General Cultivation Q&A

Hi everyone, Sorry if this a really stupid question; Can hydroponic nutrients such as Canna A+B be used in a non hydro soil set-up? Currently indoors, hand watering and will be outdoors in the ground being drip fed from a water tank when they're 2 months old. If not, what would you recommend?

I'm looking into doing a DWC set-up after my outdoor grow has finished and was looking for peoples opinions on what you think is the most appropriate reflector would be for a room with 4 Large/Tall plants probably around (room size 2mx2m or 2.5mx2.5m) I'm planning on running 2 lights, and I'd prefer to stick with 2x600HPS or smaller if possible. Im only a beginer so please bear with me ...... be gentle, it's my first time ::

Can I grow from seed about a week or two. Flip to flower to see sex then reveg without problems if any.

OK, I really want to get opinions from some of the knowledgeable people here. I've had some input on another grow from a few esteemed growers whose opinions I respect a great deal. However, their advice is contrary to my own common sense, and I would like to see if anybody has some good botanical information that clarifies this situation for me. My question is: Is it really true that lower fan leaves in a scrog grow take nutrients away from the flowers in the canopy, and that they should therefore be removed? I simply cannot understand how it can be a good thing to remove lower fan leaves when they generate sugars/energy from photosynthesis, and therefore contribute t…

Just thought I'd make a thread for the DWC growers to post some comparison pics showing the quick growth rate of DWC. I also thought it would be good for the non DWC growers to see just how quick plants veg in DWC. Please add pics if you have them These are Lush x Blueberry seedlings that I put into the DWC tub 7 days ago. The roots were just beginning to come out of the rockwool cubes. 7 days later they look like this with nice thick stems and the beginning of some nice branching. Naycha

Few more weeks to go not long now, was given clones at start of year that were in a bit of trouble tried to bring all 3 back to life, was able to save one. Made sure she makes up for the loss. Last pic. Was given seeds from sweet seeds tried 3 creame caramel first, two germinated sucsesfully one never. Out of the two one more died from over nutes, one is left and will be next on my list after this grow. Will have a diary for the creame caramel grown in nothing but perlit. Cheers haze Sorry pics a shit

Hey guys I'm about to grab one of these little units to control temp it's a elemental day and night fan speed controller.anyone else used this little gizmo on here.been told that it doesn't completely shut off fans they only slow down or speed up to reach set temp.

Gotta love a good scrog,feel free to post ur scrog pics here these 2 beauties are Pineapple express @ 46 days 12/12 in RDWC cheers

I have a question related to carbon filters- is it possible to invert a carbon filter having the filter outside the tent drawing the air out of the tent through ducting then into the filter? Has anyone had success with this?

feminize your own seeds with bananas = ethylene gas

Quick query, have equal parts coco, canna terra professional and course perlite for growing, along with canna terra nutes I think, is mixing at one third to each for my mix going to be fine? It's been quite a while since they were purchased and can't find the notes on what ratios to use. Cheers
