I'm using bio thrive and liking it. My strong plant seems to love it too. Not sure whether I want a Mars 300, or a COB set up.... maybe just 2 Mars 300's.
Also doing bag see just to test things out.
thats cool I feel ya. COB's are badass. I personally dont have the know how to solder and put one together with drivers etc.. you can build an amazing cob for like 200$ though i know that.
yeah i only said dyna gro because u can get 2 8oz bottles for less than 20$.
I myself just got the General hydroponics GO Box off amazon shippd for 38$ .. I will be using the whole 8 bottles included in the GO Box.. one of those is what you're using (biothrive)
Lets pray to sweet baby jesus you dont spend 5-6 weeks then find out your bagseed is male.. that would suck dick.. thats why i only use fem seeds.
with 2 mars 300's you could do 4 damn fine plants or flower out a 4x4 area..
I use 2 leds lights together.. a 93 actual watt full spectrum UFO along with my mars 300.. I could flower a 3x3 area with my lights or do 3 good plants in 3 gallon pots.
I just use both lights on 1 single plant... Ill put the plant directly under the mars 300 then some of the side branches hang under the 93 watt ufo.. It works good.
My last grow was an auto flower (Auto Seeds Transiberian) and I got literally almost a QP dry weight off 1 autoflower in 5 gallons of soil. 88.3 grams to be exact.
If you do end up sometime buying some seeds. Use the single seed centre.. It is however pointless to buy 1 single seed on there. the shipping will costs same as a seed.. Best bet on TSSC is to spend 35$ you can get 5 seeds plus 1-2 freebies and shipping for right at 50$ thatway.
If you need any help with some good breeders/genetics I can help ya out with some info on strains that produce well/smell/taste great /good yields of fire amazing quality smoke.
good luck to ya. If for now you only want to grow one plant at a time (what I do) .... A Single mars 300 will do one plant awesome.. You could also grow 2 autos with a single mars 300.
My friend has a single mars 600 and he loves it.. he scrogs 2-3 plants with it and it works damn well for that.
