I'm getting to a stage where my small but tedious legal grow hobby could use extra help. I tried with a patient, donating time for extra medicine but it didn't work out (forgot to water plants), so I'm thinking of recruiting a friend who is interested and competent. He would help in exchange...

I want to switch my veg room to LED after seeing the monstrous growth in one plant during veg under a cheap Amazon LED, compared to T5 and even the Ushio veg 600w. The room is about 100 sq ft. Who's the best vendor out there, but still cost effective? Presently I'm running about 800W's worth...

Anyone growing their own nutrients- flowers, grasses etc that have all the nutrients you need to grow without any/many external inputs? Would like to learn more if so

I've been using a 2 gallon tank with pump wand, it's been better than hand watering and even adjusts for foliar spraying, but I'm wondering if there's anything better out there?

I let the plant dry out after flushing. Usually about 3-5 days no watering and they're ready. I harvest a few branches at a time into a sterilized bucket, cutting the fan leaves beforehand. Next they go into drying room- upside down for the bigger buds, the smaller buds are cut and placed onto...

I'm looking at a greenhouse, it's 30x90, owner said it's double poly. On a 30 degree day on winter last year it was around 60 in the greenhouse, had to take off my coat and the wood stove wasn't even running yet. Has a large exhaust fan and electricity nearby (200A). It's on a concrete slab...

Layed out pond liner in an indoor veg room and house is smelling like plastic, is this stuff carcinogenic? Smells gross.

can someone tell me if this appears to be male plants or female plants that were pollinated? I had a couple of males, one I think I got to a little bit late and I'm not sure. Thank you

For next year's outdoor crop I'd like to have more beneficial things to put into my plants, things that are relatively easy to grow, that can either be harvested when ready to use, or harvested, processed somehow and preserved to be used as fertilizer later. If I were to set aside .25/acre...

I'm so curious, the hot air exhaust from a 12x12 flower room with 8 or 9 lights, other than having more oxygen, would it contain chemicals from the lights? I'm asking because since my flower room is next to the living room and it gets cold here, I could exhaust into my living room and get some...

Opposite the winter flower room will be veg room. flower room will have climate control and dehu/heat/ac combo. since lights are air cooled blockbusters 1000W and the veg room about 10 feet away gets the coldest in the house, I was thinking would it be possible to pull air from the ceiling...

Noticing weirdness in leaves, any tips/pointers appreciated. Is it phosphorous deficiency? My water pH tests at 8 and when I add nutes it's around 6.5, soil pH is 7. I only did Nute pack (beneficial inoculant) yesterday and today.

I'm entertaining the idea of going outdoor greenhouse but not sure where to start. Any suggestions on type of greenhouse for zone 8, southern Oregon? What's required in order to grow year round, something that will support lights like Gavitas? I'm seeking bids for getting electric to it. Just...

Does anyone use trimming machines? What's your favorite?

I noticed changes in color of leaves and lack of nutrogen although I've been dilligent about feeding regularly (typically feed half recommended, feed full, feed full, compost tea, flush, flush, flush). Also noticed slower growth over the past 2 weeks, so I picked up a Blue Lab pen suspecting...

Found some used blockbuster hoods, the v3 6". The come with ballast and bulb all for $100 each, guy said they've been used for one run. Is this a good deal?

Sorry if it's a dumb question but can UVB be done outdoors? What would you buy? Also does UVB have to be used only during lights on, or could it be used at night?

Was wondering, can I put my cutting in root riot plugs, and insert those into net pots which insert into a clone bucket or will it absorb too much water and drown out the clones before they can root? So far I've just been sticking clones into the neoprene inserts, and waiting like 14+ days...

Trying to determine why I'm seeing stunted growth all of a sudden. In a soil grow, when I feed, should I ph test the water with nutrients in it? Would a 5 ph water being fed to a 7 ph soil bring the soil's ph down eventually? lastly, what should one do if their water source has a too high or...

A guy I know mentioned dual purpose thermostats, programmed to pull cold air from outside when the room hits 77 for example, and push hot air out at the same time. Are there any climate control devices that will accomplish this? Since I have cold winters i'm thinking this may save $ on...
