Hi! I made a grow a while back in a pc case. I've learned some things although the end result was not what I wanted, I still learned a lot. I've chosen "The Church" for this grow: The Church (by Green House Seeds) :: SeedFinder :: Strain Info This time I'm choosing Deep Water Culture and a closet w/ a 50 liter (13.2 galons), a air pump and two airstones. I'm starting w/ about 70w of CFL's for vegging and two pc fans, but I should upgrade when it goes to flowering This is Day 1 of the grow: (today) how it looks: all covered up: temperature inside: monster bucket the seed: lots of bubbles: electrical wiring: (need to fix) GHE Tripack FloraNova (28eur) lianli pc fan: lights:
it looks like you have your netpot in the water upto the rockwool ,do you ? the rockwool look to wet,is it ? keep the netpot 1/2 inch above the water. do you have nutes in the water ? middy
The rockwool is not completly submerged into the water and there are no nutes in it Photos: Also, I've added some mylar
keep the net pot 1/2 inch out of the water, the bubbles bursting on the surface will keep the bottom inch or so wet, just let the rockwool dry up a little bit i think but it is hard to tell from pics , is it wet or damp ?. water from the to untill the roots come through. i normaly let the roots come through the bottom of the rockwool around an inch before putting them into the buckets. what temp is your res ? 68 is the sweet spot but with a nice clean res with seedlings in, i would up the temps to around 72, seedlings like it a bit warmer, but so do the bad things that you don´t want in your res, so keep a close eye on the water for any rapid change in ph. middy
i found that soil drainage pipe fits perfect around my net pots, i cut a bit 2,5 cm wide, great for holding my foil to the buckets and it has given me a few more liters of water space, so its a bonus . try and get the res temp down if you can 20c/68f middy
Thanks middy. The temperature is at 23ºC. The only way i can lower my temperature is by increasing the distance from the lights, and I don't have the amount of lumens I want yet. Still waiting for the end of the month to buy more lights. 2 Days ago: Today: The pH is a hard thing to control in a 50 liter (13 galons) bucket, everyday it goes up to 7, but I try to keep it under 6. Also I think I will run out of pH down (solid solution) before harvest. I've added nutes for 40 liters of water.
something isnt right then.. in a larger container the ph should be more stable. Are your PPM going down as your Ph goes up?
By res temp i believe Middy was referring to the reservatory, as in water temperature, and i believe there may be a confusion with your communication because I haven't seen a water thermometer.
The res temp (taken w/ pH meter) is at a stable 21ºC. The temperature that I was giving was from the termometer close to the plant. The pH is much more stable now, it goes up a average of 0.1 a day.
