The journey so far ... (Other newbies may find this helpful if they've survived the first 65 pages)
Glad I decided to do 2x4x5 veg tent instead of jumping right into a larger model. I think it's finally under control ... just added a variable speed 4" fan and filter yesterday ... suddenly the basement is odor free again ... but it sounds like there's a 747 revving in the corner even at low speed. The fan's screwed to a plywood board on the top of the tent, but there's no way I could have reasonably put it inside.
Tent related product reviews so far
Accurite temp/humistats are bloody awful ... a fact that may escape you if you only have 1
If you're a DIYer I'll save you some time ... you can't find solid core #18 wire for you lights locally ... go right to Amazon.
Vivosun tents are a good inexpensive product for veg but you'll go broke on duct tape for flower. Glad I experimented, now I need to find something else for the 5x5 ... possibly the Mars .... Gorilla is just out of the budget until several successful grows or one of you would like to give me a late 70th birthday present.
Vivosun 4" fan/filter/duct kit works like a charm even on low, but I wouldn't want it in the living area. Can't imagine what the 6" will sound like, although I may be able to put it inside in the 5x5.
COB and Quantum board fixtures don't put out much heat at lower wattage if you're counting on them to keep things warm.
There are almost as many nutrient manufacturers as there are strains to grow and they all claim to be the best so caveat emptor. Do your research.
RO and distilled water still need to be ph checked and adjusted before use.
When you transplant 5 plants in a 2x4 space from 1 gal pots to 3 gal pots it changes the whole climate issue and you have to get all run go keep an eye on it crazy again for a few days until you see how things are working (I may be projecting here)
Too much of anything is just as bad as too little ... light, water, nutrients, humidity, temperature .....
Daily misting seems to make plants happy. Just knock off any big water drops so the lights don't burn the leaves.
They call this plant a weed but it seems pretty finicky about almost everything so be prepared to experience horticultural OCD.
Sometimes after obsessing over a potential problem, researching things on every forum you can find, comparing your plant to all the leaf deficiency charts, watching youtube videos, and seeing if there's a way to blame the Trump administration (my personal favorite) ... you have to accept the shit sometimes just happens and they'll probably get over it.
And lastly (for now) it's REALLY HARD to know you've got to wait another 2 - 3 months to find out if you did it right
