this forum:
    I use the tray method, and let the water level drop considerably before adding any again.
    The key is intense light (with the dews nearly touching them, to only a few inches away).
    Another key is getting an appropriate media (which has been pre-rinsed well) for the plants, which best suit your conditions. Some swear by a peaterlite mix for all sundews, while I've found that I need to use a peat:sand mix to avoid algae development and bug issues. In some conditions, peat:sand will be too dry and it may cause the plants to wither up. I also tend to use live sphagnum for temperates and "water-lovers".
    Once you give your sundews these key ingredients, they should dew up nicely and turn bright red. Then you can feed them and make them grow fast/flower like crazy. Every 2 or 3 months, you may have to do a "maintenance check" to clean algae out of the trays and top water your sundew pots to avoid mineral/salt buildup. If you do all of this, your dews can pretty much live forever!

    Here are the pics: DISCLAIMER- I don't recommend using a setup like this! It will make much more hassle for you than is needed.
    First planted in the tub, around Dec. 1st, 2008 (dews had been neglected prior to repotting)



    3/13/09


    I will post another pic of this tub once I get a new pic. Last time I checked, everything was flowering except a few D. aliciae.

    Alright mate. The light fixture in this picture is a professional 4 bulb T8 high bay fixture
    complete with reflector. I adjusted how it hangs on the rack so that shorter plants dont miss
    out on light. (click to see to see a bigger picture)

    As I learned in my physics classes, light intensity, along with gravity, does not act linearly with
    respect to distance. So every inch closer you can get your plants. the better it is. Almost all
    dews love lots of light.

    Here's a shot of some dews on the tray system.

    For the average dew, I use peat/perlite, or peat/sand, or a mixture of all 3. It just depends
    on what's in my mixing tray. I haven't noticed much of a difference between any of the
    mixes.

    Here are some pygmies. They're on the far end of the lights, as they will never get very tall
    and they love light. I used to grow these out in full sunlight and they loved it, but I'm moving
    to an apartment in the fall, so I needed to bring them indoors.

    I also grow these on the tray system. For media, I use a sandier peat/sand mixture. I
    wouldn't use perlite since their root system pretty much consists of a single root that dives
    down into the pot. This root likes to go deep, so I use 4 inch pots and fill them up to near
    the top with media.

    When growing under lights, height is an important consideration. This pot of D. multifida var.
    extrema is really pushing the limits.

    So is this madagascariensis pot

    And this graminifolia


    All those dews coexists happily with my highland nepenthes which also grow well in these
    conditions. When the lights are on, they get pretty warm. I leave the window in my room
    open all day and night to give some temperature fluctuation and airflow. I live in Los Angeles
    so it rarely gets too hot or too cold.

    I have also started feeding my dews betta bites. This really accelerates their growth.

    I think that's about it.

    Thanks guys. What keeps your peat from becoming a muddy mess that starts to become anoxic (stinky) in the warmer months sitting in water like that? That's what happened to my dews in the past. Can you use straight LFS to keep the soil from becoming poisonous?

    That rubber maid tub of dews is awesome! A great looking setup for starting seeds - an idea I might steal lol! How do you have it lit? Do you keep the lid on it (until they flower obviously)?

    That could work quite well for seeds, but I'd recommend the smaller shoebox variety. The one pictured is actually 8 or 9 inches tall, which uses a TON of sand and peat. You can actually grow most sundews with little or no humidity, so I never have the lid on. One of the pics I post will show my normal growing setup. When I start my pygmy gemmae, I place a sheet of saran across the top of the tub, and then I took it off after a month, when they grew to a decent size. T

    I have the top of the tub almost touching my T-8 bulbs. I have 4 tubs total across and 2 two-bulb T-8 fixtures going the horizontal way across them. As of now, most of the dews are 3 -5 inches away from my lights. However, I wish they could be much closer. My other sundews are less than a 1/2 inch from the lights, and they color up much faster.

    I normally only use a peat:sand mix with my African sundews, and I've found that if you rinse the media really well, and use a mix that favors the sandier side, there is little to no anoxic activity, even if you never let your tray dry out.
    To keep the soil from becoming "poisonous", all you have to do, is rinse the peat & sand really well before potting your dews up. Then make sure to thoroughly top-water your plants at least every 2 months to wash away mineral and salt buildup that develop from using the tray method.
    I use dead or living LFS for all my "water-lovers", which I grow in small 3-inch or less pots. Examples are D. intermedia, D. rotundifolia, etc.

    I'm no sundew expert, but one thing I do know for sure is that LFS turns a lot faster than peat moss.

    I just put all my plants onto my rack, and mostly they acclimatize. D.Peltata spp. ariculata has a leaf that's blood red. I use 2 gro-lights and 1 flourescent. I bought them from Walmart :3 It says it gives you 75W of lights but use 17Ws so I refer to it as 51Ws. Everything just grows and turn red. :3

    btw.Cpplantaholic I love you site! does that mean when you click your site you get a virus? I'm scared to click it again :3 I always click it when you post!
